SZ-Ill

The

model SZ-Ill is .an advanced model of

which was

revolut-

ionary product which adopted the zooming ma~nificotionmechanism, for

the first time in the world in a stereoscopic microscope,. rapidly expanding

its range of utilization such as in the classification of plants, anatomy

animals, or in assembly and inspection

modern electronic products

and precision instruments.

No outfocusing effect will be experienced and any desired magnifica-

tion can be obtained within the area

the

xoom

ratio

5.7.

Further,

there is no "image fade away" when changing magnifications as in the

case of any former microscope.

Doubtlessly this will greatly increase the working efficiency.

set

of Model SZ-Ill is completely equipped with accessories assuring its versatile

utilization. This may be called the definitive product of stereoscopic

microscopes.

ZOOMING VARIATION

SYSTEM

This system is composed of

sets of lenses

consisting of

groups

performed by zooming these

lenstr and

changing the focal length of the objective. In case of the magnification change from

higher one, the lower lens group (1st tens

group)

rises

to the

middle

and then comes down.

FOCUSING MECHANISM

Focusing is performed by:

(1)

Sliding the body on the pillar until rough focus is

attained and

(2)

making fine adjustment by the focusing knob. The range of movement

by the focusing knob is

55mm

(up

and

down).

PARFOCALITY

ADJUSTMENTS

The Olympus Model SZ-I11 is designed to de ~arfoeaIin both right and left

eyepieces on all magnification settings at the standard distance of distinct vision

(250

mm). However, each person has

different distance of distinct vision from the other.

obtain satisfactory parfocality with

the

Model

SZ-111,

follow the below described

procedures when focusing the image of specimen.

(1)

Set the both (right and left) diopter rings at

'0'.

(2)

Set the magnification drum at

'4'.

(3)

Focus the image by means of the focusing knob.

(4)

Set the magnification drum

'0.7'.

(5)

the image is out of focus, perform focusing by adjusting the diopter ring(s)

......

right or left, or both, as required.

NOT

perform focus adjustment with the focusing knob.

(6)

Once again set the magnification drum at

'4'.

the imagc is still out of focus, adjust the diopter ring(s) (right or left, or

both) to bring the image in focus.

NOT

perform focus adjustment with the focusing knob.

(7)

Now your Model SZ-I11

has

been adjusted to

parfacal at your own distance

of distinct vision. Hence, re-adjustment

microscope

when

you

switch from

one magnification to the other is not necessary.
