When replacing a filter, make sure that the direction of the arrow on the filter glass and the direction of the beam are identical. Put in the filter glass accordingly. If you can read the print on the
filter glass when the beam comes from the bottom, it is inserted correctly.
Use only framed or black filters and insert them flush to avoid scattered light.
Replacing filters of a standard filter carriage
The filters of the standard filter carriages can be replaced using the following
procedure:
1. Remove the filter carriage from the instrument.
2. Place the filter carriage on a clean flat surface.
3. Using a wooden or rubber rod (ensure that the ends are rounded so that the
corners do not scratch the filters) carefully push the filter and retaining ring
out of the filter carriage.
4. Turn the filter carriage over and insert the new filter and the retaining ring.
General Rules for positioning the filters:
• Filters must be inserted into the slides so that the light hits the top of the writing first.
• For filters with an arrow on the side, the light must hit the top in the direction of the arrow.
• In Sunrise™ instruments, the light comes from the right side and goes through the filter toward the left.
5. Carefully push the filter and retaining ring into the filter carriage, using a wooden or rubber rod.
