67-541 20.0mm Dia. x 150.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 67-541 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 20.0mm and a focal length of 150.0mm, making it suitable for a wide range of applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The lens features a front and back coating of edm nir-ii std curve, which enhances its performance in the near-infrared spectrum, specifically between 750nm and 1550nm. This coating is designed to reduce reflection and increase transmission, making the lens ideal for use in applications such as biomedical imaging, spectroscopy, and optical communication.
The geometry of the lens includes a thickness edge of 1.59mm and a thickness center of 3mm. The lens has an effective focal length (EFL) of 70mm and a radius of curvature (R1) of 36.18mm. The back focal length (BFL) is 68.03mm, and both the inner and outer radii are 0mm.
