Microprism

A microprism is a very small prism, typically with dimensions in the micrometer range. These tiny optical components are often manufactured using microfabrication techniques similar to those used for integrated circuits. Their small size allows for integration into compact optical systems, micro-optics, and optoelectronic devices.

Microprisms function on the same principles as larger prisms, namely the refraction of light as it passes from one medium to another with a different refractive index. This refraction can be used to deviate a light beam, split a beam into its constituent wavelengths (dispersion), or change the polarization state of light. Due to their miniature scale, microprisms are particularly useful for manipulating light at a microscopic level.

Applications of microprisms are diverse. They can be found in micro-spectrometers for chemical analysis, in miniature cameras and imaging systems, and in optical sensors. They are also employed in advanced display technologies and in devices for optical signal processing. The ability to create arrays of microprisms allows for parallel optical processing and the formation of complex optical surfaces. Research continues into new materials and fabrication methods to further enhance the capabilities and applications of microprisms in various scientific and technological fields.
