SBC031 25.4 mm Dia. x -75 mm FL; Uncoated; Double-Concave Lens
The SBC031 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 with a wavelength of 589 nm. The lens is constructed with a diameter of 25.4 mm, making it suitable for a wide range of optical applications.
The lens features a double-concave design, with the first radius of curvature (r1) measured at -69.241 mm and the second radius of curvature (r2) measured at 69.241 mm. This design results in a back focal length (bfl) of -75.85 mm and an effective focal length (efl) of -75 mm. The edge thickness of the lens is 4.4 mm, while the center thickness is 2.5 mm, providing a robust and durable structure.
The lens material is UVFS, identified as "UVFS mal- 1965" in the Material ID. The coating for this lens is unspecified, indicating that it is likely uncoated. This could make it ideal for applications where coated lenses may introduce unwanted reflections or other optical effects.
The weblink provided is valid and indicates that the lens is in stock, making it readily available for immediate use in your optical systems.
