SLB-30B-80P 30.0 mm Dia. x 80.8 mm FL; Double-Convex Lens Uncoated

The SLB-30B-80P is a high-quality double-convex lens, sourced from the reputable optical component manufacturer, OptoSigma. This lens, with a base shape of a circle, is designed for use in a wide range of optical systems, thanks to its versatile specifications.

The lens has a diameter of 30.0 mm, providing a substantial surface area for light transmission. The thickness at the edge of the lens is 2.0 mm, while the center thickness is 4.7 mm, ensuring robustness and structural integrity. The effective focal length (EFL) of this lens is 80.8 mm, making it suitable for applications that require moderate magnification.

The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and chemical durability. The radii of curvature for the first and second surfaces are 83.04 mm and -83.04 mm, respectively, indicating a symmetrical, double-convex design. The back focal length (BFL) is 79.2 mm, which is crucial for determining the position of the lens in an optical system.

The SLB-30B-80P is uncoated, meaning it does not have any anti-reflective or other surface treatments. This may be suitable for applications where such coatings are not required or desirable. However, users should be aware that uncoated lenses can suffer from increased reflection, which may affect the performance of the optical system.
