33-409 40mm Dia. x 100mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm
This is a 40mm diameter, 100mm focal length double-convex lens, specifically designed for the visible to near-infrared spectrum (VIS-NIR), covering the wavelength range of 400-1000nm. The lens is sourced from the renowned optical vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.
The lens is made of the high-quality material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, including a low refractive index and low dispersion. This makes the lens suitable for a wide range of applications, particularly where high image quality and color correction are essential.
The lens features a front and back coating of edm visnir0sp2002000, a broadband anti-reflection coating specifically designed for the VIS-NIR spectrum. This coating significantly reduces surface reflections, enhancing the lens's light transmission capabilities and improving overall system performance.
The geometry of the lens includes a thickness of 4.04mm at the edge and 8mm at the center, with an effective focal length (EFL) of 100mm. The first and second radii of curvature (R1 and R2) are 101.98mm and -101.98mm, respectively, resulting in a back focal length (BFL) of 97.33mm. The lens has no inner or outer radius, indicating a uniform thickness across its diameter.
