GR2550-30035 25 x 50 x 9.5 mm Hard Glass (Pyrex) Mid-IR Ruled Reflective Diffraction Grating; 300 Grooves/mm Coated
The GR2550-30035 is a rectangular Mid-IR Ruled Reflective Diffraction Grating, manufactured by Thorlabs. This grating, designed for use in the mid-infrared spectrum, boasts a blaze wavelength of 3500 nm and a groove density of 300 grooves per millimeter. The blaze angle, which significantly influences the grating's efficiency, is set at 26.5 degrees.
The grating's physical dimensions are 25 x 50 x 9.5 mm, with a thickness of 9.5 mm. It is made from hard glass, specifically Pyrex, known for its excellent chemical resistance and durability. The grating is coated on the front side with a coating identified as THo GR1325-30035, enhancing its performance in specific applications.
The grating's orientation vector is along the x-axis, and it operates in the -1st order. The dispersion, a critical parameter for spectroscopic applications, is 2.86 nm/mm. The grating's inner and outer radii are both zero, indicating a flat grating surface.
