The 67-181-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 wavelengths of 587.6nm. The lens's geometry includes a thickness edge of 1.78mm and a thickness center of 2.0mm, with an effective focal length (EFL) of 90.0mm.
The lens's front and back surfaces are coated with "edm visnir0sp2002000", a coating specifically designed for VIS-NIR applications. This lens is circular in base shape and has an inner radius and outer radius of 0mm each, indicating a uniform curvature.
The lens material is n-BK7 Schott, a common optical glass known for its excellent transparency in the visible spectrum and good transparency in the near-infrared spectrum. The lens's geometry, coating, and material make it suitable for a wide range of applications in the VIS-NIR spectrum, such as imaging, spectroscopy, and beam shaping.
