SLB-50B-80P 50.0 mm Dia. x 81.8 mm FL; Double-Convex Lens Uncoated
The SLB-50B-80P is a double-convex lens with a diameter of 50.0 mm and a focal length of 81.8 mm. This lens is sourced from OptoSigma, a renowned vendor known for their high-quality optical elements. The lens is made of n-bk7 schott, a popular material in the optical industry due to its excellent optical properties.
The lens features a base shape of a circle, with a thickness of 3 mm at the edge and 10.7 mm at the center. The effective focal length (EFL) is 81.8 mm, and the radii of curvature are 83.04 mm for the first surface and -83.04 mm for the second surface. The back focal length (BFL) is 78.2 mm.
Notably, this lens is uncoated, which means it does not have any anti-reflective or other coatings applied to its surfaces. This can be advantageous in certain applications where specific coatings are not required or desirable. However, it's important to note that uncoated lenses can have higher levels of surface reflection, which can affect the overall transmission and image quality.
