sales office.

Caution when using

Pay your utmost attention to the following points.

When red LED’s of LASER EMISSION on FV5-LDPSU are lighting, it indicates that laser is

being emitted. When microscope is connected, the laser is emitted from objective tip.

Reflection may enter your eyes or light may be scattered around. Care must be taken in this

case. In addition, do not see the sample while laser is scanning.

When two red LED’s are
lighting, it means “laser

Safety Considerations

Regarding settings of DIP switches located at back panel of FV5-LDPSU, refer to VI 1 –

Back panel switch settings.

z Set this system on robust base.

z This system generates heat. When installing this system, make it sure that a space of 10cm or more is

provided, left and right of the system, and do not block vent openings.

z Power cable may be molten when it hits hot place of lamp housing. When installing, make it sure that the

power cable is adequately apart from the lamp housing.

z Never insert a metal piece into vent opening as it may cause failure or electric shock.

z Do not apply your hand or finger to laser beam that comes from mounting hole of objective lens or objective

tip.

If your hand or finger is exposed to laser beam, it may cause a skin hazard. In addition, never insert a

mirror into light path as the laser beam may come outside and it may enter your eye which is very

dangerous

z Do not set or remove the sample during laser emission (laser scanning). If you set or remove the sample

in such a case, reflection from the sample may enter your eye which is very dangerous. Moreover, do not

look at the sample during laser emission (laser scanning).

z System performance as well as system safety cannot be guaranteed in case that cover is detached or the

system is disassembled with use of tools. Never disassemble the system.

z Do not bend or pull fiber excessively. Do not step on the fiber. If the fiber is broken, laser beam may leak

which is very dangerous. In case that such unlikely event occurred, turn power of laser power supply unit

to OFF position immediately and contact our sales office. (when using FV5-LD405 only)

z Always use the power cord provided by Olympus. If no power cord is provided, please select the proper

power cord by referring to the section “PROPER SELECTION OF THE POWER SUPPLY CORD ”at the

end of this instruction manual.

Safety Considerations

z Connect the power cord correctly and ensure that the ground terminal of the power supply and that of the

wall outlet are properly connected. If the equipment is not grounded, Olympus can no longer warrant the

electrical safety and performance of the equipment.

z Before connecting cord and cable, verify that the main switch is turned to O – (OFF) position.

z Mixture (alcohol (3): ether (7)) that is used for cleaning optics is high inflammable so that utmost care must

be taken when handling with respect to fire and main switch ON/OFF. When using ether, it is

recommended that the room is well-ventilated.

z Be careful so as not to apply any excessive force to connecting cord or cable as it is very weak against

bend or twist.

z Do not change fuses that are located above the power cord connector. When change of fuses is required,

contact and consult with our local sales office.

z Do not carry the semiconductor laser head by hand. It may be damaged as it is very delicate tool.

z Do not swing around fiber carelessly. If fiber being emitted is swung around, laser beam may hit human

body that would cause a hazard. (when using FV5-LD405 ONLY)

z When you dispose of this system, it is necessary to handle it as an industrial waste. In case that you

cannot dispose it yourself, deliver it to our local sales office.

10.1

This section specifies safety precautions and control measures to be taken by the user of a laser product, in

accordance with its hazard classification. Often users can use the manufacturer's classification of the product

for classification of the laser installation, thus avoiding all measurements. This section is supplied for the

user's information. Nothing in this section shall be considered as constraints or requirements imposed upon the

manufacturer. For installations where Class 3R laser products emitting energy outside of the 400nm to 700nm

wavelength range or Class 3B or Class 4 laser products are operated, a laser safety officer should be appointed.

It should be the laser safety officer’s responsibility to review the following precautions and designate the

appropriate controls to be implemented. If should be the laser safety officer's responsibility to review the

following precautions and designate the appropriate controls to be implemented. Wherever practicable, laser

protective enclosures should be used for lasers of Class 3B or Class 4. Warning labels should be placed upon

removable parts of protective enclosures or at service connections where a hazard is introduced by their

removal or by disconnection.

