53-*-291E 91.7 g/mm Echelle Grating with 58.9° Nominal Blaze Angle

The 53-*-291E 91.7 g/mm Echelle Grating is a high-quality optical component sourced from MKS/Newport. This grating is designed with a rectangular base shape, featuring dimensions of 25 mm in width, 50 mm in height, and a thickness of 6 mm. It has no inner or outer radius, making it suitable for a wide range of applications.

The grating boasts a groove density of 91.7 g/mm and a nominal blaze angle of 58.9°. The blaze angle is a critical parameter in grating design as it significantly influences the grating's efficiency. In this case, the 58.9° blaze angle is optimized for use in the visible light spectrum, specifically at a wavelength of 588 nm.

The grating is designed for use in the eighth order, and the grating side is the front side. The orientation vector is along the x-axis, providing a clear direction for its installation and use. The grating is made of soda lime ru clear material, ensuring durability and clarity.
