The 84-319 is a 15mm diameter, 45mm focal length plano-convex lens, specifically designed for use in the visible to near-infrared (VIS-NIR) spectrum, spanning 400-1000nm. This lens is sourced from the reputable optical vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.
The lens is made from fused silica, a material with the material ID 'fused sil mal-1965', ensuring high transmittance and durability. The front and back surfaces of the lens are coated with 'edm visnir0sp2002000', a coating optimized for the VIS-NIR range.
The lens's geometry is characterized by a 1.59mm edge thickness and a 3mm center thickness. The radius of curvature for the front surface is 20.63mm, and the back focal length is 42.94mm. The lens's shape is spherical, and it has no inner or outer radius, indicating a uniform curvature across the lens surface.
This lens is a type of spherical lens, specifically a plano-convex lens, which has one flat surface and one curved surface. The base shape is circular, making it suitable for a wide range of optical applications.
