B) with high-performance lamp:
Adjustment of the microscope and the microscopic
image is done in the same way described for the
halogen lamp.
⚪ Turn on the desired high-performance lamp.
⚫ Turn the rotary prism for light from the HBO lamp
⚫ When working with mirror housing 4, switch exciter
filter to white dot. With mirror housing 2, red dot
⚫ Turn on collector for high-performance lamp
⚪ Use neutral density filters for transmitted-light
⚫ With the appropriate high-performance lamp
collector, evenly illuminate the field
Brightfield immersion condenser:
N.A.: 1.30
Free working distance: 0.42mm
Use: for all lenses from 4x to 100x.
When working with the 4x objective, the condenser
turret is set on 4. Suitable for all contrast methods.
Brightfield dry condenser:
N.A.: 0.90
Free working distance: 0.29mm
Use: for all lenses from 4x to 100x.
When working with the 4x objective, the condenser
turret is set on 4
Recommended for all investigation methods where the
immersion condenser NA=1.30 cannot be used and
immersion is not desired. Suitable for all contrast
methods except for contrast fluorescence.
Large field condenser:
Aperture: 0.12
Free working distance: 43.7mm
Use: for all objectives from 2.5x to 10x.
The condenser is permanently mounted in the turret.
When working with this condenser and with objectives
below 4x, the supplementary optics lever (if available)
in the microscope base plate is set to LP. To sharpen the
field diaphragm, the condenser is lowered first with
coarse feed to the lowest position, then lowered with
fine adjustment. The upper condenser turret is rotated
so that the mark LP is toward the observer, and for no
filtering, the lower condenser turret is rotated so the
white edge mark is under the LP
