× Drawing Eyepiece

The 8× drawing eyepiece (444126-0000-000) is an accessory for microscopic drawing and can only be

used in combination with the binocular reflected-light tube 30°/20 H

on the Axiolab A. It contains a

beam splitter which allows the simultaneous observation of the microscope image and the drawing area.

Switch on the microscope as described in section

3.2 and set it for reflected-light brightfield

according to section 3.2.1.

• Remove one eyepiece (3-18/1) and insert the 8×

drawing eyepiece (3-18/3) in the binocular

reflected-light tube 35°/20 (3-18/2) until stop.

Swing 8× drawing eyepiece until the drawing

area (DIN A4 notepad) lying in front of the

stand appears symmetrically aligned also in the

field of view.

• Screw on the drawing eyepiece.

• Illuminate the drawing area in such a way that

it can be seen in the same quality as the

microscope image. If required, reduce the

brightness of the microscope image via the

illuminance control (3-2/7).

• A special drawing pencil is supplied to facilitate

drawing.

☞

If the image on the drawing area is too dark, an additional desk illuminator should be

installed. We would recommend the use of spotlights with a homogeneous area illumination

(dia. 250 mm).

We would also recommend you to use a support for the drawing area, which should be 20

mm thick. This is the only way to ensure that the exact distance to the drawing eyepiece is

kept.

30°/20 means a viewing angle of 30° and the maximum field number 20.
