This is a G390136525 optical flat window, a high-quality component designed for use in a wide range of optical systems. The window is rectangular in shape, with dimensions of 15 x 20 mm, and has a thickness of 2mm. It is made from N-BK7, a type of borosilicate glass known for its excellent optical properties, including a low coefficient of thermal expansion and high homogeneity. This particular window is sourced from Qioptiq Photonics, a leading manufacturer of precision optics.
The window features anti-reflection coatings on both the front and back surfaces. These coatings, identified as 'qio bbar arb2nirnbk7', are designed to reduce surface reflections and increase transmission within the wavelength range of 725-1050nm. This makes the window ideal for use in systems operating in the near-infrared spectrum.
The window is classified as a 'flat window', indicating that its surfaces are parallel and flat. This is a 'thin lens' shape, meaning that the thickness of the window is significantly less than its other dimensions. This shape is often used in optical systems where the window's primary function is to protect other optical elements or to provide a physical barrier, rather than to refract or focus light.
