2.6.1

Switch on the Transmitted-Light Halogen Illuminator

☞

Normally, the position of the A/D illumination converter (1-5/13 or 2-7/4) is of no importance

with the Axiolab A.

Only if the transmitted-light illumination is a standard feature or has been subsequently

installed, the A/D converter will have the following functions:

• the power supply for the reflected-light halogen illuminator is switched on in the upper,

pressed position of the converter.

• in the lower, pressed position of the converter, the power supply for the transmitted-light

illuminator is switched on.

To change to transmitted-light operation, press the A/D converter (1-5/13) at the rear of the Axiolab A

into the lower position.

The functions of the on/off switch (1-5/28) and the "illuminance" control (1-5/27) are retained,

regardless of the position of the AD converter A/D (1-5/13) (see section 1.5).

Equipment of Filter Slider

• Equip filter slider (2-5/3) with the filters (2-5/2)

required for the relevant microscopy technique,

e.g. with

− neutral-density filter N 0.06

(6% transmission)

− neutral-density filter N 0.25

(25% transmission)

− conversion filter 3200...5500 K for use of

daylight color film

− narrow-band interference filter, e.g. for

contrast enhancement

Insert equipped filter slider in the compartment

until it click-stops in the relevant position in the

reflected-light illuminator (2-5/1).

The filter diameter is 32 mm.
