Chalcogenide glass is a core amorphous infrared optical material with low dispersion and extreme environmental stability. Widely used in military night vision, infrared guidance, industrial gas detection and autonomous driving, featuring mass producibility and ongoing localization & miniaturization upgrades.

Why are there so many grades of optical glass? Discover core parameters (refractive index, Abbe number), glass families, key differences between N-BK7/N-SF11/LASF9, and practical tips for optical design, engineering, and material selection.

Learn how to read and interpret MTF curves professionally. Understand diffraction limit, lens aberrations including spherical aberration, coma and astigmatism, and master MTF evaluation for industrial lens selection & acceptance.
