This is a G340332331 rectangular metallic mirror, manufactured by Qioptiq Photonics. The mirror measures 60 x 85 mm and has a thickness of 8mm, making it a thin lens type. The mirror's base shape is rectangular, and it is made of borofloat33, a type of glass known for its high chemical resistance and low thermal expansion coefficient.
The mirror is coated with a front aluminized coating, specifically 'qio al ralvis aoi 400-700nm 45', which is designed for use in the visible light spectrum, specifically between 400 and 700nm. This coating is applied at a 45-degree angle, which is typical for mirrors to achieve total internal reflection.
The mirror's geometry is defined by its base shape, which is rectangular, and its dimensions. The 'd' parameter represents the thickness of the mirror, which is 8mm in this case. The 'b' parameter is the base length, which is 60mm, and the 'l' parameter is the base width, which is 85mm.
The mirror is currently in stock and available for purchase on the Qioptiq Photonics website. For more information, you can refer to the provided weblink.
