65-283 2.0mm Dia. x 4.0mm FL; VIS 0deg Coated; Plano-Convex Lens VIS 0° 425-675nm
This is a 65-283 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens boasts a 2.0mm diameter and a 4.0mm focal length, making it suitable for a wide range of optical applications.
The lens is made from n-lasf9 Schott, a material known for its excellent optical properties. It is designed to work optimally with visible light, specifically within the 425-675nm wavelength range.
The lens features a standard VIS 0° coating on both the front and back surfaces. This coating enhances the lens's performance by reducing surface reflections and improving transmission, thereby increasing the overall efficiency of the optical system.
The geometry of the lens is meticulously crafted, with a 0.65mm edge thickness and a center thickness of 0.8mm. The lens's inner and outer radii are 0, indicating a flat surface on one side and a curved surface on the other. The effective focal length (EFL) is 4mm, and the back focal length (BFL) is 3.57mm.
