BF-px-50.8-2000 50.8 mm Dia. BaF2 Plano-Convex Lens; EFL=2000mm Uncoated

Discover the BF-px-50.8-2000, a 50.8 mm diameter Plano-Convex lens made from BaF2, a unique material with exceptional properties. This lens, sourced from Alkor Technologies, offers an effective focal length (EFL) of 2000mm, making it ideal for applications requiring high magnification and narrow fields of view.

The lens geometry is meticulously designed, with a thickness of 2.5mm at the edge and 2.8mm at the center. The plano-convex shape, combined with an inner radius of 0 and an outer radius of 0, ensures a smooth transition of light, minimizing distortions and aberrations.

The material ID, "baf2 cgdm", indicates that this lens is made from Barium Fluoride (BaF2), a material known for its high transparency in the ultraviolet, visible, and infrared regions. This makes the lens suitable for a wide range of applications, including UV, visible, and IR imaging.

The wavelength of 5000 indicates the central wavelength of the lens, which is typically the wavelength at which the lens performs optimally. However, this lens, due to its broadband transparency, can perform well across a wide range of wavelengths.

Please note that this lens is uncoated. While uncoated lenses can provide excellent image quality, they may be more susceptible to surface reflections and scattering, which can reduce overall transmission and increase stray light.
