WARNING

6 Mercury lamp or xenon lamp

(for an epi-fl attachment)

The mercury lamp (or xenon lamp) used for the epi-fl attachment requires special handling. To use the system safely and correctly, read the warnings below and be aware of the dangers. Also carefully read the manual for the super high-pressure mercury lamp power supply (or high-intensity light source) and the manual (if provided) by the manufacturer of the lamp and follow their instructions.

Warnings about the mercury lamp and the xenon lamp

1) The mercury lamp (or the xenon lamp) radiates ultraviolet light that is harmful to the eyes and skin when the lamp is turned on. Don't look at the lamp directly. Direct viewing of light from these lamps may result in blindness.

2) Gas is sealed under very high pressure inside the lamp. The pressure increases when the lamp is on. If the lamp is scratched, dirty, subjected to high external pressure or physical impact, or used beyond its operational life, the sealed gas may escape or the lamp may burst. In such cases, there is a possibility of inhaling the gas, injury by broken piece of the glass, or other accidents.

3) When the lamp is on, the lamp and its surroundings become extremely hot. Do not tough the lamp and its surroundings to prevent a burn injury and do not place flammable materials near the lamp to prevent a fire.

4) Use only the lamps specified in this manual. Using other than the specified type of lamp could result in an accident, such as a burst.

Because safety is a top priority in the design of Nikon products, the hazards described above should not pose any danger as long as you heed all of the warnings and cautions in the manuals and use the system only for its intended purpose. However, the hazards described above could lead to an accident if you fail to heed all of the warnings and cautions in the manuals, if you strike the system, or if you attempt to disassemble the system. Therefore, always be sure to heed all of the warnings and cautions.

7 Turn off the lamp before changing the filter cubes

(for an epi-fl attachment)

Before changing the filter cubes, be sure to turn off the light source of the epi-fl attachment. If the lamp is lit and the filter cubes are changed, dangerous ultraviolet rays may be radiated.

8 Place the D/UV slider into the optical path

Notes on Handling the Microscope System

1 Handle with care

This microscope system is a precision optical instrument. Handle the microscope system with care to avoid shock on impact. In particular, objectives may loose accuracy when exposed to even a weak physical shock.

2 Weak electromagnetic waves

The power supply for this microscope system emits weak electromagnetic waves. There is a possibility that some precision electronic devices are affected by the electromagnetic waves. To prevent bad influences, locate such electronic equipment away from the microscope system. If a TV or radio reception is affected, move the TV or radio set farther from the product.

3 Dirt on the lens

Scratches or fouling such as fingerprints on optical components (lenses, filters, and so on) will degrade microscope images. If these parts become dirty, clean them as described in Capter 6, "Care and Maintenance" at the end of this manual.

4 Dirt on the lamp

Never touch the lamp with bare hands. Dirt or fingerprints on the lamp will result in uneven illumination and reduce the service life of the lamp. Always wear gloves when handling lamps.

5 Installation location

This microscope system is a precision optical instrument. So, the usage or storage in an inappropriate environment may result in malfunctions or poor performance. Consider the following factors when selecting an installation location:

• Fix the microscope FN1 body securely on a baseplate or a vibration isolator with bolts.

• When the microscope is mounted on a microscope slider such as an XY mover, fix the microscope

body on the microscope slider securely with bolts or so on to prevent the microscope from toppling over.

• The halogen lamp light source, the lamp house, and the optical fiber light source need to dissipate heat when the lamp is lit. So, locate such heat sources at least 10 cm away from walls.

• Choose a location less exposed to hazards in the event of collisions, earthquakes, or other potential disasters. Choose a sturdy vibration isolator, desk, or table for the base of the microscope system.

• Avoid bright locations where the product is exposed to direct sunlight or immediately under room lights. If the ambient light is bright, the microscopy image will be affected.

• Choose a location that is free from considerable dust or dirt.

• To avoid splashes, do not use the microscope system near water.

• Make sure the ambient temperature is 0 to 40°C and humidity is 85% or less. Using or storing the

product in hot, humid locations may result in mold formation or condensation on lenses, performance degradation, or malfunctions.

• Select a layout that allows easy removal of the power cords from the AC inlets on the power supply

and the optical fiber light source in the event of an emergency.

Page 10

Notes on Handling the Microscope System

6 Focus knobs

• Never turn the focus knobs on the left and right sides of the product in opposite directions at the same time. Doing so may damage the product.

• Turning the coarse focus knob past its farthest point will damage the product. Never use excessive

force when turning the knob.

7 Protect the ports (when the trinocular eyepiece tube or the variable magnification double port tube

is attached).

Always attach caps to any port not in use. When caps are provided with equipment, use them. If any port is not covered with a cap, extraneous light and dust may come into the equipment.

8 Handling filters (for an epi-fl attachment)

• Interference filters (especially excitation light filters, which are exposed to strong light) deteriorate over time. Replace the filters as necessary.

