Retro-reflecting optical unit means a combination of optical components producing retro-reflection.
Retro-reflecting optical unit means a combination of optical components producing retro-reflection.
Retro-reflecting devices may consist of a combined retro-reflecting optical unit and filter, which must be so designed that they cannot be separated under normal conditions of use.

a brief description giving the technical specifications of the materials of which the retro-reflecting optical unit is made
In one embodiment, a catadioptric optical system (800) includes a first catadioptric element (801) and a second catadioptric element (803).
The optical system may be a catadioptric optical system having one or more lens elements.
The optical system may be a cathadioptric optical system having one or more lens elements.
The optical system may be a catadioptric optical system having one or more lens elements.
This time, one of many, I was to use a kataphatic approach.
Illumination can enter the catadioptric optical system using an auxiliary beamsplitter or mirror, or through the catadioptric group at any angle from 0 to 85 degrees from vertical.
The catadioptric optical reduction system provides a relatively high numerical aperture of 0.7 capable of patterning features smaller than 0.25 microns over a 26 mm x 5 mm field.
