SLSQ-10-25N 10.0 mm Dia. x -25.0 mm FL; Plano-Concave Lens Uncoated

The SLSQ-10-25N is a Plano-Concave Lens, part of the Spherical Lens category, sourced from the reputable vendor OptoSigma. This lens is characterized by its fused silica material, which is known for its excellent optical properties, making it suitable for a wide range of applications.

The lens has a diameter of 10.0 mm and a thickness at the edge of 3.1 mm, ensuring durability and robustness. The center thickness is 2.0 mm, providing a balanced optical path length. The effective focal length (EFL) of this lens is -25.0 mm, indicating its concave nature. This negative focal length makes it ideal for use in applications where light needs to be diverged or where a virtual image is desired.

The radius of curvature (R1) is -11.5 mm, which is the curvature of the concave surface. The back focal length (BFL) is -26.4 mm, which is the distance from the rear surface of the lens to the focal point. The lens has no inner or outer radius, indicating it is a simple plano-concave design.

The lens is designed to operate at a wavelength of 546.1 nm, which is within the visible light spectrum. It is made of spherical geometry, a common and versatile shape in optical systems. The lens does not have any coating, which means it is uncoated. This may result in reduced transmission and increased susceptibility to environmental factors, but it also means that the lens is cost-effective and easy to clean.
