K9L/UVFS Equilateral Dispersion Prisms
Equilateral Dispersion Prisms are common dispersive optical elements featured with an equilateral triangular structure. Due to the material dispersion characteristic, the refractive index varies with wavelength, causing light of different wavelengths to refract at different angles and exit at separate positions, thereby achieving spectral dispersion.
Compared with diffraction gratings, equilateral dispersion prisms generate less stray light and eliminate higher-order diffraction issues inherent to gratings, making them a cost-effective choice for spectroscopic applications.
