SLSQ-50B-300P 50.0 mm Dia. x 300.9 mm FL; Double-Convex Lens Uncoated

The SLSQ-50B-300P is a high-quality double-convex lens offered by OptoSigma, a renowned vendor in the optical industry. This lens, with a diameter of 50.0 mm and a focal length of 300.9 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 spherical geometry with a center thickness of 5.3 mm and an edge thickness of 3 mm. The radii of curvature for the two surfaces are 276 mm and -276 mm, respectively, resulting in a back focal length of 299.1 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 user wants to control the reflection or transmission characteristics of the lens themselves. However, it's important to note that uncoated lenses can suffer from higher levels of reflection, which can reduce the overall efficiency of the optical system.

The SLSQ-50B-300P is designed to operate at a wavelength of 546.1 nm, making it suitable for use in a wide range of applications, from scientific research to industrial inspection and machine vision systems.
