Sample Efficiency Curve – 120/12µ Ruled Diffraction Grating

These replicated diffraction gratings are produced from high quality ruled master gratings and are intended for use in spectrometers and monochromators where cost and high efficiency are of primary concern. Ruled diffraction gratings have a higher peak efficiency than holographic diffraction gratings and a sharper spectral response around their blaze wavelength. Due to their “sawtooth” groove profile, they have a relatively sharp peak around their blaze wavelength.

Applications like fluorescence excitation, analytical chemistry, life sciences, telecom, physics, education and space sciences – centered around a narrow wavelength range – benefit from a ruled diffraction grating blazed at that wavelength.

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.
