63-826 9mm Dia. x 36mm FL; VIS-NIR Coated; UV Double-Convex Lens VIS-NIR 400-1000nm
This is a 63-826 model lens, featuring a 9mm diameter and a 36mm focal length. It is a spherical lens with a convex-convex base shape, making it suitable for a wide range of optical applications. The lens is circular in shape, with a thickness of 1.38mm at the edge and 2mm at the center.
The lens has an effective focal length (EFL) of 36mm, and the first and second radii of curvature (R1 and R2) are 32.69mm and -32.69mm respectively. The back focal length (BFL) is 35.31mm. The inner and outer radii are both 0mm, indicating a uniform curvature throughout the lens.
The lens is made from fused silica material, specifically identified as fused sil mal-1965 in the item data. This material is known for its excellent optical properties, making it ideal for use in the visible to near-infrared (VIS-NIR) spectrum, specifically between 400 and 1000nm.
The lens is coated with a VIS-NIR coating, denoted as edm visnir0sp2002000, on both the front and back surfaces. This coating enhances the lens's performance in the VIS-NIR spectrum, reducing reflection and increasing transmission.
