A wavelength de-multiplexing system that receives a wavelength multiplexed signal and generates electrical signals corresponding to the optical signals is disclosed. The optical receiver module includes a lens, a lens unit, and an optical de-multiplexer (O-DeMux). The lens converts the wavelength multiplexed signal into a quasi-collimated beam. The lens unit narrows a diameter of the quasi-collimated beam. The O-DeMux de-multiplexes the narrowed quasi-collimated beam coming from the lens unit by wavelength selective filters (WSFs) each having optical distances from the lens unit different from each other.

New systems and methods are described for maintaining a desired steady state temperature differential between two objects that may otherwise undergo heat transfer to restore thermal steady state. In one application, a cooling microscope assembly and its use with conventional optical microscopes are described for achieving super-resolution imaging. The assembly allows for the high resolution imaging of samples at cryogenic temperatures while maintaining the temperature of the objective lens above freezing by employing circulation systems and a coupling fluid between the sample and objective lens.

Optical systems including an image surface, a stop surface, a partial reflector disposed between the image surface and the stop surface, a reflective polarizer disposed between the stop surface and the partial reflector, and a quarter wave retarder disposed between the reflective polarizer and the partial reflector are described. The reflective polarizer is convex along two orthogonal axes. The reflective polarizer may be a thermoformed multilayer reflective polarizer.

An optical stack includes first and second lenses, a partial reflector, a reflective polarizer, and a retarder. The reflective polarizer is curved about two orthogonal axes and includes at least one layer that is substantially optically uniaxial at at least one location. An optical system includes the optical stack disposed between an image surface and an exit surface. The optical system is configured such that substantially any chief ray transmitted from the image surface to the exit surface is first incident on the reflective polarizer at an angle of incidence less than 30 degrees.

The reflective polarizer is curved about two orthogonal axes.

A detector device is designed to capture light and to generate electrical signals. The detector device includes a housing and a detector disposed in the housing so as to be moveable at least partially in the housing and with respect to the housing. The detector device is useable in a detection system and/or in a microscope.
