38-299 12.7mm Dia. x 20.0mm FL; VIS 0deg Coated; Plano-Convex Lens VIS 0° 425-675nm
The 38-299 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 12.7mm diameter and a focal length of 20mm, 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, between 425 and 675nm. The coating reduces reflection and increases transmission, thereby improving the overall efficiency and quality of the optical system in which the lens is used.
The geometry of the lens is also noteworthy. The edge thickness is 1.62mm, while the center thickness is 3.8mm. The lens's inner radius is 0mm, and the outer radius is also 0mm, indicating a uniform curvature. The lens's front surface has a radius of curvature of 10.34mm, and the back focal length is 17.49mm.
