The 67-426 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 1.0mm and a focal length of 2.0mm, is designed for use in the near-infrared spectrum, specifically between 750nm and 1550nm.
The lens is made from n-lasf9 Schott, a material known for its excellent optical properties in the near-infrared range. It features a standard curve coating on both the front and back surfaces, specifically the 'edm nir-ii std curve' coating, which is designed to enhance its performance in the NIR II spectrum.
The geometry of the lens includes a thickness of 0.72mm at the edge and 0.8mm at the center. The lens's effective focal length (EFL) is 2.0mm, and its back focal length (BFL) is 1.57mm. The lens's inner and outer radii are both 0, indicating a plano-convex shape.
