Patent ID: 6985299

Claim:
An optical system comprising: a. a telecentric lens having a configuration for inducing a simultaneous transformation to a number of distinctly propagating signal beams from a first beam propagating condition into a second propagating condition and vice versa, said first propagating condition including substantially parallel first beam axes of said signal beams at a front side of said lens and including beam widths increasing towards said front side, said second propagating condition including second beam axes dispersing in direction away from a back side of said lens and including second beam widths decreasing away from said back side; and b. an optical element having a number of distinct optical surfaces and being configured and positioned with respect to said lens such that at least one of said second beam axes coincides with at least one of said optical surfaces, wherein at least one of said optical surfaces is oriented such that at least one of said second beam axes is redirected from a dispersing direction into a converging direction.
