  • Patent number: 10295765
    Abstract: A photodiode package is disclosed that includes a TO-Can style body with an exposed sensor cavity that eliminates the necessity of an encapsulant dispensing process. The TO-Can body of the photodiode package includes an integrated coupling member to allow for coupling to a ROSA housing without an intermediate member. The photodiode package includes a base portion with a cylindrical wall portion that extends therefrom to form an optical coupling cavity. A surface of the base portion provides at least one mounting surface within the optical coupling cavity for coupling to a photodiode chip. The cylindrical wall may function as an integrated coupling member and may be used to directly couple the photodiode package, e.g., without an intermediate cap/ring, into a socket of a ROSA housing. The base portion and cylindrical wall may be formed from a single piece of material, or from multiple pieces depending on a desired configuration.

    Abstract: A light engine has a light source front surface that emits non-collimated light. A collection lens collects the non-collimated light and provides incompletely collimated light. A collimating lens receives the incompletely collimated light and provides a collimated image. A non-orthogonal polarizing filter receives the collimated image and passes a polarized portion of the collimated image as a direct component of the polarized light engine image. The non-orthogonal polarizing filter reflects a recycled image back to the front surface. The non-orthogonal shape of the polarizing filter is selected according to the pattern of light on the light source front surface.
