This is a ZnSe-px-76.2-200 Plano-Convex (PCX) lens, a product of Alkor Technologies. The lens has a diameter of 76.2 mm and an effective focal length (EFL) of 200 mm, making it suitable for a wide range of optical applications. The lens is made of ZnSe material, specifically the ZnSe marple-1964 variant, which is known for its excellent optical properties.
The lens geometry is characterized by its base shape, which is circular, and its thickness. The edge thickness is 3 mm, while the center thickness is 5.6 mm. The lens's inner and outer radii are both 0, indicating a plano-convex design. This design is often used in optical systems where a high level of convergence is required.
The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, its natural properties make it suitable for use in the infrared region, specifically at a wavelength of 10600 nm.
The lens is currently in stock and more information about it can be found on the Alkor Technologies website.
