Dispersion prism GCL-03013 series

equilateral

An equilateral dispersing prism has an equilateral triangle in the crosssection with the three sides of equal length. They are used for wavelength separation. A light ray is refracted twice, passing through the prism with total deviation denoted by qd top angle. Deviation is a function of refractive index, and hence wavelength. Angular dispersion is the difference in deviation for light rays having different wavelengths and varies with prism orientation.

H-ZF13 is a flint glass that offers excellent performance in the visible and NIR spectral range. It offers a high refractive index and low Abbe number, making it excellent for use in an equilateral dispersive prism. Material：H-ZF13 (CDGM) Working Wavelength：420nm-2.3μm Coating：1/4 wave MgF2 coating at 550nm for all 3 surfaces
