This is a Plano-Convex Lens, type 38-584, sourced from the renowned optical components vendor, Edmund Optics. The lens boasts a circular base shape with a 12.5mm diameter, making it suitable for a wide range of applications. The lens has a center thickness of 3.1mm and an edge thickness of 1.49mm, providing a balance between weight and optical performance.
The lens' effective focal length (EFL) is 25mm, which is a common choice for many optical systems due to its versatility. The radius of curvature (R1) is 12.92mm, and the back focal length (BFL) is 22.96mm, contributing to the lens' overall optical properties.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The lens is coated with YAG-BBAR, a type of coating that enhances its performance in the 500-1100nm wavelength range. This coating reduces reflection and increases transmission, making the lens ideal for use in laser systems and other applications where high transmission is required.
