The SLB-06B-08P is a 6.0 mm diameter, double-convex lens with a focal length of 8.4 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 mm at the edge and 2.1 mm at the center. The effective focal length (EFL) is 8.4 mm, while the back focal length (BFL) is 7.6 mm. The radii of curvature for the first and second surfaces are 8.3 mm and -8.3 mm, respectively.
Notably, this lens is uncoated, which means it does not have any anti-reflective or other coatings. While this may result in a higher level of reflection, it also means that the lens is more cost-effective and versatile, as it can be used in a variety of wavelengths without the need for specialized coatings.
