This is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens boasts a diameter of 25.4mm and a focal length of 38.1mm, making it suitable for a wide range of 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 NIR I coating on both the front and back surfaces. This coating, specifically designed for the 600-1050nm wavelength range, enhances the lens's performance in the near-infrared spectrum. It reduces reflection and increases transmission, thereby improving the overall efficiency and quality of the optical system in which it is used.
The lens has a spherical shape, with a radius of curvature of 19.69mm on the convex side. The center thickness of the lens is 7mm, while the edge thickness is 2.36mm. The back focal length is 33.48mm, and the effective focal length is the same as the focal length, at 38.1mm.
According to the vendor's information, this lens is currently in stock, making it readily available for immediate use. The detailed specifications and the vendor's reputation make this lens a reliable choice for various optical applications, particularly those requiring near-infrared transmission.
