OPSQ-50S05-4-5 50 x 50 mm UVFS Square Optical Parallel Flat Window; t=5 mm Uncoated

The OPSQ-50S05-4-5 is a high-quality optical window manufactured by OptoSigma, a leading vendor in the field of optical components. This specific model boasts a 50 x 50 mm square base shape, making it suitable for a wide range of applications that require a robust and transparent optical element.

The window is designed with a thickness of 5 mm, providing excellent structural integrity and resistance to external pressures. This makes it an ideal choice for applications where durability is a critical factor. Despite its thickness, the window maintains excellent optical properties, thanks to its high-quality UVFS material.

UVFS, or Ultraviolet Fused Silica, is a type of synthetic fused silica known for its exceptional optical clarity and resistance to thermal shock. This material is particularly suitable for applications involving ultraviolet light, as it exhibits low optical absorption in this region of the spectrum. The UVFS material also offers excellent chemical resistance, making it suitable for use in harsh environments.

The OPSQ-50S05-4-5 is uncoated, meaning it does not have any anti-reflective or other surface coatings. This can be advantageous in certain applications where coatings may introduce unwanted optical effects or may be susceptible to damage. However, it's important to note that uncoated windows can have higher reflectivity than coated ones, which may need to be considered in the design of the optical system.

This window is designed to operate at a wavelength of 588 nm, although its UVFS material ensures broadband transparency across a wide range of wavelengths. It features a flat geometry, which is beneficial in applications where minimal optical distortion is required.
