Product Name Notes
A diffraction grating is an optical component that separates (diffracts) polychromatic (white) light into its component wavelengths. Each grating is fabricated from a highly accurate master grating that is copied...
Holographic gratings are formed by an interference fringe field of two laser beams whose standing wave pattern is exposed to a polished substrate coated with photo resist. Processing of the...
15 to 20% Efficiency Increase Over Aluminum (0.7-1.1 microns) These ruled gold-coated versions of our commercial gratings provide a 15-20% increase in absolute efficiency from 0.7-1.1 microns. This makes them...
Ideal for Flat-Field and Imaging Applications Aberration Corrected to Eliminate Astigmatism Simplifies System Design by Eliminating Need for Other Image-Forming Optical Elements Concave gratings accomplish the task of two optical...
Less Stray Light than Ruled Diffraction Gratings Improved Diffraction Efficiency Over Holographic Gratings Broad Spectral Range Our blazed holographic gratings ensure less stray light than conventional mechanically ruled gratings without...
Low Polarization Sensitivity Ideal for In-Line Configurations Transmission Gratings are designed to disperse incident light at specific angles. Angular dispersion is a function of angle of incidence and groove spacing.
