Bertrand lens

The Bertrand lens is brought in and out of

the optical path by turning

the Bertrand

lens tu rret.

The lens is in the optical path when the

indication on the turret is B.

The Bertrand lens can be focused by turn-

ing the focus turret

located under the

Bertrand lens turret.

Pin-hole knob

The pin hole can be put in or out of the

optical

path by operating

the pin hole

knob located right-hand side of the eye-

piece sleeve.

By means of the pin hole, the conoscopic

image covering the area of

10J.1m¢

on the

specimen surface (when a 100

objective

is used) can be observed.

81M"

Used

for

episcopic

polarizing

microscopy,

mounted

between the Y -PO L stand and the

intermed iate tube "P".

Nomenclature

and assembly

•

Referring to Fig, 26, assemble in the order

given.

Remove the eyepiece tube and the inter-

mediate tube "P" from the Y -POL stand.

Mount

the epi-illuminator

"M"

on the

microscope arm, positioning

the illumina-

tor nearly parallel to the arm. Clamp the

screw.

After

releasing

sufficiently

the

clamp

screw on the lamp housing, to which the

lamp bulb

(6V-20W

Halogen lamp) and

socket is attached, insert the lamp housing

into the epi-illuminator

"M" and clamp the

screw.

Connect the lamp cord to the transformer.

Place the epi-polarizer into the slot, facing

the white

index dot toward

the mirror.

[Note]

Insertion arid removal of the epi-

polarizer should be made with a

half-reflecting

mirror brought out

of the optical path.

Place the filters.

(j)

Mount the intermediate

tube "P" on the

illuminator

"M", positioning the tube with

its "Nikon"

plate faced to the operator,

regardless of the groove of the intermediate

tube "P" mount. Fasten the tube tentative-