Safety precautions

General

The purpose of safety precautions and control measures is to reduce the possibility of exposure to hazardous

levels of laser radiation, and to other associated hazards. Therefore, it may not be necessary to implement all of

the control measures given. Whenever the application of any one or more control measures reduces the possible

exposure to a level at or below the applicable MPE, then the application of additional control measures should

not be necessary.

If a user modification of a previously classified laser product affects any aspect of the product's performance or

intended functions within the scope of this standard, the person or organization performing any such

modification is responsible for ensuring the reclassification and relabelling of the laser product.

The remote interlock connector of Class 3B and Class 4 lasers should be connected to an emergency master

disconnect interlock or to room, door or fixture interlocks (see 4.4).

The person in charge may be permitted momentary override of the remote interlock connector to allow access to

other authorized persons if it is clearly evident that there is no optical radiation hazard at the time and point of

entry.

The beam emitted by each Class 1M and Class 2M laser product classified under condition 1 of table 10, each

Class 3R laser product emitting energy outside of the 400nm to 700nm wavelength range, and each Class 3B or

Class 4 laser product should be terminated at the end of its useful path by a diffusely reflecting material of

appropriate reflectivity and thermal properties or by absorbers.

Open laser beam paths should be located above or below eye level where practicable.

The beam paths of Class 3R laser products emitting energy outside of the 400nm to 700nm wavelength range

and Class 3B or 4 laser products should be as short as practicable, should have a minimum number of

directional changes, should avoid crossing walkways and other access routes, and should, where practicable, be

enclosed. The beam enclosure (for example, a tube) should be securely mounted but preferably not rigidly

attached to (or provide support for) beam-forming components.

10.7

Care should be exercised to prevent the unintentional specular reflection of radiation from Class 3R, Class 3B

or Class 4 laser products. Mirrors, lenses and beam splitters should be rigidly mounted and should be subject to

only controlled movements while the laser is emitting.

Care should be exercised to prevent the unintentional specular reflection of radiation from Class 1M and Class

2M laser products from surfaces that may focus the beam.

Reflecting surfaces that appear to be diffuse may actually reflect a considerable part of the radiation beam

specularly, especially in the infra-red spectral range. This may be potentially hazardous for longer distances

than one would expect for purely (Lambertian) diffuse reflections.

Special care needs to be taken in the selection of optical components for Class 3B and Class 4 lasers and in

maintaining the cleanliness of their surfaces.

Potentially hazardous specular reflections occur at all surfaces of transmissive optical components such as

Specular reflections

lenses, prisms, windows and beam splitters.

Potentially hazardous radiation can also be transmitted through some reflective optical components such as

mirrors (for example, infra-red radiation passing through a reflector of visible radiation).

Eye protection which is designed to provide adequate protection against specific laser wavelengths should be

used in all hazard areas where Class 3R laser products emitting energy outside of the 400 nm to 700 nm

wavelength range, Class 3B or Class 4 lasers are in use (see clause 12). Exceptions to this are

Eye protection

a) when engineering and administrative controls are such as to eliminate potential exposure in excess of

the applicable MPE;

b) when, due to the unusual operating requirements, the use of eye protection is not practicable. Such

operating procedures should only be undertaken with the approval of the laser safety officer.

c) maximum permissible exposure (MPE);

d) optical density of eyewear at laser output wavelength;

e) visible light transmission requirements;

f) radiant exposure or irradiance at which damage to eyewear occurs;

g) need for prescription glasses;

h) comfort and ventilation;

i) degradation or modification of absorbing media, even if temporary or transient;

j) strength of materials (resistance to shock);

k) peripheral vision requirements;

l) any relevant national regulations.

