SLSQ-20-200P 20.0 mm Dia. x 200.0 mm FL; Plano-Convex Lens Uncoated

The SLSQ-20-200P is a Plano-Convex lens with a diameter of 20.0 mm and a focal length of 200.0 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 edge thickness of 2.0 mm and center thickness of 2.5 mm. The radius of curvature (R1) is 92.0 mm, and the back focal length (BFL) is 198.3 mm. The lens's clear aperture is the same as its diameter, and it does not have any inner or outer radii. The lens is designed to operate at a wavelength of 546.1 nm.

This lens is suitable for various applications that require a high-quality, spherical lens. 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 coated lenses are not necessary. The lens's high-quality fused silica material ensures excellent optical performance and durability, making it a reliable choice for various optical systems.
