11-739 50.8 mm Dia. UVFS Ultrafast Flat Window; t=1 mm BBAR 1900-2200nm

The 11-739 is a high-quality flat window, designed with a base shape of a circle and a diameter of 50.8 mm. This window is part of the UVFS series, specifically identified as UVFS Mal-1965, and has a thickness of 1 mm.

This optical component is sourced from the reputable vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status. The window is designed to operate at a wavelength of 2000 nm, making it suitable for applications that require precise optical performance at this specific wavelength.

The 11-739 features a broadband anti-reflection (BBAR) coating, specifically designed for the wavelength range of 1900-2200 nm. This coating, identified as EDM BAR190022001173, is applied to both the front and back surfaces of the window. The BBAR coating reduces reflection, thereby increasing transmission, which is crucial for applications that require high light levels.

The window is designed in the shape of a thin lens, which is often used in optical systems to reduce weight and thickness while maintaining optical performance. This feature makes the 11-739 an ideal choice for applications where space and weight are critical factors.
