Transmitted-light filter magazine
The transmitted-light filter magazine (3-1/18) can accommodate 3 swing-in neutral-density filters or the
VIS/IR filter set for attenuation of the image brightness in the field of view. Each of these 3 neutral-
density filters features graded transmission values of 1.5 %, 6 % and 25 % (viewed on the stand from
front to back), thus permitting the maximum attenuation factor of 1:4400 when used individually or in a
combination.
When several filters are combined, the transmission value is calculated as the product of the individual
transmission values in percent.
Filter slider
The 3-position or 6-position FL filter slider (1-1/7) permits dia. 18 mm filters (e.g. PINKEL-type filters) to be
inserted in the incident-light beam path. The position of the various filters in the beam path is locked via
relevant notches in the filter slider.
The filter sliders can be equipped individually. For this purpose, only the rubber retaining ring must be
removed.
Since the 6-position FL filter slider projects on the other side of the stand when pushed through, or can
be inserted from both sides, the cover attached to the left of the stand as a standard must be exchanged
for a special guiding piece, which is supplied together with the 6-position FL filter slider. The cover and
the guiding piece are just inserted in the stand opening, i.e. they are easy to mount.
