SLSQ-07B-25P 7.0 mm Dia. x 25.4 mm FL; Double-Convex Lens Uncoated

The SLSQ-07B-25P is a high-quality double-convex lens offered by OptoSigma, a renowned vendor in the optical industry. This lens, with a diameter of 7.0 mm, is designed for use in a variety of applications that require precise optical performance.

The lens is made from fused silica, a material known for its excellent optical properties, including high transparency and resistance to thermal shock. The base shape of the lens is circular, and it features a double-convex geometry, meaning it has a convex shape on both sides. This design allows for a wide range of focal lengths and a high level of light concentration.

The SLSQ-07B-25P has a thickness of 1.7 mm at the edge and 2.2 mm at the center. The effective focal length (EFL) of the lens is 25.4 mm, which is the distance from the lens's principal point to the focal point. The first radius of curvature (R1) is 23 mm, and the second radius of curvature (R2) is -23 mm, indicating the lens's convex-convex shape. The back focal length (BFL) of the lens is 24.6 mm.

This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, it is still suitable for many applications where high light transmission and excellent image quality are required. The lens is designed to work with a wavelength of 546.1 nm.
