SLSQ-25B-40P 25.0 mm Dia. x 41.1 mm FL; Double-Convex Lens Uncoated
The SLSQ-25B-40P is a high-quality, double-convex lens offered by OptoSigma. This lens, with a diameter of 25.0 mm, is designed for use in a variety of optical applications. The lens features a focal length of 41.1 mm, making it suitable for systems that require a longer focal length.
The lens is made of 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 has a center thickness of 6.4 mm and an edge thickness of 2 mm. The lens's geometry also includes an inner radius of 0 and an outer radius of 0.
The SLSQ-25B-40P is uncoated, which means it does not have any anti-reflective coatings. This may be suitable for applications where such coatings are not necessary or desirable. However, users should be aware that uncoated lenses can suffer from reflective losses, which can reduce the overall efficiency of the optical system.
The lens is designed to work with a wavelength of 546.1 nm, which is within the visible light spectrum. It is a spherical lens, meaning it has a spherical surface, which is a common type of lens used in many optical systems.
