45-480-INK 12.0mm Dia. x 12.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
This product is a plano-convex lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified as 45-480-INK, is designed for use within the visible to near-infrared spectrum, specifically catering to the wavelength of 587.6nm.
The lens boasts a circular base shape with a diameter of 12.0mm, and a thickness that varies from 1.84mm at the edge to 4.0mm at the center. The effective focal length (EFL) of the lens is 12.0mm, and it has a front radius (R1) of 9.42mm. The back focal length (BFL) is 9.76mm, and both the inner and outer radii are 0mm, indicating a plano surface on the opposite side of the convex surface.
The lens is constructed from n-SF11 Schott, a high-index glass with excellent optical properties. It is coated with a VIS-NIR coating, specifically the edm visnir0sp2002000 coating, on both the front and back surfaces. This coating enhances the lens's performance within the visible to near-infrared spectrum, providing improved transmission and reduced reflection.
