84-457 40 mm Dia. UVFS Round Protective Flat Window; t=4 mm VIS-NIR 400-1000nm
The 84-457 is a 40 mm diameter, 4 mm thick flat window made from UVFS material, specifically UVFS Mal-1965. This window is designed for use in the visible to near-infrared (VIS-NIR) spectrum, spanning 400-1000nm.
The window features a coating on both the front and back surfaces, specifically the EDM VISNIR0SP2002000 coating. This coating is designed to optimize performance in the VIS-NIR spectrum, providing excellent transmission characteristics and durability.
The window is shaped as a thin lens, making it suitable for use in a wide range of optical systems where minimal thickness and weight are desirable. The circular geometry of the window allows for easy integration into circular optical paths.
