SLSQ-15B-40N 15.0 mm Dia. x -39.7 mm FL; Double-Concave Lens Uncoated
The SLSQ-15B-40N is a high-quality double-concave lens offered by OptoSigma, a leading vendor in the optical industry. This lens, with a diameter of 15.0 mm, is designed for use in a wide range of optical applications.
The lens features a base shape of a circle, with a thickness of 3.5 mm at the edge and 2.0 mm at the center. The effective focal length (EFL) of this lens is -39.7 mm, making it suitable for use in systems requiring a negative focal length. The first radius of curvature (R1) is -36.8 mm, while the second radius (R2) is 36.8 mm, indicating a symmetric, double-concave design.
The back focal length (BFL) of this lens is -40.3 mm. The lens is made from fused silica, a material known for its excellent optical properties, including high transparency and resistance to thermal shock.
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, particularly where cost-effectiveness is a priority.
The lens is designed to work with a wavelength of 546.1 nm. It is spherical in shape, a common choice for many optical applications due to its ease of manufacturing and versatility.
