Blazed Holographic Gratings

Spectrum Scientific is one of the few companies in the world to offer a blazed holographic diffraction grating. A blazed holographic grating has had the sinusoidal profile transformed into a ‘saw tooth’ profile. This saw tooth profile increases the efficiency of the diffraction grating over the wavelength region of interest without increasing the stray light.

Spectrum Scientific uses a proprietary blazing technique which creates a blazed grating that demonstrates considerably lower stray light with equivalent or better efficiency when compared to ion-etched gratings. Currently this technique is limited to a blaze region of 200-300mm.

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.

Spectrum Scientific offers a range of standard gratings. If we do not have a grating that meets your requirement, please contact our sales department as new gratings are manufactured on a regular basis.
