45-245 50.0mm Dia. x 75.0mm FL; Plano-Convex Lens Uncoated
The 45-245 is a 50.0mm diameter, 75.0mm focal length Plano-Convex lens, uncoated and sourced from Edmund Optics. This lens is a Spherical Lens of the Sub Type Plano-Convex, with a Circular base shape. The lens has a diameter of 50.0mm, with a thickness at the edge of 1.86mm and a center thickness of 11.0mm. The Effective Focal Length (EFL) is 75.0mm, and the Radius of Curvature (R1) is 38.76mm. The Back Focal Length (BFL) is 67.75mm, and both the Inner and Outer Radius are 0.0mm.
The lens is made of N-BK7 Schott material, a popular choice for its high refractive index and low dispersion. It is designed to work with a wavelength of 587.6nm. The lens does not come with any coating, which may affect its performance in certain applications. However, its uncoated nature can make it more cost-effective and suitable for applications where coating is not necessary.
