67-427 1.5mm Dia. x 1.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 67-427 is a Plano-Convex lens, a type of spherical lens, with a diameter of 1.5mm and a focal length of 1.0mm. This lens is sourced from Edmund Optics, a renowned vendor in the optical industry. The lens is made from n-lasf9 Schott, a material known for its excellent optical properties.
The lens's geometry is meticulously designed, with a thickness of 0.35mm at the edge and 0.8mm at the center. The effective focal length (EFL) is 1mm, and the radius of curvature (R1) is 0.85mm. The back focal length (BFL) is 0.57mm, and both the inner and outer radii are 0mm.
The 67-427 is coated with the EDM NIR-II std curve on both the front and back surfaces. This coating enhances the lens's performance in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm. The lens is currently in stock and available for immediate purchase, as indicated by its valid weblink status.
