This is the PLCX-50.8-103.0-C, a Plano-Convex Laser Grade Spherical Lens with a 50.8 mm diameter, sourced from CVI Laser Optics. The lens is made of N-BK7 Schott glass, a popular material for its excellent optical properties and versatility.
The lens has a focal length (EFL) of 200mm, making it suitable for applications that require a longer focal length. The plano-convex design, where one side is flat and the other is curved, allows for efficient light gathering and focusing.
The lens has an outer radius of 0, indicating that it is a plano lens on one side, and an inner radius of 103mm, which is the radius of curvature of the curved side. The thickness at the edge is 3.2mm, and at the center, it is 6.4mm, providing structural integrity and resistance to deformation.
The lens is designed to work at a wavelength of 546.1nm, which is in the visible light spectrum. It does not come with any coating, which means it is uncoated. However, it can be customized with various coatings to enhance its performance or protect it from environmental factors.
