32-938 15mm Dia. x 50mm FL Uncoated; Double-Convex Lens
The 32-938 is a 15mm diameter, 50mm focal length uncoated double-convex lens, available from Edmund Optics. This lens is a spherical lens with a convex-convex base shape and a circular geometry, making it suitable for a wide range of optical applications.
The lens has a diameter of 15mm, with a thickness of 1.9mm at the edge and 3mm at the center. The effective focal length (EFL) is 50mm, and the radii of curvature are 51.16mm for the first surface and -51.16mm for the second surface. The back focal length (BFL) is 49mm. The lens does not have any inner or outer radius, indicating a uniform thickness across the lens.
The lens is made of n-BK7 Schott, a popular optical glass known for its excellent optical properties. It is designed to work at a wavelength of 587.6nm. The lens does not have any coating, which means it is in its raw state. This could lead to reflections and scattering of light, but it also means that the lens is more cost-effective and suitable for applications where such effects are not critical.
