53-*-149E 180 g/mm Echelle Grating with 41.8° Nominal Blaze Angle

This product is a 53-*-149E 180 g/mm Echelle Grating, available from the renowned vendor MKS/Newport. The grating is characterized by its rectangular base shape, with dimensions of 25 mm in width and 50 mm in height, and a thickness of 6 mm. It has an inner radius of 0 and an outer radius of 0, indicating a flat surface.

The grating features 180 grooves, designed with a nominal blaze angle of 41.8°, which is a key factor in determining its efficiency. The blaze angle is the angle at which the grooves are cut into the grating surface, and it significantly influences the grating's performance at different wavelengths. In this case, the grating is optimized for a wavelength of 588 nm.

The grating's order is 16, which refers to the number of times the diffracted light beam repeats along the grating surface. The grating side is the front side, meaning that the grooves are etched into the front surface of the grating.

The grating is made of soda lime ru clear material, as indicated in the Material ID. However, the coating information is not provided in the item data.
