65-299 2.0mm Dia. x 4.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 65-299 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 2.0mm diameter and a 4.0mm focal length, making it suitable for a variety of applications. The lens is made from n-lasf9 Schott, a material known for its high refractive index and low dispersion, which contributes to superior image quality.
The lens features a front and back coating of edm visnir0sp2002000, a VIS-NIR coating designed for use in the visible and near-infrared spectrum (400-1000nm). This coating enhances the lens's performance by reducing surface reflections and increasing transmission, thereby improving light gathering capabilities.
The geometry of the lens includes a thickness edge of 0.65mm and a thickness center of 0.8mm. The lens's effective focal length (EFL) is 4mm, and its radius of curvature (R1) is 3.4mm. The back focal length (BFL) is 3.57mm, and both the inner and outer radii are 0mm.
The lens's information is valid and in stock, according to the vendor's website. This makes the 65-299 an ideal choice for those seeking a high-quality, reliable, and readily available Plano-Convex lens for their optical systems.
