Ge-px-76.2-200 76.2 mm Dia. Germanium Plano-Convex Lens; EFL=200mm Uncoated
This is a 76.2 mm diameter Germanium Plano-Convex lens, offered by Alkor Technologies. The lens is uncoated and has an effective focal length (EFL) of 200mm, making it suitable for a variety of applications that require long focal lengths.
The lens geometry is characterized by a thickness of 3.1mm at the edge and 4.3mm at the center. The radius of curvature (R1) is 597.16, indicating a moderately curved lens surface. The lens is designed to operate at a wavelength of 10600nm, which is within the infrared spectrum.
The lens is made of Germanium burnett, a material known for its high refractive index and transparency in the infrared region. This makes the lens an excellent choice for applications such as thermal imaging, night vision, and other infrared-based technologies.
Please note that the lens is uncoated, which means it may not perform optimally in high-intensity light conditions or in applications where surface protection is a concern. However, uncoated lenses can offer superior optical clarity and are often more cost-effective.
