Products: Gratings

image of Gratings

Princeton Instruments monochromators and spectrographs use diffraction gratings as the optical element which separates (disperses) polychromatic “white” light into individual wavelengths (colors).

When polychromatic light encounters the grating it is dispersed so that each wavelength reflects from the grating at a slightly different angle. Dispersed light is then reimaged by the monochromator or spectrograph so that individual wavelengths (or a desired band of wavelengths) can be directed to a detection system or sample.

Available Coatings for Gratings

Princeton Instruments gratings are supplied with a bare aluminum coating, which offers approximately 85-90% reflectivity from the UV through the NIR, increasing to ~98% in the SWIR and MIR.

We also offer protected gold coating on gratings which will increase the efficiency of a grating by up to 15% in the NIR. Gold is unsuitable for wavelengths shorter than 600 nm. Refer to reflectance information below.
