Holographic Diffraction Gratings with Dispersion @ 500 nm (nm/mr) 0.5
Holographic Diffraction Gratings
These replicated holographic diffraction gratings are produced on soda lime glass substrates from high quality holographic master gratings and are intended for use in spectrometers and monochromators where cost and low stray light are of primary concern. They exhibit a flatter response due to their sinusoidal groove profile.

Pulsed 350 milli-joules/ cm2 @ 200 n sec.
CW 40 watts/cm2
Pulsed 3.5 joules/ cm2 @ 200 n sec.
CW 80 watts/cm2
Pulsed 3.5 joules/ cm2 @ 200 n sec.
CW 250 watts/cm2
For continuous high power applications.
Available with either P-type or CW-type construction for higher damage threshold performance holographic diffraction gratings can also be produced on substrates with a lower coefficient of thermal expansion (CTE) for better stability. No damage threshold minimums apply to diffraction gratings with an overcoat.
Optometrics develops hybrid grating and optical filter for holographic weapons sight.
