The 38-279 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 10.0mm diameter and a 12.5mm focal length, making it suitable for a wide range of optical applications. The lens is made from n-sf11 Schott, a high-index glass with excellent optical properties.
The lens features a standard VIS 0° coating on both the front and back surfaces. This coating is designed to enhance the lens's performance in the visible light spectrum, specifically between 425-675nm. The coating helps to reduce surface reflections, improving the overall transmission of light through the lens.
The geometry of the lens is also noteworthy. The edge thickness measures 1.33mm, while the center thickness is 2.7mm. The lens's effective focal length (EFL) is 12.5mm, and the radius of curvature (R1) is 9.81mm. The back focal length (BFL) is 10.99mm, and both the inner and outer radii are 0mm.
