The RW25-20-3UV is a rectangular flat window, a type of optical element designed to provide protection while maintaining optical transmission. This specific model, sourced from Laser Components, measures 20 x 25 mm in width and length, respectively, with a thickness of 3 mm.
The window is made from UVFS, a material with the material ID UVFS Mal-1965. This material is particularly suitable for applications involving ultraviolet light, as indicated by the "UV" in the name. The wavelength for this component is 632.8 nm, which is within the visible light spectrum.
The window is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be beneficial in applications where maintaining the original optical properties of the material is crucial.
