The SLSQ-50-300N is a Plano-Concave Lens with a 50.0 mm diameter and a focal length of -300.0 mm, sourced from OptoSigma. This lens is made of fused silica, a material known for its excellent thermal stability and resistance to chemical etching.
The lens's geometry includes a thickness edge of 5.3 mm and a thickness center of 3 mm. The radius of curvature (R1) is -138 mm, and the back focal length (BFL) is -302.1 mm. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties.
This lens is suitable for applications that require a concave lens with a long focal length. Its high-quality fused silica material makes it suitable for use in harsh environments. However, its uncoated nature means it may not perform optimally in high-intensity light applications.
