SLSQ-20-80P 20.0 mm Dia. x 80.0 mm FL; Plano-Convex Lens Uncoated

The SLSQ-20-80P is a Plano-Convex lens with a diameter of 20.0 mm and a focal length of 80.0 mm, sourced from OptoSigma. This lens is made of fused silica, a material known for its excellent optical properties, durability, and resistance to thermal shock. The lens is uncoated, which means it does not have any additional layers to enhance its optical performance or protect it from environmental factors.

The lens's geometry includes a thickness of 2.0 mm at the edge and 3.4 mm at the center. The radius of curvature (R1) is 36.8 mm, and the back focal length (BFL) is 77.7 mm. The effective focal length (EFL) is 80.0 mm. The lens is spherical in shape, and it is designed to work with a wavelength of 546.1 nm.

This lens is suitable for various applications that require a high-quality optical component with a long focal length. Its uncoated surface may make it more susceptible to environmental factors, but it can also make it more cost-effective and suitable for applications where coating is not necessary or desirable.
