SLSQ-25-80N 25.0 mm Dia. x -80.0 mm FL; Plano-Concave Lens Uncoated
The SLSQ-25-80N is a Plano-Concave Lens, a type of spherical lens, sourced from OptoSigma. This lens is uncoated and features a fused silica material (fused sil mal-1965) which is known for its excellent transparency and resistance to thermal shock. The lens has a base shape of a circle and a subtype of Spherical Lens.
The lens has a diameter of 25.0 mm and a thickness at the edge of 4.2 mm. The center thickness is 2.0 mm, and the effective focal length (EFL) is -80.0 mm. The radius of curvature (R1) is -36.8 mm, and the back focal length (BFL) is -81.4 mm. The lens does not have an inner or outer radius.
The SLSQ-25-80N is designed to operate at a wavelength of 546.1 nm. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, uncoated lenses often have less light reflection and are more cost-effective.
