49-177 3.0mm Dia. x 7.5mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 49-177 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. It boasts a 3.0mm diameter and a focal length of 7.5mm, making it a compact yet powerful optical component. The lens is made from the high-quality material n-BK7 Schott, ensuring durability and reliability.
The lens features a front and back coating of edm visnir0sp2002000, a VIS-NIR coating suitable for the wavelength of 587.6nm. This coating enhances the lens's performance in the visible to near-infrared spectrum, spanning from 400 to 1000nm. The coating also provides improved scratch resistance and reduced light loss due to reflection, thereby increasing the overall efficiency of the lens.
The geometry of the lens includes a thickness edge of 1.2mm and a thickness center of 1.5mm. The lens's inner and outer radii are both zero, indicating a uniform curvature. The lens's effective focal length (EFL) is 7.5mm, and its back focal length (BFL) is 6.51mm. The radius of curvature (R1) is 3.88mm.
