OPSQ-130C18-1-5 130 mm Dia. UVFS Round Optical Parallel Flat Window; t=18 mm Uncoated

The OPSQ-130C18-1-5 is a high-quality optical window from OptoSigma, a leading vendor in the optical industry. This window, designed for use in a variety of optical systems, is a flat, circular shape with a diameter of 130 mm and a thickness of 18 mm.

The window is made from UVFS, a type of synthetic fused silica material with the material ID "uvfs mal- 1965". This material is known for its excellent optical properties, making it an ideal choice for applications that require high precision and clarity.

The window is designed to be used at a wavelength of 588 nm, making it suitable for a wide range of optical systems and applications. It features a thin lens shape, which contributes to its high performance and versatility.

Notably, this window is uncoated, meaning it does not have any additional layers or treatments applied to its surface. This can be beneficial in certain applications where a natural, unaltered optical surface is required. However, it's important to note that uncoated windows may be more susceptible to environmental factors such as dust, dirt, and moisture, so they may require more frequent cleaning and maintenance.
