SLSQ-50.8-100N 50.8 mm Dia. x -100.0 mm FL; Plano-Concave Lens Uncoated

The SLSQ-50.8-100N is a plano-concave lens with a diameter of 50.8 mm and a focal length of -100.0 mm, making it a negatively powered lens. This lens is sourced from OptoSigma, a renowned vendor in the optical industry, and is available for purchase on their website. The lens is uncoated, which means it does not have any additional layers to protect or enhance its optical properties.

The lens is made of fused silica, a high-quality material known for its excellent optical properties and durability. The geometry of the lens includes a thickness of 10.6 mm at the edge and 3 mm at the center, providing a substantial structural integrity. The inner and outer radii are both 0, indicating a flat surface on one side and a curved surface on the other.

The lens is designed to bend light rays to a single focal point, making it ideal for various applications such as beam expansion, collimation, and focusing. The SLSQ-50.8-100N operates at a wavelength of 546.1 nm, which is within the visible light spectrum. This wavelength is often used in optical systems for its high transmittance and ease of measurement.
