Gratings

Grating Selection

Grating selection is a crucial part of building a monochromator. Each ruled or holographic grating is designed to diffract light most efficiently over a specific band of wavelengths.

This tool allows you to compare efficiency curves for different gratings that Sciencetech offers. These curves are for comparison purposes only [1].

[1] Only average curves are shown; for efficiency with regard to S and P polarization, please contact us.

These efficiency curves are measured in Littrow configuration. Our monochromators use different configurations, and so have some limitations in geometry that limit the wavelength range. Please contact us to verify that your chosen grating is compatible with your selected monochromator model at the desired wavelength.
