SLSQ-25-200N 25.0 mm Dia. x -200.0 mm FL; Plano-Concave Lens Uncoated

The SLSQ-25-200N is a Plano-Concave Spherical Lens, uncoated, with a diameter of 25.0 mm and a focal length of -200.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of fused silica, a material known for its excellent optical properties, including high transparency and resistance to thermal shock.

The lens geometry includes a thickness edge of 2.9 mm and a thickness center of 2 mm. The inner radius is 0 mm, and the outer radius is also 0 mm. The lens has a base shape of circular and a shape of spherical. The wavelength for this lens is 546.1 nm.

The SLSQ-25-200N is a Plano-Concave lens, meaning one side is flat (plano) and the other side is curved inward (concave). This type of lens is often used to diverge or spread out light, making it ideal for various applications such as beam expansion, collimation, and imaging.

The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. While this may result in a lower transmission rate and increased susceptibility to environmental factors, it also means the lens is less prone to internal reflections, which can be beneficial in certain applications.
