GT25-12 25 x 25 x 3 mm B270 Glass; Visible Transmission Grating; 1200 Grooves/mm Coated
The GT25-12 is a high-quality transmission grating offered by Thorlabs, designed for use in the visible light spectrum with a central wavelength of 588 nm. This grating, measuring 25 x 25 x 3 mm, is made from B270 Schott glass, a material known for its excellent optical properties.
The grating features 1200 grooves per millimeter, providing high resolution and efficiency. The blaze angle is 36.9 degrees, optimized for use in the visible light spectrum. The orientation vector is along the x-axis (1, 0, 0), and the grating side is the back, indicating the side of the grating where the grooves are located.
The GT25-12 comes with a coating on the front side, specifically the THo GT13-12 coating. This coating enhances the grating's performance and durability. The grating's geometry is rectangular, with a width of 25 mm, a height of 25 mm, and a depth of 3 mm. The inner and outer radii are both zero, indicating a flat grating surface.
According to Thorlabs' website, the GT25-12 is currently in stock, making it readily available for immediate use. The product's web link is provided for easy reference and further information.
