This ZnSe-px-25.4-200 is a Plano-Convex Spherical Lens, boasting a diameter of 25.4 mm and a focal length of 200 mm. The lens is sourced from Alkor Technologies, a reputable vendor in the optical industry. 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 edge thickness of 2 mm and center thickness of 2.3 mm. The lens's inner and outer radii are both 0, indicating a Plano-Convex shape. The lens is designed to operate at a wavelength of 10600 nm.
Notably, this lens is uncoated, which means it does not have any additional layers to enhance its optical properties. While this may limit its performance in certain applications, it can be advantageous in others where specific coatings may interfere with the desired optical effects.
