The embodiment of the invention provides a metal wire grid polaroid and optical detection equipment. The metal wire grid polaroid comprises a transparent substrate and a metal layer arranged on the transparent substrate, wherein the metal layer comprises a first wire grid unit and a second wire grid unit, the first wire grid unit comprises a plurality of first metal strips which are arranged in parallel at intervals, the second wire grid unit comprises a plurality of second metal strips which are arranged in parallel at intervals, and the extension direction of the first metal strip is not parallel to the extension direction of the second metal strip. According to the invention, when the metal wire grid polaroid is applied to optical detection equipment, the first wire grid unit and the second wire grid unit can be arranged corresponding to a first detection unit and a second detection unit respectively, so that polarization directions of polarized light detected by the first detection unit and the second detection unit are different, one optical detection equipment can be adopted to realize detection of various polarized lights, and in the detection process, the position or direction of the detection unit does not need to be changed so as to conveniently use the optical detection equipment.
Description
technical field [0001] The present application relates to the technical field of polarizers, in particular to a metal wire grid polarizer and light detection equipment. Background technique [0002] Polarizers include absorbing polarizers and reflective polarizers. Absorptive polarizers are, for example, polarizers in which a dichroic dye such as iodine is oriented in a resin film. Reflective polarizers include wire grid polarizers, linear polarizers made of birefringent resin laminates, and circular polarizers made of cholesteric liquid crystals. However, linear polarizers and circular polarizers show low polarized light separation ability. Therefore, a wire grid type polarizing plate exhibiting a higher polarized light separation ability has been valued. The structure of the wire grid polarizer is as follows: a plurality of thin metal wires are arranged parallel to each other on a light-transmitting substrate. When the distance between the thin metal wires is sufficient...
