The 32-992 is a spherical lens with a base shape of a circle, sourced from the reputable vendor, Edmund Optics. This lens falls under the category of a Spherical Lens (Concave-Concave) and is uncoated. The lens has a diameter of 25mm and a focal length of -25mm, making it a double-concave lens.
The lens's geometry is meticulously designed with an edge thickness of 6.05mm and a center thickness of 2.5mm. The effective focal length (EFL) is -25mm, and the first radius of curvature (R1) is -39.78mm, while the second radius of curvature (R2) is 39.78mm. The back focal length (BFL) is -25.69mm. The lens does not have any inner or outer radius.
The lens is made of n-sf11 Schott material, which is a high-index glass with excellent optical properties. It is designed to operate at a wavelength of 587.6nm. The lens does not have any coating, which means it is in its raw state, providing bare optics.
