32-996 25mm Dia. x -50mm FL; Uncoated; Double-Concave Lens
The 32-996 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 thickness at the edge of 5.4mm, while the thickness at the center is 2.5mm. The effective focal length (EFL) of this lens is -50mm, making it a double-concave lens.
The first radius of curvature (R1) is -52.1mm, and the second radius of curvature (R2) is 52.1mm. The back focal length (BFL) of this lens is -50.82mm. The 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.
The lens does not have any coating, which means it is in its raw state. This could lead to reflections and other optical issues, but it also means that the lens is suitable for applications where coating is not desired or necessary.
