The SLB-06B-10P is a 6.0 mm diameter double-convex lens with a focal length of 10.3 mm, sourced from OptoSigma. This lens is made of n-BK7 Schott glass, a popular material 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 1.0 mm at the edge and 1.9 mm at the center. The effective focal length (EFL) is 10.3 mm, while the back focal length (BFL) is 9.7 mm. The radii of curvature for the first and second surfaces are 10.38 mm and -10.38 mm, respectively.
Notably, this lens is uncoated, which means it does not have any anti-reflective or other coatings applied to its surfaces. This can result in higher reflective losses, but it also means the lens can be used in a wider range of wavelengths without the risk of coating damage.
The lens is designed for use at a wavelength of 546.1 nm, and it is spherical in shape. The lack of an inner or outer radius in the geometry suggests that this lens is a simple, uncut spherical lens.
