The SLB-50B-70P is a high-quality double-convex lens offered by OptoSigma, a leading vendor in the optical industry. This lens, designed with a base shape of a circle, features a diameter of 50.0 mm and an effective focal length (EFL) of 72.0 mm, making it suitable for a wide range of optical applications.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. The double-convex geometry, characterized by radii of curvature R1 at 72.66 mm and R2 at -72.66 mm, ensures minimal spherical aberration and maintains high image quality.
The center thickness of the lens is 11.9 mm, while the edge thickness is 3 mm, providing sufficient mechanical strength and rigidity. The back focal length (BFL) of 68 mm allows for easy integration into optical systems.
This particular lens comes uncoated, providing users with the flexibility to apply custom coatings based on their specific application requirements. The lens is currently in stock and available for immediate shipping, as indicated by its valid web link status.
