The SLSQ-50-80N is a Plano-Concave Lens, part of OptoSigma's extensive catalog of optical elements. This lens, with a diameter of 50.0 mm, is designed for use in a wide range of optical applications. The lens's concave shape, characterized by a radius of curvature of -36.8 mm, contributes to its negative focal length of -80.0 mm.
The lens is made of fused silica, a material known for its excellent optical properties, including high transparency across a wide spectrum, making it suitable for use in various wavelength ranges. The material's low coefficient of thermal expansion also ensures dimensional stability over a wide temperature range.
The lens's edge thickness is 12.8 mm, while the center thickness is 3 mm, providing structural integrity and minimizing optical distortions. The lens's design is spherical, a common and well-understood geometry in optical systems.
Notably, this lens is uncoated. While coatings can enhance the performance of optical elements by reducing surface reflections, increasing transmission, or providing environmental protection, an uncoated lens can be advantageous in certain applications where specific coating properties are not required.
