SPC028 25.4 mm Dia. x -100 mm FL; Uncoated; Plano-Concave Lens

The SPC028 is a Plano-Concave Spherical Lens, sourced from the reputable vendor MKS/Newport. This lens boasts a diameter of 25.4 mm and a focal length of -100 mm, making it ideal for applications that require a negative focal length. The lens is uncoated, providing a bare, unaltered glass surface that can be beneficial in certain applications where coating might interfere with the optical path.

The lens's geometry is meticulously crafted, with a thickness at the edge of 3.95 mm and a center thickness of 2.5 mm. The inner and outer radii are 0, indicating a flat surface on one side and a concave surface on the other. The back focal length (BFL) is -101.71 mm, a value that is crucial in determining the lens's position in an optical system.

The lens is made of UVFS material, specifically identified as "UVFS mal- 1965". This material is well-suited for applications involving wavelengths of 589 nm. The lens's base shape is circular, ensuring uniformity in light collection and distribution.
