Blazed Gratings BG25-300-300

Blazed gratings achieve the transfer and concentration of light energy from the zeroth order to a specific spectral order through groove etching, serving as dispersive elements widely used in spectroscopy-related fields.

LBTek blazed gratings are replica gratings with first-order diffraction efficiency exceeding 60% at their blaze wavelength. The series features aluminum film coating, with options selectable based on blaze wavelength, blaze angle, or groove density.
