67-504 12.0mm Dia. x 72.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. It is designed for use in the Near-Infrared (NIR) spectrum, specifically between 750nm and 1550nm, making it suitable for various applications in this range.
The lens has a diameter of 12.0mm and a focal length of 72.0mm. The edge thickness is 2.35mm, while the center thickness is 3.0mm. The effective focal length (EFL) is 54mm, and the front radius of curvature (R1) is 27.91mm. The back focal length (BFL) is 52.02mm, and both the inner and outer radii are 0mm.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. It is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces, which enhances its performance in the NIR spectrum.
