Richardson Gratings 600 Grooves, 25 x 25mm, Plane Ruled Gold Reflection Grating

Product Details Optimized for use from 350-800nm (500nm) or 700-1600nm (1000nm) Available in standard sizes 12.7 x 12.7, 25 x 25 and 30 x 30mm Groove Spacing Tolerance <0.05% Custom Sizes Available Richardson Gratings High Precision Plane Reflective Gold Diffraction Gratings are gold coated versions of the Richardson Gratings High Precision Plane Ruled Reflective Diffraction Gratings. They are available with blaze wavelengths 500nm or 1000nm and optimized for use at 350-800nm or 700-1600nm respectively. These ruled gratings are characterized by a superior efficiency at their design wavelength compared with holographic gratings. Richardson Gratings High Precision Plane Reflective Gold Diffraction Gratings are an excellent choice for spectroscopy setups using silicon detectors or fiber-optic telecommunication applications for which higher reflectivity in NIR/IR spectral regions is required. Custom sizes are available on request. Note: The surface of these gratings is very sensitive and should never be touched when handling the optic. If cleaning is required, i.e. to remove dust particles, non-contact cleaning using clean compressed air is recommended.
