Abstract: A device for creating a panoramic field of view comprises a first light passing incident surface which is a cylinder surface and a second incident surface which is a mirror surface onto which light passing through the first surface impinges. A third incident surface onto which light from the second incident surface impinges is provided and the third incident surface being an aspherical transmission surface. A recollimating element for presenting a pupil plane depiction of a panoramic field of view is also provided. Various embodiments may include single or double lens devices with a second lens provided for the purpose of recollimating light.

Abstract: An optical spectrometer system has a central axis, a detector having a detector surface disposed at one end of the system and located at a focal plane of the optical spectrometer system. A cold stop is associated with the detector for permitting entrance of target source radiation onto the detector surface while blocking background radiation from surroundings. A cooling device is coupled to the detector for cooling it and the cold stop to a predetermined low temperature. A flat plate is provided and has an spectrometer slit formed in it, the plate having a flat surface facing the detector, the flat surface being coated with a highly reflective, low emissivity material. Fore-optic focusing lenses or mirrors are located in front of the flat plate for focusing radiation onto the slit on the flat plate between the fore-optic focusing and the collimating lenses. The collimating lenses between the flat plate and the cold stop collimate the light from the slit and form a pupil at the cold stop. Both the fore-optic focusing lenses and the collimating lenses are designed such that the space between them is telecentric. This allows the use of an uncooled flat high reflective slit body that has very little self emission yet it does not reflect the background thermal radiation from the spectrometer cavity into the cold stop and impinge on the detector.

Abstract: An optical sensor head (400) for providing an optical sensor with a hyperhemispherical field of view is disclosed. The optical sensor head (400) includes first and second lenses (430 and 440), each of the lenses (430 and 440) having a planar surface (434 and 444) and a convex surface (432 and 434). The sensor head (400) further includes a film (420) positioned between the lenses (430 and 440) for splitting the light beams impinging thereon.