• Filter characteristics may alter if the filter is exposed to high humidity. To prevent changes or degradation of filter characteristics, avoid using or storing the filters under conditions of high humidity or high temperature and avoid subjecting the filters to rapid temperature changes. When a filter is not in use, store it in a desiccator or hermetically sealed container with a drying agent.

• The filters attached in the nine types of filter cubes listed below have sharper wavelength characteristics than standard filters. However, due to their sophisticated coatings, they must be handled with special care. In particular, take care to avoid abrasion from cleaning. Follow the procedure described in Section 1, "Lens Cleaning," of Chapter 6, "Care and Maintenance."）

Single band filter cubes: DAPI, FITC, TxRed, GFP

Multi band filter cubes: F-R, F-T, D-F, D-F-R, D-F-T

9 Handling

There are two blades in front of the D-FLD dark-field illumination cube to prevent light from coming through. Do not apply any pressure onto the blades to prevent malfunctions.

(1) Vertical tube adapter

A photo adapter is attached as a standard accessory for photomicrographic equipment. To use this adapter, insert it into the vertical tube of the eyepiece tube and fix it with three screws on the vertical tube.

If you wish to use a TV camera, you must attach an optional TV adapter into the vertical tube.

(2) Disabling the Clicking of the Optical Path Selector Lever on the T Eyepiece Tube

and the F Eyepiece Tube

There is a "NO CLICK" switch on the eyepiece tube mount part. When this switch is slid in the direction of the arrow, the clicking of the optical path selector lever is disabled. So, if you need to eliminate slight vibrations resulting from the clicking action, slide this switch with a narrow piece of metal such as the hexagonal screwdriver provided.

Diopter Adjustment

Diopter adjustment compensates for differences in visual acuity between the right and left eyes, improving binocular observation. It's hard to adjust the diopters with the standard procedure because of the sliding nosepiece. So, adjust the diopters as described below.

Turn the diopter adjustment rings on both eyepieces to align their engraved lines with the

edges of the outer tubes of the eyepieces. (They are the standard positions for the diopter rings.)

Before adjusting the interpupillary distance, focus on the specimen with a low magnification objective by following the steps of 1 to 10 in Section 2 of Chapter 1, "Microscopy."

Adjust the interpupillary distance so that the viewfields for both eyes come together. Doing so will make observation through the binocular eyepieces with both eyes easier.

Converge until the right and left view fields coincide.

5.1

The LWD condenser must be focused and centered so that the light passing through the LWD condenser forms an image at the correct location (the center of the optical path) on the specimen surface.

Before focusing and centering the LWD condenser, focus on the specimen with a low magnification objective by following the steps of 1 to 11 in Section 2 of Chapter 1, "Microscopy."

When you wish to use the 4x objective with the LWD condenser, attach the additional lens for 4x magnification into the turret of the LWD condenser and place it into the optical path. When you wish to use an objective of a magnification higher than the 4x magnification, you need not attach the additional lens.

5.2

Adjusting the Condenser Aperture Diaphragm

The aperture diaphragm is important because it is related to the resolution, contrast, depth of focus, and brightness of the optical image. Turning the condenser aperture diaphragm lever on the LWD condenser changes the size of the aperture diaphragm.

As the aperture diaphragm is stopped down, resolution and brightness are reduced while contrast and depth of focus are increased. Conversely, as the aperture diaphragm is opened, resolution and brightness are increased while contrast and depth of focus are reduced. It is not possible to adjust one pair of characteristics without affecting the other.

Generally, a satisfactory image with appropriate contrast can be obtained with an aperture setting that is 70% to 80% of the numerical aperture of the objective. The numerical aperture is indicated on the barrel of each objective.

Example: when the numerical aperture of an objective is

0.80,

0.8 x 0.7 to 0.8 = 0.56 to 0.64

If the aperture diaphragm is stopped down too far, the resolution is reduced; therefore, except when viewing a nearly transparent specimen, we do not recommend stopping down the aperture to less than 60% of the numerical aperture of the objective.

(2) For the bright-field microscopy with the 4x objective

Attach the additional lens for 4x magnification into the DIC prism N2 position of the condenser turret of the LWD condenser and fix it with a set-screw. And then, place it into the optical path. (* There is no indication about the 4x magnification on the condenser turret.)

When you wish to use an objective with a larger magnification than the 4x objective, you need not attach the additional lens.

(3) For the DIC microscopy

Attach an objective for the DIC microscopy.

Attach a DIC prism into the condenser turret of the LWD condenser that meets the specification of the objective. You can see the DIC prism type on the side of the objective.

(4) For the microscopy under the diagonal illumination

You can observe a nearly transparent specimen by improving the contrast under the diagonal illumination. And, you can rotate the slit for the diagonal illumination around the optical center to change the orientation of the shade of the specimen.

Attach a slit for the diagonal illumination into the condenser turret of the LWD condenser.

Rotate the turret and place the slit into the optical path.

Rotate the slit orientation ring on the turret to adjust the illumination light orientation.

