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. |
