SLSQ-15B-70P 15.0 mm Dia. x 70.5 mm FL; Double-Convex Lens Uncoated

The SLSQ-15B-70P is a high-quality double-convex lens offered by OptoSigma, a renowned vendor in the optical industry. This lens, with a diameter of 15.0 mm and a focal length of 70.5 mm, is designed for use in a variety of optical systems.

The lens is made of fused silica, a material known for its excellent optical properties, including high transparency and resistance to thermal shock. The base shape of the lens is circular, and it features a double-convex geometry, with radii of curvature of 64.4 mm for the first surface and -64.4 mm for the second surface. This geometry results in a back focal length of 69.5 mm.

The lens is uncoated, which means it does not have any anti-reflective or other coatings applied to its surfaces. This can be advantageous in certain applications where the natural properties of the lens material are desired. However, it's important to note that uncoated lenses can exhibit higher levels of reflection, which may need to be taken into account in the design of the optical system.

The lens has a thickness of 2.0 mm at the edge and 2.9 mm at the center. The material index is 1.965, and the wavelength of operation is 546.1 nm. This lens is currently in stock and available for immediate purchase.
