SLSQ-25B-35N 25.0 mm Dia. x -34.7 mm FL; Double-Concave Lens Uncoated

The SLSQ-25B-35N is a high-quality, double-concave lens offered by OptoSigma. This lens, with a diameter of 25.0 mm, is designed for use in a wide range of optical applications. The lens's base shape is circular, and it features a double-concave geometry, making it suitable for applications requiring light convergence or dispersion.

The lens has a center thickness of 2.0 mm and an edge thickness of 7.1 mm, providing excellent structural integrity. The effective focal length (EFL) of this lens is -34.7 mm, indicating its strong converging properties. The first radius of curvature (R1) is -32.2 mm, and the second radius (R2) is 32.2 mm, which are essential parameters for designing optical systems.

The lens is made of fused silica, a material known for its high transparency and excellent thermal stability. The material ID for this lens is "fused sil mal-1965", which can be used for further material specifications. The lens is designed to operate at a wavelength of 546.1 nm.

Notably, this lens is uncoated, which means it does not have any anti-reflective or other surface coatings. While this may result in higher reflective losses, it also means the lens can be used in a wider range of applications without worrying about coating compatibility issues.
