This is a 41-048 reflective ruled diffraction grating, sourced from the reputable optical components vendor, Edmund Optics. The grating, which is rectangular in shape, measures 12.5 mm in width, 25 mm in length, and 9.5 mm in thickness, making it suitable for a variety of optical applications.
The grating is made of soda lime float glass, a common material in optical components due to its excellent optical properties and durability. The glass is clear, allowing for maximum light transmission.
The grating has 1200 grooves per millimeter, with a blaze wavelength of 400 nm. This high groove density allows for efficient diffraction of light, making the grating ideal for applications such as spectroscopy and beam splitting. The blaze angle is 13.88 degrees, which is optimized for the specified blaze wavelength.
The grating is coated with bare aluminum on the front side. This coating enhances the grating's reflectivity, making it more efficient in diffracting light. The grating side is the front side, meaning the aluminum coating is applied to the side of the grating where the incident light first hits.
The grating is currently in stock and available for purchase. For more information, please refer to the provided weblink.