6 Field Diaphragm

Field Diaphragm

The field diaphragm restricts the illumination light to the area on the specimen to be observed. Operating the field diaphragm ring changes the size of the field diaphragm. For normal observation, the size of the diaphragm should be such that it is just outside the edge of the viewfield.

If a broader area than necessary is illuminated, stray light will enter the optical system, creating flaring, reducing the contrast of the optical image. The operation of the field diaphragm is especially important in photomicrography; generally, the best results are obtained by stopping down the field diaphragm to just slightly larger than the image area or the area that will be reproduced on the film, that is, the size of the picture composition frame (for a digital camera, the size of the CCD).

8 Water Immersion Operation (Water Immersion Type Objective Handling)

Water Immersion Operation (Water Immersion Type Objective Handling)

An objective with a "W" mark is a water immersion type objective. It is designed to focus on a specimen at a working distance in water. To use this type of objective, apply water (normal saline solution or such) into a chamber. And lower the objective to make its tip touch the water.

When you wish to observe a specimen to a depth of 0.2 mm or so on from the surface, for example a sliced brain, you are recommended to perform an observation under infrared rays or to use a water immersion type objective with a correction ring, Plan 100xW.

CAUTION:

Leaking water from the chamber can give rise to corrosion of the stage or the condenser lens. If water in the chamber spills on the stage or on the condenser lens, it should be wiped out soon.

After use, wipe off water from the tip of the objective, then follow up by wiping with absolute alcohol.

If you observe water stains, apply a small amount of neutral detergent and wipe gently, then follow up with absolute alcohol.

Cleaning the Oil Immersion Type Objective After Use

To wipe off immersion oil, use petroleum benzine. For optimum results, we recommend following up petroleum benzine with absolute alcohol (ethyl or methyl alcohol).

If petroleum benzine is unavailable, use methyl alcohol. However, methyl alcohol does not clean as well as petroleum benzine, it will be necessary to wipe the surface repeatedly. (Usually, three- or four-times wipe is sufficient to clean the lenses.)

WARNING：

When using petroleum benzine or absolute alcohol, always follow the instructions

provided by the manufacturer. These liquids are highly flammable and must be kept away from flames and sparks.

10 Variable Magnification Double Port Attachment

Variable Magnification Double Port Attachment

You can attach an eyepiece tube onto the front port of the variable magnification double port attachment and a 2/3 inch TV camera onto the rear port of the variable magnification double port attachment.

You can select the port condition between the simultaneous usage of both ports and the front port usage only.

When the simultaneous usage of both ports is selected, 100% of visible lights goes through the front port and 100% of infrared rays goes through the rear port.

The magnification for the rear port can be selected from among x0.35, x2, and x4.

With the rear port, the water immersion type objective of x16 and the numerical aperture 0.80 enables various observations from a low magnification with wide view field to a high magnification with high resolution without changing objectives.

Take note of that vignettings may occur when the magnification for the rear port is x0.35. This is not a malfunction.

Front port

Rear port

The front port can be used for the following observations:

• Bright-field microscopy

• Microscopy under the diagonal illumination

• DIC microscopy (combined with the FN-IR/ISA DIC IR

analyzer or the D-FL U-EPI FL epi-fl attachment)

• Fluorescent microscopy (combined with the J-FL epi-fl attachment)

The rear port can be used for the following observations:

• Infrared bright-field microscopy

• Infrared microscopy under the diagonal illumination

• Infrared DIC microscopy (for DIC observations under

Care and Maintenance

Lens cleaning

Do not let dust, fingerprint, etc. get on the lenses. Dirt on the lenses, filters, etc. will adversely affect the view of image. If any of the lenses get dirty, clean them as described below.

• Either brush away dust with a soft brush, or else gently wipe it off with a piece of gauze.

• Only if there are fingerprints or grease on a lens, dampen lightly a piece of soft, clean

cotton cloth, lens tissue, or gauze with absolute alcohol (ethyl or methyl) and gently wipe off the dirt.

• Use petroleum benzine to clean off immersion oil.

• Do not use petroleum benzine to wipe the entrance lens in the eyepiece tube.

• Absolute alcohol and petroleum benzine are highly flammable. Be careful when handling

it, when around open flames, when turning the power switch on/off, etc.

• When using petroleum benzine or absolute alcohol, always follow the instructions

provided by the manufacturer.

Painted component cleaning

Do not use organic solvents such as alcohol, ether, or paint thinner on painted components, plastic components, or printed components. Doing so could result in discoloration or in peeling of the printed characters. For persistent dirt, dampen a piece of gauze with neutral detergent and wipe gently.

Storage

Store this product in a dry place where mold is not likely to form.

Store the objectives and eyepieces in a desiccator or similar container with a drying agent.

Put the dust-proof cover over this product to protect it from dust.

Before putting on the dust-proof cover, turn off the power switch of the power supply (flip it to the "O" position) and wait until the lamp house gets cool sufficiently
