SLSQ-07B-20P 7.0 mm Dia. x 20.4 mm FL; Double-Convex Lens Uncoated
The SLSQ-07B-20P is a high-quality double-convex lens offered by OptoSigma, a leading vendor in the optical industry. This lens, with a diameter of 7.0 mm, is designed for use in a wide range of optical applications.
The lens features a fused silica material (fused sil mal-1965) which is known for its excellent optical properties, including high transparency and resistance to thermal shock. The double-convex geometry, with radii of curvature R1 and R2 at 18.4 mm and -18.4 mm respectively, provides a focal length (FL) of 20.4 mm, making it suitable for applications requiring a long focal length.
The lens has a central thickness of 2.4 mm and an edge thickness of 1.7 mm, providing structural integrity and resistance to deformation. The uncoated surface ensures high light transmission but may require additional coatings for specific applications.
This lens is designed to work with a wavelength of 546.1 nm, making it suitable for use in a wide range of applications, from imaging to spectroscopy. The lens is currently in stock and available for immediate shipping, as indicated by its valid weblink status.
