83-476 40 mm Dia. N-BK7 Precision Protective Flat Window; t=4 mm NIR I 600-1050nm
The 83-476 is a 40 mm diameter, 4 mm thick N-BK7 window, coated with EDM NIR-I standard curve on both the front and back surfaces. This window is sourced from Edmund Optics and is currently in stock, as indicated by its weblink status.
The window is designed as a flat window, featuring a base shape of a circle. The material of the window is N-BK7 Schott, a popular choice in the optical industry due to its excellent optical properties and high Abbe number. The window has a diameter of 40 mm and a thickness of 4 mm, making it suitable for a wide range of applications.
The window is coated with the EDM NIR-I standard curve on both the front and back surfaces. This coating is specifically designed for use in the near-infrared region, providing high transmission and low reflection in the 600-1050 nm wavelength range. This makes the window ideal for applications that require high-quality imaging or transmission in the near-infrared region.
The window is shaped as a thin lens, which is a type of lens where the thickness of the lens is much less than the diameter of the lens. This shape is often used in optical systems where a flat surface is required, such as in beam splitters or windows.
