This is the PLCX-50.8-309.1-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, a popular material in the optical industry due to its excellent optical properties and versatility.
The lens has a focal length (EFL) of 600mm, making it suitable for applications that require long-range focusing. The plano-convex design, where one side is flat and the other is curved, allows for efficient light collection and focusing.
The lens has a thickness of 5.4mm at the edge and 6.4mm at the center. The curvature of the lens is defined by a radius (R1) of 309.1mm. The inner and outer radii are 0mm, indicating that the lens is a simple plano-convex design.
The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While this may limit its use in certain applications, it can be beneficial in others where the natural properties of the glass are desired.
