Safety Regulations

Description

The individual modules fulfill the highest requirements for observation and documentation of Leica stereomicroscopes of the M series.

Designated use

Refer to "Safety Concept" booklet

Non-intended use

Refer to "Safety Concept" booklet

Never use M series microscopes or their components for surgical procedures (e.g. on the eye) unless they are specifically intended for that purpose.

The instruments and accessories described in this operating manual have been tested for safety and potential hazards. The responsible Leica affiliate must be consulted whenever the instrument is altered, modified or used in conjunction with non-Leica components that are outside of the scope of this manual.

Unauthorized alterations to the instrument or noncompliant use shall void all rights to any warranty claims!

Place of use

Refer to "Safety Concept" booklet

Set up the electrical components at least 10 cm from walls and combustible objects.

Avoid large temperature fluctuations, direct sunlight and vibrations. These conditions can distort measurements and micrographic images.

In warm and warm-damp climatic zones, the individual components require special care in order to prevent the buildup of fungus.

Responsibilities of person in charge of instrument

Refer to "Safety Concept" booklet

Ensure that:

The M series stereomicroscopes and accessories are operated, maintained and repaired by authorized and trained personnel only.

All operators have read, understood and observe this User Manual, and particularly the safety regulations.

Safety Regulations (cont'd.)

Light sources: safety regulations

Protective measures of the manufacturer:

UV protection screen in front of the specimen plane prevents the user from looking directly into the UV rays.

Dummy filter carriers in the free positions of the rapid filter changer prevent direct UV radiation from reaching the eyes.

UV filters are installed in the observation beam paths to protect the eyes.

The stray-light protection on the lamp housing prevents irradiation of the hands.

Warning

UV radiation could damage the eyes. ­Therefore:

Never look into the light spot on the specimen plane without a UV protection screen.

Never look into the eyepieces if no excitation filter is in the beam path.

Fill empty filter positions with dummy filter carriers (e.g. M165 FC).

Do not select a white, strongly reflective background for the specimen.

Supply unit

Always unplug the supply unit from the power supply:

Safety Regulations (cont'd.)

Lamp housing

Never open the lamp housing while the lamp is switched on. Risk of explosion, UV exposure, blinding!

Before opening the lamp housing, allow it to cool off for at least 15 minutes. Danger of explosion!

Never cover the air duct on the lamp housing. Danger of fire!

Mercury lamp

Follow the user manual and safety regulations provided by the lamp manufacturer, and, in particular, the section on how to proceed if a lamp breaks and releases mercury.

For transport, remove the mercury lamp, transport it in its original packaging and protect moving parts in the lamp housing using the transport anchors.

When it has reached the end of its rated life (follow the manufacturer's specifications and the minute meter on the supply unit).

To minimize the risk of explosion, replace a discolored mercury lamp promptly.

Leica Microsystems assumes no liability for damage caused by exploding, incorrectly installed or improperly used mercury lamps.

Congratulations!

The New Leica M Series

The introduction of the Leica M50, M60 and M80 adds three new highquality routine stereomicroscopes to the proven M-Series range from Leica ­Microsystems. The optical brilliance and the wide range of accessories make them the ideal microscope for quality assurance and similar industrial applications.

Magnification in stages or zoom

The Leica M50 stereomicroscope includes precisely reproducible magnification levels for repeated examinations, measurements, drawing or photography of objects under absolutely identical conditions. The five easily selectable positions can be set without removing the eyes from the eyepieces. This ensures that your results remain comparable at all times without great efforts.

The Leica M60 and M80 stereomicroscopes can be used for a wide range of routine applications with the 6:1 / 8:1 zoom and switchable ratchet steps. The large working­ distance and the brilliant imaging power shows you the finest details of your specimens without losing your overview of large workpieces.

Common to all microscopes is the Leica range of accessories. Whether you need a variety of illumination types, a wide selection of objectives or the Leica swinging-arm system – there is a solution for everything there!

Do you already own stereomicroscopic equipment and are thinking of switching to Leica? No problem! Leica M50, M60 and M80 fit into microscope carrier with a diameter of 76 mm and are therefore compatible with many suppliers. You can simply continue to use your components and add the proven Leica stereomicroscopes.

The Modular Design: Everything is Relative

The Leica M series provides maximum flexibility in choosing equipment, thanks primarily to the modular configuration and the compatibility that Leica has painstakingly maintained for decades. The optics carriers, eyepieces, bases and more can be combined in any way you choose, allowing you to create the microscope that best suits your needs.

Despite this, you will notice that the controls and individual components do not differ significantly. Whichever configuration you choose, you will quickly feel right at home.

Have a special request? Let us know!

Leica Microsystems enjoys an exceptional reputation when it comes to devising customer-

specific solutions. If you have a special request that cannot be met with standard parts, contact your Leica consultant. We have a solution for every problem.

Maximum Compatibility

Leica engineers were careful to ensure that the new Leica M series—like its predecessors— remains compatible with existing series. This means that objectives, bases, tubes and so on can be reused.

Objectives

All objectives of this new generation have the same reference focal length as the objectives of the MZ generation. If you prefer, you can therefore continue to use the previous Leica objective series.

Tubes

The interface between the optics carrier and the tube has remained the same, so existing tubes fit the new M series. The new tubes are designed for eyepieces with field number 23, while the predecessor models were only designed for field number 21, resulting in a smaller object field.

Eyepieces

The new M-series eyepieces have an audible and tangible click to provide immediate feedback in case of accidental adjustment.
