65-269 2.5mm Dia. x 2.5mm FL; MgF2 Coated; Plano-Convex Lens MgF2 400-700nm
This is a 65-269 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens has a diameter of 2.5mm and a focal length of 2.5mm, making it a versatile choice for various applications.
The lens is made from n-lasf9 schott, a material known for its excellent optical properties. It is coated with edm mgf2 std curve on both the front and back surfaces, enhancing its performance in the 400-700nm wavelength range.
The geometry of the lens is carefully designed, with a thickness of 0.39mm at the edge and 0.8mm at the center. The 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 2.5mm, and the back focal length (BFL) is 2.05mm.
This lens is a Spherical type, which means it has a spherical surface. The radius of curvature (R1) is 2.12mm.
The lens is in stock and available for immediate purchase from the Edmund Optics website, as indicated by the "weblink status". The detailed specifications and the vendor's reputation make this lens a reliable choice for your optical needs.
