Molded Infrared Aspheres

Molded Infrared Aspheres are crafted through a highly specialized process that utilizes ultra-high-precision molds. These molds are employed under the safeguard of inert gas atmospheres, with specific high temperatures and pressures applied to create infrared aspherical lenses. This method ensures that the lenses achieve exceptional contour accuracy and superior surface quality. One of the key benefits of Molded Infrared Aspheres is their cost-effectiveness, providing a low-cost solution without compromising on precision. Additionally, the process is well-suited for high-volume production, making these lenses an ideal choice for applications requiring both high precision and affordability in significant quantities.
