SLSQ-25.4-150N 25.4 mm Dia. x -150.0 mm FL; Plano-Concave Lens Uncoated

OptoSigma's SLSQ-25.4-150N is a plano-concave lens made of fused silica, a material known for its excellent optical properties and high damage threshold. This lens has a diameter of 25.4 mm and a focal length of -150 mm, making it suitable for applications that require a large aperture and negative focal length.

The lens's geometry is characterized by its edge thickness of 3.2 mm and center thickness of 2 mm. The radius of curvature (R1) is -69 mm, and the back focal length (BFL) is -151.4 mm. The lens is uncoated, which means it does not have any anti-reflective or other coatings. This can be advantageous in certain applications where the introduction of a coating might alter the lens's optical properties.

The lens is designed to operate at a wavelength of 546.1 nm, which is in the green part of the visible spectrum. It is spherical in shape, a common geometry for lenses due to its ease of manufacturing and good optical performance.
