MSE PRO™ Equilateral SF11 Prisms with 1/4 Wave MgF2 Coating@550nm
MSE supplies offers Equilateral SF11 Prisms with 1/4 Wave MgF2 Coating@550nm. An equilateral dispersing prism has an equilateral triangle in the cross section 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.
MSE Supplies can offer a variety of optical elements, with different focal length and coating options. Please contact us for customization or bulk orders.
