SLSQ-25-170N 25.0 mm Dia. x -170.0 mm FL; Plano-Concave Lens Uncoated
The SLSQ-25-170N is a Plano-Concave Lens with a diameter of 25.0 mm and a focal length of -170.0 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 is characterized by its base shape, which is circular, and its geometry specifications. The thickness at the edge of the lens is 3.0 mm, while the thickness at the center is 2.0 mm. The effective focal length (EFL) is -170.0 mm, and the radius of curvature (R1) is -78.2 mm. The back focal length (BFL) is -171.4 mm, and both the inner and outer radii are 0 mm.
The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. This may be suitable for applications where the lens will be used in a controlled environment or where specific coatings are not required.
The lens is in stock and available for immediate purchase. For more information, please refer to the vendor's website, which is provided in the item data.
