SBC028 25.4 mm Dia. x -100 mm FL; Uncoated; Double-Concave Lens
The SBC028 is a spherical lens with a base shape of a circle, designed and manufactured by MKS/Newport. This lens is a part of their uncoated UVFS bi-concave lenses category, specifically designed for use in optical systems that require a double-concave lens.
The lens has a diameter of 25.4 mm and a thickness at the edge of 3.92 mm. The center thickness is 2.5 mm, providing a robust structure while maintaining a sleek profile. The effective focal length (EFL) of this lens is -100 mm, making it suitable for applications that require a negative focal length.
The first radius of curvature (R1) is -92.192 mm, and the second radius of curvature (R2) is 92.192 mm. These radii, combined with the EFL, contribute to the lens's double-concave shape. The back focal length (BFL) of this lens is -100.85 mm.
The lens is made of UVFS material with the material ID [UVFS mal- 1965]. It is designed to work optimally with a wavelength of 589 nm. The lens does not have any coating, which is indicated by the empty 'coating' parameter in the item data.
