The SLSQ-50.8-90N is a Plano-Concave Lens with a diameter of 50.8 mm and a focal length of -90.0 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 spherical shape. The thickness at the edge of the lens is 11.7 mm, while the thickness at the center is 3 mm. The inner and outer radii are both 0 mm, indicating a uniform curvature. The lens's effective focal length (EFL) is -90.0 mm, and the back focal length (BFL) is -92.1 mm.
The SLSQ-50.8-90N is uncoated, meaning it does not have any additional layers to enhance its optical properties. This lens is designed to operate at a wavelength of 546.1 nm. It's important to note that the lens is in stock and the web link provided is valid, making it readily available for your optical needs.
