This 38-275 optical lens, sourced from Edmund Optics, is a Plano-Convex Spherical Lens with a 6.0mm diameter and a focal length of 25mm. The lens is made from the high-quality material n-BK7 Schott, ensuring excellent optical performance. The lens's front and back surfaces are coated with the EDM VIS-0 standard curve coating, providing superior transmission in the visible spectrum, specifically between 425-675nm.
The lens's geometry includes an edge thickness of 1.1mm and a center thickness of 1.45mm. The inner radius is 0mm, and the outer radius is also 0mm. The lens's effective focal length (EFL) is 25mm, and the back focal length (BFL) is 24.04mm. The radius of curvature for the first surface (R1) is 12.92mm.
This lens is an excellent choice for applications that require a high-quality, visible light lens with a wide spectral range. Its Plano-Convex design and high-quality coating make it suitable for various optical systems, including imaging systems, beam shaping, and other applications where high transmission and excellent optical quality are required.
