SLSQ-30-220N 30.0 mm Dia. x -220.0 mm FL; Plano-Concave Lens Uncoated

The SLSQ-30-220N is a Plano-Concave Lens with a diameter of 30.0 mm and a focal length of -220.0 mm, sourced from OptoSigma. This lens is made of fused silica, a material known for its excellent optical properties, durability, and resistance to thermal shock.

The lens geometry includes a thickness edge of 3.1 mm and a thickness center of 2 mm, providing a balanced structure for various applications. The inner and outer radii are both 0 mm, indicating a flat surface on one side and a concave surface on the other. The radius of curvature (R1) is -101.2 mm, and the back focal length (BFL) is -221.4 mm, further detailing the lens's curvature and optical properties.

This lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors. However, uncoated lenses often provide better light transmission for specific wavelengths, in this case, 546.1 nm.

The lens is available for purchase through the OptoSigma website, and the link provided indicates that it is currently in stock. This lens is a Spherical Lens of the Sub Type Plano-Concave and has a Circular base shape. It is a versatile component suitable for various optical systems and applications.
