10Q20RAR.S 25.4 mm Dia. UVFS Antireflection o-Texture Surface Parallel Optical Flat Window; t=4 mm 250-550nm

The 10Q20RAR.S is a high-quality optical window, designed and manufactured by MKS/Newport. This component, with a base shape of a flat window and a circular geometry, boasts a diameter of 25.4 mm and a thickness of 4 mm, making it a robust and reliable choice for various optical applications.

The window is made from UVFS, a material with the MKS/Newport material ID of 1965. This material is specifically designed for use in the ultraviolet, visible, and shortwave infrared regions of the spectrum, making it a versatile choice for a wide range of optical systems.

The 10Q20RAR.S is coated with a new RARSAR250550 coating on both the front and back surfaces. This antireflection coating is designed to minimize reflection and maximize transmission in the 250-550 nm wavelength range, making it ideal for use in systems where high transmission and low loss are critical.

The window is designed in the shape of a thin lens, which can provide additional functionality in certain applications. It is currently in stock and available for immediate purchase, as indicated by its valid web link status.
