BF-px-50.8-500 50.8 mm Dia. BaF2 Plano-Convex Lens; EFL=500mm Uncoated
This is a Plano-Convex lens with a diameter of 50.8 mm, manufactured by Alkor Technologies. The lens is made of BaF2, a material with a refractive index that varies with wavelength, making it suitable for a wide range of applications. The lens has an effective focal length (EFL) of 500mm, making it a high-powered lens ideal for use in imaging systems that require a long focal length.
The lens geometry includes a thickness of 2.5mm at the edge and 3.9mm at the center. The curvature of the lens is defined by a radius of 224.9mm on the convex side, with the concave side having no curvature (R1=224.9, R2=0). This asymmetry in curvature contributes to the lens's high power and long focal length.
The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While this may result in a lower transmission rate and increased susceptibility to environmental factors, it also means that the lens is more cost-effective and easier to clean.
