Abstract
A high-resolution optical spectrometer with multiple diffractive optical elements operates under broadband light and enables spectral splitting with 3D diffractive optical elements. Diffractive optical elements are used to provide concentration of light as well as spectral splitting. Depending on the application, the high-resolution optical spectrometer operates with a reflection or transmission diffractive optical element. The number of operating wavelengths, spectral resolution, and operating bandwidth of diffractive optical elements are flexible depending on application.
Claims10
An optical spectrometer high spectral resolution, comprising:
- a light source forming the light beam,
- entrance optical elements through which the light beam passes and which make the light beam suitable for proper operation of the spectrometer,
- focusing and guiding optical elements, which are used to focus and direct the light beam,
- diffractive optical elements designed for each wavelength, reflecting or transmitting the light beam coming out from the focusing and guiding optical element,
- a detector where the light beam reflected from or transmitted through the diffractive optical elements reaches,
- a data collector and controller that collects data and controls the system
- a moving part on which the diffractive optical elements are positioned.
