This is a 10mm diameter, 10mm focal length (FL) double-convex lens, coated with NIR I for the spectral range of 600-1050nm. The lens is sourced from Edmund Optics, a reputable vendor in the optical industry.
The lens features a base shape of a circle and is made of n-SF5 Schott material, which is known for its high refractive index and low dispersion. This makes the lens suitable for applications that require high-quality imaging and minimal chromatic aberration.
The geometry of the lens includes a thickness of 1.45mm at the edge and 3.5mm at the center. The effective focal length (EFL) is 10mm, and the radii of curvature are 12.71mm for the first surface and -12.71mm for the second surface. The back focal length (BFL) is 8.89mm.
The lens is coated with EDM NIR-I standard curve on both the front and back surfaces. This coating enhances the lens's performance in the near-infrared region, improving transmission and reducing reflection. The coating is designed to maintain high performance across the specified spectral range.
