65-287 2.5mm Dia. x 4.0mm FL; VIS 0deg Coated; Plano-Convex Lens VIS 0° 425-675nm
This is a 65-287 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens has a 2.5mm diameter and a 4.0mm focal length, making it suitable for a wide range of 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 curve coating on both the front and back surfaces. This coating, denoted as 'edm vis-0 std curve', is designed to enhance the lens's performance in the visible light spectrum.
The geometry of the lens is also noteworthy. It has an edge thickness of 0.56mm and a center thickness 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.
