32-626 25mm Dia. x 75mm FL Uncoated; Double-Convex Lens
The 32-626 is a 25mm diameter, 75mm focal length uncoated double-convex lens, available from Edmund Optics. This lens is a spherical lens, featuring a convex-convex base shape and a circular geometry. The lens's edge thickness measures 1.45mm, while the center thickness is 3.5mm, providing a robust structure.
The lens's effective focal length (EFL) is 75mm, and the first radius of curvature (R1) is 76.66mm, while the second radius of curvature (R2) is -76.66mm. The back focal length (BFL) is 73.84mm, and both the inner and outer radii are 0mm. This lens is made of N-BK7 Schott material, a popular choice for its high refractive index and low dispersion.
The lens is designed to operate at a wavelength of 587.6nm. It does not come with any coating, which means it is in its raw state, providing a clear, unaltered optical path. However, users should be aware that uncoated lenses may be more susceptible to surface reflections and scattering, which could affect image quality.
