Hoya Holmium filters are optical filters specifically designed to selectively transmit certain wavelengths of light.
They are made using a holmium-doped glass or crystal material that exhibits distinct absorption bands in the visible and infrared spectrum. Holmium filters are commonly used in spectrophotometry and calibration applications due to their well-defined absorption peaks. These filters enable precise calibration of instruments and accurate determination of wavelength accuracy. Additionally, holmium filters find applications in the field of laser technology for wavelength calibration and alignment purposes.
