The 67-180-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 features a front and back coating of edm visnir0sp2002000, which is ideal for applications within the VIS-NIR range, enhancing its performance and durability. The edge thickness of the lens is 1.73mm, while the center thickness is 2.0mm, providing a robust structure.
The effective focal length (EFL) of the lens is 72.0mm, and its radius of curvature (R1) is 37.21mm. The back focal length (BFL) is 70.68mm, and the lens has no inner or outer radius, indicating a uniform curvature.
This lens is made of n-bk7 schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence. The lens is inked, a process that enhances its traceability and identification.
