Molded chalcogenide aspheric lenses are crafted from advanced chalcogenide glass, known for exceptional infrared transmission across a wide spectral range. These lenses are precision-molded to create complex aspheric shapes that enhance optical performance by reducing aberrations in IR imaging systems, ideal for high-resolution thermal imaging and sophisticated surveillance technologies. Rely on CNGEIR, top aspheric lens manufacturers, for durable and precise lenses.
