0.1mm
Use: In combination with the lower condenser turret,
can work with lenses 25x and 40x. There is a torus

studies.
Blocking filter slide for transmitted-light
fluorescence
The blocking filter slide is inserted from the right in
the transmitted-light optics carrier. The spring
retainer on the front of the optics carrier is pulled
slightly out and the empty slide removed. The colors
of the notch filters must be visible from the front.
Lamp shade
The lamp shade protects the observer from stray UV
light. It is magnetically attached below the body of
the microscope stand.
UV light blocking tube
The light tube is placed on the light well of the
microscope base plate and protects from UV glare.
In addition, it can be used to hold various 50mm
light filters
For an overview of the use and combination of the
exciter and blocking filters, please read the
fluorescence methods descriptions of the mirror
houses 2 and 4.
