The GH13-36U is a reflective holographic grating from Thorlabs, measuring 12.7 x 12.7 x 6 mm and featuring a high groove density of 3600 grooves per millimeter. This grating is designed for use in the visible spectrum, specifically at a wavelength of 588 nm.
The grating is made from borofloat33, a type of glass known for its high thermal shock resistance and low thermal expansion coefficient. This makes the GH13-36U suitable for use in environments with significant temperature fluctuations.
The grating is coated on the front side with a specialized coating (tho gh13-36u) that enhances its reflective properties. The orientation vector of the grating is along the x-axis, and it operates in the -1st order. The grating side is the front side, and it has a dispersion of 4.
