SLSQ-30-150N 30.0 mm Dia. x -150.0 mm FL; Plano-Concave Lens Uncoated

The SLSQ-30-150N is a Plano-Concave Lens, a type of spherical lens, sourced from OptoSigma. This lens, with a diameter of 30.0 mm, is designed for use in systems where a negative focal length is required. The lens has a base shape of a circle and is uncoated, offering a high-quality, unaltered optical surface.

The lens's geometry is defined by its diameter, thickness, and focal length. The edge thickness of the lens is 3.7 mm, while the center thickness is 2 mm. The effective focal length (EFL) is -150.0 mm, indicating a concave lens. The first radius of curvature (R1) is -69.0 mm, and the back focal length (BFL) is -151.4 mm. The lens does not have an inner or outer radius, indicating a uniform curvature across the surface.

The lens is made from fused silica, a material with the material ID "fused sil mal-1965". This material is known for its excellent optical properties, making it suitable for a wide range of applications. The lens is designed to operate at a wavelength of 546.1 nm.

Please note that the lens is uncoated, meaning it does not have any anti-reflective or other surface coatings. This may affect its performance in certain applications, particularly those involving high-intensity light sources or specific wavelength ranges.
