The 67-572-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 30.0mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically for wavelengths between 750 and 1550nm.
The lens features a front and back coating of edm nir-ii std curve, which is specifically designed for use in the NIR II spectrum. This coating enhances the lens' performance in this spectral range, providing superior image quality and light transmission.
The geometry of the lens includes a thickness at the edge of 2.82mm and a thickness at the center of 6.35mm. The effective focal length (EFL) of the lens is 50mm, and the radius of curvature (R1) is 33.63mm. The back focal length (BFL) is 46.17mm, and the lens does not have an inner or outer radius.
The lens is made from n-sf5 schott, a material known for its excellent optical properties in the NIR II spectrum. This material ensures high transmission rates and low absorption, making it ideal for use in applications such as biomedical imaging, night vision, and spectral analysis.