Eye protection which is designed to provide adequate protection against specific laser radiations should be

used in all hazard areas where Class 3B or Class 4 lasers are in use (see clause 12). This requirement does not

apply to Class 3B laser products with not more than five times the AEL of Class 2 in the wavelength range

from 400 nm to 700 nm. Additional exceptions to this are:

a) when engineering and administrative controls are such as to eliminate potential exposure in excess of the

applicable MPE;

b) when, due to the unusual operating requirements, the use of eye protection is not practicable. Such

operating procedures should only be undertaken with the approval of the laser safety officer.

Depending on the type of laser used, associated hazards involved in laser operations may include the following:

Medical supervision

a) the value of medical surveillance of laser workers is a fundamental problem as yet unresolved by the

medical profession. If ophthalmic examinations are undertaken, they should be carried out by a

qualified specialist and should be confined to workers using Class 3B and Class 4 lasers;

b) a medical examination by a qualified specialist should be carried out immediately after an apparent or

suspected injurious ocular exposure. Such an examination should be supplemented with a full

biophysical investigation of the circumstances under which the accident occurred;

c) pre, interim, and post employment ophthalmic examinations of workers using Class 3B and Class 4

lasers have value for medical legal reasons only and are not a necessary part of a safety program.

11.2.1

There may be a considerable hazard from the ultra-violet radiation associated with flashlamps and CW laser

discharge tubes, especially when ultra-violet transmitting tubing or mirrors (such as quartz) are used.

11.2.2

The visible and near infra-red radiation emitted from flash tubes and pump sources and target re-radiation

may be of sufficient radiance to produce potential hazard.

11.3

Most lasers make use of high voltages (>1 kV) and pulsed lasers are especially dangerous because of the stored

energy in the capacitor banks.

Collateral radiation hazards

12.1

Three aspects of the use of lasers need to be taken into account in the evaluation of the possible hazards and in

the application of control measures:

The practical means for evaluation and control of laser radiation hazards is to classify laser systems according

to their relative hazard potential, and then to specify appropriate controls for each class. The use of the

classification system will in most cases preclude any requirement for radiometric measurements by the user.

The classification scheme relates specifically to the accessible emission from the laser system and the potential

Procedures for hazard control

General

a) the capability of the laser or laser system to injure personnel. This includes any consideration of human

access to the main exit port or any subsidiary port;

b) the environment in which the laser is used;

c) the level of training of the personnel who operate the laser or who may be exposed to its radiation.

hazard based on its physical characteristics. However, environmental and personnel factors are also relevant

in determining the control measures required and a responsible person should be designated as laser safety

officer, to be responsible for providing informed judgments on situations not specifically covered by this

standard.

The following details relate to safe operation of laser products in:

– outdoor and construction environments where administrative controls often provide the only reasonable

approach to safe operation;

– laboratory and workshop environments where engineering controls may play the greatest role;

– display and demonstration environments, where pre-planning, delineation and control of access often

provide the only reasonably practicable approach to safe operation.

12.2

The hazard potential for Class 3B and Class 4 lasers may extend over a considerable distance. The range from

the laser at which the irradiance or radiant exposure falls below the appropriate MPE is termed the nominal

ocular hazard distance (NOHD). The area within which the beam irradiance or radiant exposure exceeds the

appropriate MPE is called the nominal ocular hazard area (NOHA). This area is bounded by the limits of

traverse, elevation and pointing accuracy of the laser system and extends either to the limit of the NOHD or to

the position of any target or backstop. The exact NOHA will also depend on the nature of any material within

the beam path, e.g., specular reflectors.

The NOHD is dependent on the output characteristics of the laser, the appropriate MPE, the type of optical

system used, and the effect of the atmosphere on beam propagation. Formulae and examples for calculating the

NOHD are given in annex A.

12.3

Hazard evaluation for Class 3B and Class4 lasers used outdoors

Personal protection

The need to use personal protection against the hazardous effects of laser operation should be kept to a

minimum by administrative controls, engineering design and by beam enclosure.

