Your

light source

may

need to be

"centered"

if the field of

view seems unevenly illuminated.

The

centering

controls

are

located

on

the

side of the

light

source

housing at

the back end of the

vertical

illuminator. The

drawino

below

shows the location

of

the controls.

Centering

Adjustment

1. Adjust the brightness to a comfortable level with no

specimen

on the stage.

2. Loosen the screw

on the

vertical

adjustment and

while

looking into

the eyetubes, center the bulb

vertically

in the field of

view and then

re-

tighten the screw while the bulb

filament

is in the

correct

position.

While

continuing to

look into the

eyetubes, center the

bulb

filament in

the field of

view

by using

the knob

Operation

-

Brightfield

(MX7500/MX8500

series)

1. First, set

your

interpupillary

distance on the

microscope

eyetubes

by

pulling

them apart

or

pushing

them

closer

together to fit

your

eyes.

When

set correctly, one will see one

uniform

round

or

"fused"

field

of

view. Make note

of

the

distance

setting when

adjusted to

your

liking so

you

can

later repeat

the setting.

2. Adjusting the brightness

desired

is

done

with the variable

brightness

control

knob

on microscope base

(MX7500)

,

or control knob on the

front of the standalone

power

supply MXB500).

3.

Make sure the

field

iris

diaphragm on the vertical

illuminator

is

opened all

the

way open

(move

lever

to the right) to

start.

4. We recommend

that

you

initially

use a

flat,

easily

recognizable

specimen

to set

up

your

microscope.

Place that specimen

on the

stage.
