Brightness adjustment

A 12 V 100 W transformer is built into the stand for stepless regulation of brightness with the brightness control.

Coarse and fine control

The coarse and fine focus control allows fast and precise focusing of the microscope image. Focusing is done by a vertical movement of the objective nosepiece. The vertical movement range is 9 mm.

Mains switch

The mains switch is used for switching the microscope power supply on and off.

Incident light fluorescence device

The variant with incident light fluorescence device contains the integrated fluorescence axis and the lamp mount or a mirrorhousing for adaption of a second lamphousing. The fluorescence stand also comprises the fluo- rescence module which takes 4 filter cubes. This module is also available as a motorised va- riant under the name RF4-mot module (see Technical Description).

Aperture diaphragm

The aperture diaphragm determines the resolution, field depth and contrast of the microscope image. The best resolution is achieved when the apertures of the objectives and the condenser are roughly the same.

n. b.:

The aperture diaphragm in the illumination light path is not intended for adjusting the brightness of the image. This should only be done by turning the brightness adjustment knob or using the neutral light damping filter.

Condenser

The condenser is a lens system through which the light is collected and focused on the specimen underneath. The condenser is de- signed to utilise the numerical aperture of the objective.

Condenser height adjustment

The markings on the transmitted light illumi- nation column indicate the height settings of the different condensers.
