SLSQ-25B-30P 25.0 mm Dia. x 31.4 mm FL; Double-Convex Lens Uncoated

The SLSQ-25B-30P is a high-quality double-convex lens offered by OptoSigma, a leading vendor in the optical industry. This lens, with a diameter of 25.0 mm, is designed for use in a variety of optical systems, offering a focal length of 31.4 mm.

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 spherical geometry with a center thickness of 8.0 mm and an edge thickness of 2.0 mm. The lens's effective focal length (EFL) is 31.4 mm, and its back focal length (BFL) is 28.6 mm.

The SLSQ-25B-30P is uncoated, meaning it does not have any anti-reflective coatings. This can be beneficial in certain applications where the introduction of a coating might alter the optical properties of the lens. However, it's important to note that uncoated lenses can suffer from higher levels of reflection, which may impact the overall performance of the optical system.

The lens is designed to work with a wavelength of 546.1 nm, making it suitable for use in a wide range of applications. Its double-convex design, combined with its high-quality material and precise geometry, makes the SLSQ-25B-30P a reliable and versatile choice for many optical systems.
