UV Transmission Gratings

Edmund Optics, optical components provider, has introduced new UV transmission gratings that feature a UV grade fused silica substrate. They are relatively polarisation insensitive and so resistant to alignment errors. Models are offered with 300, 600, 830 and 1200 grooves/mm in three different sizes, including 12.7, 25 and 50mm square. They are available in multiple diffraction angles. UV transmission gratings are a method of dispersing light for fixed grating applications in the 250-450nm wavelength range. Manufactured from a UV grade fused silica substrate, the gratings are designed for the incident light to strike the UV gratings' coarse groove spacing. From there it is then dispersed to the opposite side of the grating at a fixed angle. As the groove spacing increases, the diffraction angle decreases.
