SLB-80B-200P 80.0 mm Dia. x 201.8 mm FL; Double-Convex Lens Uncoated

The SLB-80B-200P is a high-quality double-convex lens, sourced from the reputable optical vendor, OptoSigma. This lens, with a base shape of a circle, is designed for use in a wide range of optical applications, thanks to its precise geometry and material composition.

The lens has a diameter of 80.0 mm and a center thickness of 10.8 mm, ensuring a substantial surface area for light transmission. The edge thickness is 3.0 mm, providing structural rigidity and resistance to deformation. The effective focal length (EFL) of this lens is 201.8 mm, making it suitable for applications requiring moderate magnification and a relatively long focal length.

The lens is made of n-BK7 Schott glass, a popular material in the optical industry due to its excellent optical properties, including a high Abbe number and low dispersion. This makes the lens ideal for applications where color correction and minimal chromatic aberration are crucial.

The curvature of the lens is defined by its first and second radii of curvature, R1 and R2, which are 207.6 mm and -207.6 mm, respectively. These values indicate a symmetric, double-convex lens, which is beneficial for applications requiring a wide field of view and minimal spherical aberration.

Notably, this lens is uncoated, meaning it does not have any anti-reflective or other surface coatings. While this may result in higher reflective losses, it also means the lens can be used in a wider range of wavelengths, making it a versatile choice for many optical systems.
