SLSQ-20-70P 20.0 mm Dia. x 70.0 mm FL; Plano-Convex Lens Uncoated

The SLSQ-20-70P is a Plano-Convex lens with a diameter of 20.0 mm and a focal length of 70.0 mm, sourced from the reputable vendor OptoSigma. This lens is made of fused silica, a material known for its excellent optical properties, including high transparency and resistance to thermal shock.

The lens geometry is characterized by a thickness of 2.0 mm at the edge and 3.6 mm at the center. The radius of curvature (R1) is 32.2 mm, and the back focal length (BFL) is 67.5 mm. The lens is uncoated, offering a cost-effective solution for applications where coating is not required or preferred.

This lens is suitable for a wide range of applications, including but not limited to imaging systems, beam shaping, and laser applications. The uncoated surface allows for custom coating options based on specific application requirements.

Please note that the lens is designed to operate at a wavelength of 546.1 nm. The provided web link leads to the vendor's page, where you can find more detailed specifications and availability status.
