2. Absorption filter system (fig. 22, 23 and 24)
The absorption filter system (fig. 22) consists of a
filter lantern (2) with 7 optical filters (3), which
are inserted next to each other, and an outer
cylinder of special UV glass (Suprax) (4).
Different spectral energy distribution va-
lues can be obtained by varying the op-
tical filters and the outer cylinder (see
fig. 25 as an example).
