GH25-12U 25 x 25 x 6 mm Borofloat33 Reflective Holographic Grating; 1200 Grooves/mm Coated

The GH25-12U is a reflective holographic grating from Thorlabs, measuring 25 x 25 x 6 mm. This grating is crafted from borofloat33, a glass-ceramic material known for its high thermal shock resistance and low thermal expansion coefficient.

The grating features a high groove density of 1200 grooves per millimeter, which contributes to its dispersion of 1.22. The orientation vector is along the x-axis, and the order is -1. The grating side is the front, and it is coated with a specialized coating, THo GH13-12U, which enhances its reflective properties.

This grating is designed to operate at a wavelength of 588 nm, making it suitable for a range of applications that require precise wavelength control and dispersion.