When personnel may be exposed to potentially hazardous laser radiation (Class 3B and Class 4) adequate

personal protection should be provided.

12.4

Only Class 1 or Class 2 laser products should be used for demonstration, display or entertainment in

unsupervised areas. The use of other classes of lasers for such purposes should be permitted only when the

laser operation is under the control of an experienced, well-trained operator and/or when spectators are

prevented from exposure to levels exceeding the applicable MPE.

Each demonstration laser product used for educational purposes in schools, etc. should comply with all of the

applicable requirements for a Class 1 or Class 2 laser product. A demonstration laser product shall not permit

human access to laser radiation in excess of the accessible emission limits of Class 1 or Class 2 as applicable.

recautions for

Laboratory and workshop laser installations

12.5.1

Precautions are only required to prevent continuous viewing of the direct beam; for Class 1M, Class 2 and

Class 2M, a momentary (0,25 s) exposure to radiation in the wavelength range400 nm to 700nm as would occur

in accidental viewing situations is not considered hazardous. However, the laser beam should not be

intentionally aimed at people. The use of optical viewing aids (for example, binoculars) with Class 1M, Class

2M and Class 3R laser products may Increase the ocular hazard. Additional precautions for Class 1M, Class

2M and Class 3R laser products are given in 12.6.2.

12.5.2

Class 3B lasers are potentially hazardous if a direct beam or specular reflection is viewed by the unprotected

eye (intrabeam viewing). The following precautions should be taken to avoid direct beam viewing and to control

specular reflections.

Class 3B laser products

a) The laser should only be operated in a controlled area.

b) Care should be exercised to prevent unintentional specular reflections.

c) The laser beam should be terminated where possible at the end of its useful path by a material that is

diffuse and of such a colour and reflectivity as to make beam positioning possible while still minimizing

the reflection hazards.

NOTE - Conditions for safe viewing of diffuse reflections for Class 3B visible laser: are: mini

distance of 13 cm between screen and cornea and a maximum viewing time of 10 s. Other view

conditions require a comparison of the diffuse reflection exposure with the MPE.

d) Eye protection is required if there is any possibility of viewing either the direct or specularly reflected

12.5.3

Class 4 laser products can cause injury from either the direct beam or its specular reflections and from diffuse

reflections. They also present a potential fire hazard. The following controls should be employed in addition to

those of 12.5.2 to minimize these risks.

Class 4 laser products

a) Beam paths should be enclosed whenever practicable. Access to the laser environment during laser

operation should be limited to persons wearing proper laser protective eyewear and protective clothing.

Beam paths should avoid work area where possible, and long sections of tubes should be mounted so that

thermal expansion, vibration, and other sources of movements in them do not significantly affect the

alignment of beam forming components.

b) Class 4 lasers should be operated by remote control whenever practicable, thus eliminating the need far

personnel to be physically present in the laser environment.

c) Good room illumination is important in areas where laser eye protection is worn. Light-coloured diffuse

wall surfaces help to achieve this condition.

d) Fire, thermally Induced aberrations in optical components and the melting or vapourization of solid

targets designed to contain the laser beam, are all potential hazards induced by the radiation from

Class 4 lasers. A suitable beam stop should be provided, preferably in the form of an adequately cooled

metal or graphite target. Very high power densities can be handled by absorbing the radiation over

several reflections, each reflecting surface being inclined at such an angle to the incident radiation as to

spread the laser power over a wide area.

e) Special precautions may be required to prevent unwanted reflections in the invisible spectrum from far

infra-red laser radiation and the beam and target area should be surrounded by a material opaque at

the laser wavelength. (Even dull metal surfaces may become highly specular at the CO2 wavelength of
10,5

Local screening should be used wherever practicable to reduce the extent of reflected radiation.

The alignment of optical components in the path of a Class 4 laser beam should be initially and periodically

checked.
