89-640 25 mm Dia. UVFS Wedge Prism; t=3 mm UVFS Wedge Prism; t=3 mm UV-VIS 250-700nm

The 89-640 is a 25 mm diameter Wedge Prism, specifically a UVFS (UV Fused Silica) Wedge Prism, sourced from Edmund Optics. This prism is characterized by its 3 mm thickness and features a wedge angle of approximately 0.091188 degrees. The material used for this prism is UVFS, which is a type of fused silica, and it is coated with a UV-VIS standard curve coating on both the front and back surfaces.

The UVFS material, also known as UV-grade fused silica, is highly transmissive in the ultraviolet, visible, and near-infrared regions of the spectrum, making it ideal for applications that require high transmission in these wavelength ranges. The UV-VIS standard curve coating enhances the prism's performance by reducing surface reflections and increasing transmission.

This prism is designed to operate at a wavelength of 355 nm, making it suitable for various applications that use this wavelength, such as laser systems or UV spectroscopy. The circular shape of the prism allows for versatile use in various optical systems.

The 89-640 is currently in stock and available for purchase through the Edmund Optics website, as indicated by its "Valid - in stock" weblink status. This prism is a reliable and high-performing option for those in need of a UVFS Wedge Prism for their optical system.
