The OPSQ-20C05-4-5 is a high-quality optical window from OptoSigma, a leading vendor in the optical industry. This window is specifically designed for use in optical systems that require a flat, circular window with a 20 mm diameter and a thickness of 5 mm.
The window is made from UVFS, a type of synthetic fused silica with the material ID "uvfs mal- 1965". This material is known for its excellent optical properties, making it an ideal choice for a wide range of applications. The window is uncoated, meaning it does not have any additional layers applied to its surface. This can be beneficial in certain applications where a specific coating is not required.
The OPSQ-20C05-4-5 is designed in the shape of a thin lens, which helps to minimize optical aberrations and distortions. It is intended for use at a wavelength of 588 nm, although it can be used with other wavelengths depending on the specific requirements of your application.
