The 11-692 is a 12.7mm diameter, 50mm focal length Plano-Convex (PCX) lens designed for use in the infrared spectrum. This lens, sourced from Edmund Optics, is uncoated and features a thin design, making it an ideal choice for applications where space is at a premium.
The lens's geometry includes a 0.61mm edge thickness and a 1.5mm center thickness, with a 49.03mm back focal length (BFL) and a 22.95mm radius of curvature (R1). The lens's effective focal length (EFL) is 50mm, and it has no inner or outer radius, indicating a uniform curvature.
The lens is made from UVFS Mal-1965, a material specifically designed for use in the ultraviolet, visible, and shortwave infrared spectra. The wavelength of 587.6nm indicates that this lens is optimized for use in the visible spectrum, although its uncoated design may limit its performance in high-intensity applications.
