38-273 6.0mm Dia. x 20mm FL; VIS 0° Coated; Plano-Convex Lens VIS 0° 425-675nm
The 38-273 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 6.0mm diameter and a 20mm focal length (FL), making it suitable for a wide range of optical applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The lens features a standard coating, specifically the EDM VIS-0 std curve, on both the front and back surfaces. This coating enhances the lens's performance in the visible light spectrum, particularly between 425 and 675nm. The coating helps to reduce surface reflections, improving the overall transmission of light through the lens.
The geometry of the lens includes a 1.01mm thickness at the edge and a 1.45mm thickness at the center. The lens's inner radius is 0mm, and the outer radius is also 0mm, indicating a uniform curvature. The lens's effective focal length (EFL) is 20mm, and the radius of curvature (R1) is 10.34mm. The back focal length (BFL) is 19.04mm.
