33-356 12.0mm Dia. x 36.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
This is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified as the 33-356, is designed with a 12.0mm diameter and a focal length of 36.0mm, making it suitable for a wide range of optical applications.
The lens is fabricated from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The base shape of the lens is circular, and it features a spherical geometry, which is a common choice for many optical systems due to its ease of manufacturing and high-quality image formation.
The lens's geometry includes a 2.01mm thickness at the edge and a 3mm thickness at the center. The effective focal length (EFL) is 36mm, and the radius of curvature (R1) is 18.61mm. The back focal length (BFL) is 34.02mm, and both the inner and outer radii are 0mm.
The lens is coated with Edmund Optics' NIR I Standard Curve coating on both the front and back surfaces. This coating is specifically designed for the near-infrared region, covering the wavelength spectrum of 600-1050nm. This coating enhances the lens's performance in the NIR region, providing improved transmission and reduced reflection.
