SLSQ-25-50N 25.0 mm Dia. x -50.0 mm FL; Plano-Concave Lens Uncoated

The SLSQ-25-50N is a Plano-Concave Lens, a type of spherical lens, sourced from OptoSigma. This lens, with a diameter of 25.0 mm, is designed for use in systems operating at a wavelength of 546.1 nm. The lens is made of fused silica, a material known for its excellent optical properties, durability, and resistance to environmental factors.

The lens features a concave shape with a radius of curvature of -23 mm, resulting in a back focal length of -51.4 mm. The center thickness of the lens is 2 mm, while the edge thickness is 5.7 mm. Despite its compact size, the lens provides a substantial effect on the light path, making it suitable for various applications.

The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. This can be advantageous in certain applications where the user wants to minimize reflection or where the coating might interfere with the system's operation. However, it's important to note that uncoated lenses can have higher reflection losses and may require additional considerations for optimal performance.
