The 45-477-INK is a plano-convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 9.0mm, is designed for use in the visible to near-infrared (VIS-NIR) spectrum, specifically catering to the wavelength of 587.6nm. The lens's geometry includes a thickness of 1.0mm at the edge and 1.93mm at the center, with an effective focal length (EFL) of 22.0mm.
The lens's front and back surfaces are coated with "edm visnir0sp2002000", a coating specifically designed for VIS-NIR applications, enhancing its performance in this spectrum. The lens's inner and outer radii are 0, indicating a flat inner surface and a curved outer surface.
This lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens's shape, a plano-convex design, is often used in optical systems because it minimizes spherical aberration.
