GTI50-03A 50 x 50 x 3 mm B270 Glass; Visible Transmission Grating; 300 Grooves/mm Coated

The GTI50-03A is a high-quality transmission grating, sourced from the renowned optical component manufacturer, Thorlabs. This grating, designed for visible light transmission, boasts a robust construction, featuring a 50 x 50 x 3 mm rectangular B270 glass base, and is coated with a specialized grating surface on the backside.

The GTI50-03A grating is characterized by its 300 grooves per millimeter, offering a high level of precision and detail in light dispersion. The blaze angle is set at 31.7 degrees, optimizing its performance for the specified wavelength of 588 nanometers. The orientation vector is aligned along the x-axis, providing consistent and reliable light diffraction.

This grating is designed to operate in the -1st order, ensuring efficient light transmission and dispersion. The grating side is specified as the backside, indicating the location of the specialized coating. The coating itself is the THo GTI25-03A 1, a proprietary coating developed by Thorlabs to enhance the performance and durability of their optical components.
