Holographic Diffraction Gratings

holographic-diffraction-grating--efficiency-curve — Sample Efficiency Curve – 1000 UV Holographic Grating

High-Quality 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.

Damage Thresholds

Available with either standard 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 for better stability. No damage threshold minimums apply to diffraction gratings with an overcoat.

Standard

Pulsed 350 milli-joules/ cm² @ 200 n sec.
CW 40 watts/cm²

CW-Type

Pulsed 3.5 joules/ cm² @ 200 n sec.
CW 250 watts/cm²

For continuous high power applications.
