SLSQ-07B-12P 7.0 mm Dia. x 12.5 mm FL; Double-Convex Lens Uncoated

The SLSQ-07B-12P is a 7.0 mm diameter fused silica biconvex lens, uncoated, with a focal length of 12.5 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is designed with a base shape of a circle, featuring a convex-convex geometry, making it suitable for a wide range of optical applications.

The lens has a center thickness of 3 mm and an edge thickness of 1.9 mm, providing a balance between weight and optical performance. The effective focal length (EFL) is 12.5 mm, which is the distance from the lens's secondary principal plane to the focal point. The first and second radii of curvature (R1 and R2) are 11.04 mm and -11.04 mm respectively, indicating a symmetrically curved lens surface that contributes to its focusing power.

The back focal length (BFL) of this lens is 11.5 mm, which is the distance from the lens's rear surface to its secondary principal plane. The lens does not have any inner or outer radius, suggesting a uniform curvature across its surface.

The lens is made of fused silica, a high-quality material known for its excellent optical properties, including low autofluorescence, high transparency, and high resistance to thermal shock. The material ID for this lens is 'fused sil mal-1965', which can be used for further material specifications.

The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, uncoated lenses can be advantageous in certain applications where minimal reflection or dispersion is required.
