This is a ZnSe-px-12.7-50 Plano-Convex (PCX) lens, a product of Alkor Technologies. The lens, which is made of Zinc Selenide (ZnSe) material, has a diameter of 12.7 mm and an effective focal length (EFL) of 50.8 mm. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties.
The lens's geometry is characterized by its edge thickness of 2 mm and center thickness of 2.3 mm. The lens's base shape is circular, and it has a spherical shape with a radius of curvature (R1) of 71.46 mm for the convex surface. The lens does not have an inner radius (R2), and its outer radius is also not specified, indicating that it is a plano lens on the other side.
The lens is designed to operate at a wavelength of 10600 nm, making it suitable for infrared applications. The material ID for this lens is 'znse marple-1964', which can be used for referencing and cataloguing purposes.
