1.1.4 Components of the Exposure
Optics
The components of the optical system are depend-
ing on the used lamp house system.
The UV400, UV300, and UV250, exposure optics
are similar in design. The optical system consists of
an exposure lamp, ellipsoidal mirror, cold light mir-
ror
fly’s eye lens, condenser lenses, lens plates, turn-
ing
mirrors and a front lens as shown in the adjacent fig-
ure.
The following lamp houses are available:
•LH350
• LH1500/1000
•LH5000

Also orientation of lenses and the cold
light mirror must not be changed.
