55-258 30 x 30 x 9.5 mm Float Glass; Square Reflective Ruled Diffraction Grating; 600 Grooves/mm Bare Aluminum

This optical element is a reflective grating, sourced from the renowned vendor, Edmund Optics. It is a 30 x 30 x 9.5 mm float glass with a square reflective ruled diffraction grating, featuring 600 grooves per millimeter and a bare aluminum coating.

The grating is of the reflective type, which means it reflects the incident light back towards the source. This is particularly useful in applications where the light source is nearby, such as in monochromators or spectrometers. The grating's square shape provides a larger surface area for reflection, increasing its efficiency.

The grating has a blaze wavelength of 750 nm, which is the wavelength at which it is most efficient. The blaze angle, which is the angle between the normal to the grating surface and the direction of maximum diffraction efficiency, is 13 degrees. This angle is crucial as it significantly impacts the grating's performance.

The grating's physical data includes an order of -1, indicating the diffraction order. The grating side is the front, meaning the side of the grating where the grooves are located is the incident surface.

The material of the grating is soda lime ru clear, a common material for optical elements due to its excellent transparency and durability. The coating on the front is edm diel bare al oap, a bare aluminum coating that enhances the grating's reflectivity.
