OPSQ-40C06-P 40 mm Dia. UVFS Round Optical Parallel Flat Window; t=6 mm Uncoated

The OPSQ-40C06-P is a high-quality optical window manufactured by OptoSigma, a leading vendor in the optical industry. This window, designed for use in various optical systems, boasts a 40 mm diameter and a thickness of 6 mm, making it suitable for applications requiring a larger aperture and robust construction.

The window is made of UVFS, a synthetic fused silica material with the designation "UVFS mal- 1965". This material is known for its excellent optical properties, including low optical absorption, high transmittance, and chemical resistance. The 6 mm thickness ensures mechanical stability and rigidity, making it less susceptible to deformation or damage during handling and installation.

The OPSQ-40C06-P is designed as a flat window, which is ideal for applications where minimal optical distortion is required. Its "Thin Lens" shape further reduces the risk of aberrations and ensures efficient light transmission.

Notably, this window is uncoated, which means it does not have any additional anti-reflective or protective coatings. While coatings can enhance performance in specific applications, an uncoated window provides a cost-effective solution for general-purpose use. It is essential to consider the wavelength of operation, which, in this case, is 588 nm.
