SLSQ-07-20P 7.0 mm Dia. x 20.0 mm FL; Plano-Convex Lens Uncoated

The SLSQ-07-20P is a 7.0 mm diameter, plano-convex lens with a focal length of 20.0 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 is characterized by its diameter, thickness, and radii of curvature. The diameter is 7.0 mm, and the edge thickness is 1.7 mm, while the center thickness is 2.4 mm. The radius of curvature of the convex surface is 9.2 mm, and the back focal length is 18.3 mm. The lens's effective focal length (EFL) is 20.0 mm, which is the distance from the lens's principal plane to the focal point.

This lens is designed for use at a wavelength of 546.1 nm, which is in the yellow-green part of the visible spectrum. It is a spherical lens, meaning it has a surface that is a portion of a sphere. The base shape is circular, which is the standard shape for most optical elements.

The SLSQ-07-20P is available from OptoSigma and is currently in stock. For more information, including pricing and availability, please refer to the vendor's website.
