The 38-519-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 15.0mm, is designed for use in the visible to near-infrared (VIS-NIR) spectrum, specifically catering to the wavelength of 587.6nm.
The lens features a front and back coating of edm visnir0sp2002000, which is ideal for applications within the VIS-NIR range, 400-1000nm. The edge thickness of the lens is 1.4mm, while the center thickness is 3.8mm, providing a base shape that is circular.
The effective focal length (EFL) of the lens is 25mm, and the front radius (R1) is 12.92mm. The back focal length (BFL) is 22.5mm, and the lens does not have an inner or outer radius.
This lens is made of n-bk7 schott, a material known for its excellent optical properties. The lens is in stock, as indicated by its weblink status, making it readily available for your optical needs.
