SLSQ-25.4-90P 25.4 mm Dia. x 90.0 mm FL; Plano-Convex Lens Uncoated

The SLSQ-25.4-90P is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 90.0 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 1.9 mm at the edge and 3.9 mm at the center. The effective focal length (EFL) is 90 mm, and the radius of curvature (R1) is 41.4 mm. The back focal length (BFL) is 87.3 mm, and the lens does not have any inner or outer radius, indicating it is a simple Plano-Convex lens.

This lens is suitable for applications that require a high level of optical precision and where environmental factors are not a significant concern. It can be used in a wide range of fields, including but not limited to, imaging, beam shaping, and laser applications.

Please note that the lens is uncoated, and additional coatings may be required depending on the specific application. Always refer to the vendor's specifications and consult with an optical expert when in doubt.
