GT13-12 12.7 x 12.7 x 3 mm B270 Glass; Visible Transmission Grating; 1200 Grooves/mm Coated

The GT13-12 is a high-quality transmission grating offered by Thorlabs, a leading vendor in the field of optical components. This grating, with its dimensions of 12.7 x 12.7 x 3 mm, is designed to provide efficient diffraction of light in the visible spectrum.

The grating features 1200 grooves per millimeter, a density that allows for precise control and manipulation of light. The blaze angle of 36.9 degrees is optimized for use in the visible light range, particularly around the wavelength of 588 nanometers. The orientation vector is along the x-axis, providing a clear directionality for the grating's operation.

The grating is coated on the back side with a specialized coating (tho gt13-12) that enhances its performance and durability. The grating side is also specified as the back, indicating the side of the coating. The grating is made of B270 Schott glass, a material known for its excellent optical properties and resistance to environmental factors.

The item data provides a 'weblink status' of 'Valid - in stock', indicating that the grating is readily available for purchase. The catalog number, GT13-12, can be used to directly access the product page on Thorlabs' website for more information or to place an order.
