This is a 43-227 reflective grating, specifically a holographic grating, sourced from Edmund Optics. It is rectangular in shape with dimensions of 12.5 mm in width, 25 mm in length, and 9.5 mm in thickness. The grating has a bare aluminum coating on the front surface, identified as 'edm diel bare al oap' in the item data.
The grating features 3600 grooves per millimeter, making it a high-density grating. The orientation vector is along the x-axis, indicating that the grooves are parallel to the y-axis. The order of the grating is -1, which is typical for holographic gratings. The grating side is the front side, where the aluminum coating is applied.
This grating is designed for use at a wavelength of 588 nm. The material of the grating substrate is soda lime, which is commonly used in optical components due to its high transparency in the visible spectrum. The grating is currently in stock and available for purchase, as indicated by the 'weblink status' in the item data.
