SLSQ-30-4000P 30.0 mm Dia. x 4000.0 mm FL; Plano-Convex Lens Uncoated

OptoSigma's SLSQ-30-4000P is a Plano-Convex lens, a type of spherical lens, designed with a circular base shape. This lens is uncoated and made of fused silica, specifically identified as "fused sil mal-1965" in the material database. The lens has a diameter of 30.0 mm and a thickness at the edge of 2.0 mm, while the center thickness is slightly more at 2.1 mm.

The effective focal length (EFL) of this lens is 4000.0 mm, making it suitable for applications that require long focal lengths. The first radius of curvature (R1) is 1840.0 mm, and the back focal length (BFL) is 3998.6 mm. The lens does not have an inner or outer radius, indicating a uniform curvature.

This lens is designed to operate at a single wavelength of 546.1 nm. The shape of the lens is spherical, a common choice for its simplicity and versatility. The lack of coating on this lens means it will have a higher reflectivity compared to coated lenses, but it also means it is more cost-effective and less prone to damage from environmental factors.

The lens is currently in stock and available for purchase through the OptoSigma website, as indicated by the "weblink status" field in the item data.
