The Illuminator Unit is to be fixed to the main Microscope Body with 3 screws using Allen wrench supplied along with Illuminator. Three Tapped Holes are provided in the Base Unit as shown in Diagram below.

Important Note: Make sure the Power Cord is not connected at this stage.

After the Illuminator Assembly is properly fixed, connect the cable from Lamp House to the Socket provided in Base of Microscope as shown in below picture.

Adjusting the Aperture Diaphragm

In order to achieve good resolution of the optical image, the contrast and depth of focus it is necessary to control the numerical aperture of the Illumination system through the lever provided on the illuminator - See Diagram above.

Reducing the aperture increases the contrast & the depth of focus. Increasing the aperture increases the brightness & resolution.

1. Place a specimen with plain surface on the stage.

2. Focus on the specimen with 10x Objective.

3. Remove one of the Eyepiece & look through the Eyepiece Tube to ensure the diaphragm image is visible in the pupil of the Objective

4. It is recommended to keep the Aperture Diaphragm image in nearly 3/4th of the pupil of Objective. Adjust with aperture lever your required image quality.

INITIAL SETUP & ASSEMBLY

Mounting the Objectives

Base unit is assembled with co-axial focus mechanism, turret and stage plate, as per procedure below:

Install the observation head using the following procedure as shown in Fig. 4:

1. Using the 3mm allen wrench (provided), loosen the Head Locking Screw (1) and remove the dust cover cap provided in dovetail cavity as well as on the observation head dovetail.

2. Mount the Observation Head by engaging the dovetail provided at the bottom of the head into the dovetail cavity provided in the microscopes arm.

3. Tighten the Head Locking Screw (1) after positioning the Observation Head as desired. See figure 4.

Settle down the nosepiece by rotating coarse adjustment knob towards back. Remove the dust prevention caps from the nosepiece.

Mounting of Eyepieces

Fig. 5

Screw the objective with the lowest magnification into the revolving nosepiece from the left side of the microscope. Turn the nosepiece clockwise and mount the remaining objectives in ascending magnification order. (Fig. 5)

Clean the objectives periodically.

Be sure to cover any unused threaded position on Turret

with the dust prevention caps to prevent from dirt and dust from getting inside.

Insert the eyepieces into the ocular tube of Observation Head after removing the protective caps from the observation tube.

For Dioptre Adjustment on Eye Piece See Page 7

Adjusting the Interpupillary Distance (IPD)

Fig. 7

Adjusting the Diopter

The inter-pupillary distance adjustment consists of regulating the two eyepieces to align with both the eyes’ pupils so that you can observe a single microscopic image through two eyepieces in stereo vision. This greatly helps to reduce fatigue and discomfort during observation.

While looking through the eyepieces, move both eyepieces laterally until the left and right fields of view coincide completely. The position of index dot (•) indicates the inter-pupiliary distance value.

Note your interpupillary distance so that it can be quickly referred to in the future. This is especially important if multiple users work with the microscope.

Adjust the Diopter setting to “0” position by matching the fiducial lines on both eyepieces. Now looking through one eye piece (eith , turn the coarse and fine focus adjustment knobs to bring the specimen into focus.

er left or right)

Adjust the focus of other side of eye piece by looking through it and at the same time optimizing the Dioptre scale of the Eye Piece.

Fig. 8

Using the Eye Guards

When Wearing Eyeglasses Use with the eye guards in the normal, folded-down position. This will prevent the eyeglasses from being scratched (Fig # 9 Part 1).

When Not Wearing Eyeglasses Extend the folded eye guards outwards (direction of the arrow) to prevent ambient light from entering into your line of vision (Fig # 9 Part 2).

Placing specimen on the stage

Place the Metallurgical specimen on the stage plate. The specimen should have sufficient polished - reflective surface.

In case your microscope has mechanical stage mounted, use appropriate holder plates. (See details on Page 13)

Adjusting the Focus

DETAILED OBSERVATION PROCEDURE

1. Click ” ” as shown in Figure 17.

2. Rotating the light intensity adjustment knob in the direction of the arrow

the main switch to I (ON)

increases the brightness and rotating the knob in the opposite direction decreases the brightness. The intensity bar on the knob indicates the direction of intensity level.

Focusing Procedure - use of Coarse focus knob & Fine Focus Knob.

1. Rotate the coarse adjustment knob (1) clockwise so that the objective (3) is as close as possible to the specimen (We recommend starting

with 10X).

2. While observing the specimen through the eyepieces, slowly rotate the coarse adjustment knob (1) counterclockwise to lower the objectives.

3. When coarse focusing of the specimen is obtained (an image is

Fig. 14

observed), rotate the fine adjustment knob (2) for fine detail focusing.

4. Adjusting Torque for Coarse Focus Knob.

Rotation of tension adjusting ring towards coarse knob will increase focusing torque. Rotating tension adjusting ring towards stand will decrease the focusing torque.

Working Distance (WD) The WD refers to the distance between each objective and the specimen, when acute focus of the specimen is obtained.

Care & Maintenance

Your microscope has been engineered for a long and safe operational life with the least amount of maintenance required. In general, routine maintenance is limited to keeping the microscopes working parts lubricated and optics clean. Always cover the microscope with the provided dust cover when not in use.

1. Optical Cleaning:

1. The objectives have been adjusted for a tight fit to prevent any damage during transportation. To remove an objective, rotate it counterclockwise while gripping it with a rubber sheet, etc. to avoid any slippage.

2. To clean the lens surfaces, remove dust using a soft brush or compressed air (cans available at your local electronics store). For removing finger marks or grease, soft cleaning cloth or lens tissue lightly moistened with cleaning solution (85% petroleum ether and 15% isopropanol) should be used. For cleaning the objective optics, use Methanol. Observe sufficient caution in handling Methanol. Place the objectives and/or eyepieces on a dust- free surface (e.g. aluminum foil). All other optical components to be cleaned should be as accessible as possible.

3.. Blow all loose dust particles away with compressed air or mini dust blower.

4. Remove all water-soluble dirt with distilled water. If this is unsuccessful repeat using a solution of diluted hand soap liquid. Remove any remaining residue with a dry cotton swab.

5. To remove oil, use a solution of diluted hand-soap liquid initially. If this does not produce a satisfactory result, repeat the cleaning using a solvent (Optical Cleaning Solution 85% petroleum ether and 15% isopropanol).

6. Grease must always be removed using a solvent.

7. Cleaning is achieved by using a spiral motion from the center to the rim. Never wipe using zig-zag movements as this will only spread the dirt. With larger optical surfaces (e.g. tube lenses) the spiral motion starts initially at the rim before moving to the middle and is then followed by a center to rim cleaning motion. Normally several spiral wipes are recommended.

We recommend pure, volatile petroleum ether or Optical Cleaning Solution as explained in point 3 above.

zig-zag motion (X) spiral motion ( )

Wipe using a spiral movement. Do not use a zig-zag motion!

2. Cleaning of painted surfaces : Avoid the use of any organic solvent ( e.g. thinner, xylene, ether, alcohol etc.) for cleaning of painted surfaces of the instrument. Painted surfaces can be cleaned with a very lightly moistened micro fiber cloth. Loose dust and other dirt particles can be removed using a soft bristle brush used exclusively for this purpose.
