The OPSQ-20S05-20-2 is a high-quality optical window from the renowned vendor OptoSigma. This window, designed for use in optical systems, is a flat, rectangular shape with dimensions of 20 x 20 mm and a thickness of 5 mm.
The window is made from UVFS, a material with the material ID "uvfs mal- 1965". UVFS is a type of synthetic fused silica known for its excellent optical properties, making it an ideal choice for a wide range of optical applications.
The window is designed to operate at a wavelength of 588 nm, which is in the yellow-orange part of the visible light spectrum. This makes it suitable for use in systems that operate in this wavelength range.
Notably, this window is uncoated. While coatings can be applied to optical surfaces to enhance their performance, an uncoated window can be advantageous in certain situations. For instance, it can reduce reflection, making it ideal for applications where minimizing loss of light is crucial.
