Sinusoidal Holographic Gratings

Spectrum Scientific’s holographic gratings are produced using interference lithography. This process results in a smooth groove surface and eliminates the periodic errors found in ruled gratings. Because of this, holographic gratings are commonly used in applications where stray light is a concern.

Sinusoidal groove profiles are the most common groove shape for holographic gratings. The grooves are symmetrical and therefore have no blaze direction. A sinusoidal grating offers a wider spectral coverage compared to a blazed grating, but has lower efficiency.

Our stock gratings are available in 12.5 x 12.5 mm and 25 x 25 mm sizes but we can supply our standard range of gratings up to 90 x 90 mm or greater.
