SLSQ-25B-35P 25.0 mm Dia. x 36.3 mm FL; Double-Convex Lens Uncoated

The SLSQ-25B-35P is a high-quality double-convex lens offered by OptoSigma, a renowned vendor in the optical industry. This lens, with a diameter of 25.0 mm, is designed for use in various optical systems that require a convex-convex lens shape.

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, ensuring uniform light transmission and minimal distortion.

The geometry of the lens is meticulously designed, with an edge thickness of 2 mm and a center thickness of 7.1 mm. The effective focal length (EFL) is 36.3 mm, making it suitable for applications that require a longer focal length. The first radius of curvature (R1) is 32.2 mm, while the second radius (R2) is -32.2 mm, indicating the double-convex nature of the lens. The back focal length (BFL) is 33.7 mm.

The lens is uncoated, which means it does not have any anti-reflective coatings. This may result in some light loss due to reflection, but it also means the lens is less prone to damage and contamination.

The SLSQ-25B-35P is designed to work with a wavelength of 546.1 nm, making it suitable for applications that use this specific wavelength, such as certain types of laser systems.
