BF-px-50.8-200 50.8 mm Dia. BaF2 Plano-Convex Lens; EFL=200mm Uncoated
This is a Plano-Convex lens with a diameter of 50.8 mm, sourced from 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 200mm, meaning it will focus light at a distance of 200mm from the lens if the light rays are parallel to the lens axis.
The lens has a thickness of 2.5mm at the edge and 6.1mm at the center. The curvature of the lens is defined by a radius of 90.2mm on the convex side. The inner and outer radii are both 0, indicating that this lens does not have any concave surfaces.
The lens is uncoated, meaning it does not have any additional layers to protect it or modify its optical properties. This can make the lens more susceptible to damage and may affect its performance in certain applications, particularly those involving high-intensity light or extreme temperatures.
