Low noise optical housing
First Claim
1. An optical housing comprising:
- a substrate having a reflective side and an absorptive side;
a generally planar base portion of said substrate; and
a protruding cover portion of said substrate, said cover portion defining a pocket on said absorptive side;
said substrate having an open position with said base portion distal said cover portion and a closed position with said base portion proximate said cover portion, said substrate configured to enclosed a detector within said pocket in said closed position;
wherein said base portion defines an aperture generally centered within said base portion and aligned with said detector in said closed position so as to pass light through to said detector.

Abstract
Aspects of the invention include an optical housing including a substrate having a reflective side and an absorbing side. The substrate has a generally planar base portion and a protruding cover portion. The cover portion defines a pocket on the absorbing side. The substrate has an open position where the base portion is distal the cover and a closed position where the base portion is proximate the cover. The substrate is configured to enclosed a detector within the pocket in the closed position. The base portion defines an aperture generally centered within the base portion and aligned with the detector in the closed position so as to pass light through to the detector.
