OPSQ-50C08-1-5 50 mm Dia. UVFS Round Optical Parallel Flat Window; t=8 mm Uncoated

The OPSQ-50C08-1-5 is a high-quality optical window manufactured by OptoSigma, a leading vendor in the field of advanced optical components. This window, designed for use in a variety of optical systems, boasts a 50 mm diameter and a thickness of 8 mm, making it suitable for applications requiring a larger aperture and robust construction.

As a flat window, it is designed to maintain the collimation and direction of incident light without introducing any additional optical power or distortion. This makes it ideal for use as a protective barrier, a mounting surface for other optical elements, or as a simple beam-shaping component.

The window is made from UVFS, a type of synthetic fused silica. This material is known for its excellent optical properties, including high transparency across a wide range of wavelengths, low autofluorescence, and high resistance to thermal shock and chemical etching. The UVFS material also offers a low coefficient of thermal expansion, ensuring dimensional stability even in environments with varying temperatures.

The window is uncoated, meaning it does not have any additional anti-reflective or protective coatings. This can be advantageous in certain applications where a broadband, unpolarized, or high-damage threshold is required. However, for applications where specific reflection or transmission characteristics are needed, additional coatings may be applied.
