The GH25-24V is a reflective holographic grating from Thorlabs, measuring 25 x 25 x 6 mm. This grating is made from borofloat33, a type of glass known for its high thermal shock resistance and low thermal expansion coefficient. The grating features 2400 grooves per millimeter, providing a high level of dispersion at 3.03.
The grating is coated with a front coating of tho gh13-24v, enhancing its reflective properties. The orientation vector of the grating is along the x-axis, and it operates at an order of -1. The grating side is the front side, and the grating is designed to work with a wavelength of 588 nanometers.
The item data provides a link to the product page on Thorlabs' website, which indicates that the grating is in stock. This suggests that the grating is readily available for purchase and use in various optical applications.
