SLB-05B-12P 5.0 mm Dia. x 12.3 mm FL; Double-Convex Lens Uncoated
The SLB-05B-12P is a 5.0 mm diameter double-convex lens with a focal length of 12.3 mm, sourced from OptoSigma. This lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion, making it ideal for a wide range of optical applications.
The lens features a base shape of a circle, with a thickness of 1.2 mm at the edge and 1.7 mm at the center. The effective focal length (EFL) is 12.3 mm, while the back focal length (BFL) is 11.7 mm. The radii of curvature are 12.46 mm for the first surface and -12.46 mm for the second surface, indicating a convex-convex or biconvex geometry.
Notably, this lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This may result in higher reflective losses, but it also means the lens can be used in a wider spectral range without concerns about coating performance.
