Keystone Electronics's 8689 redefines optical performance for optoelectronic systems requiring absolute precision. These advanced lenses incorporate chalcogenide glass formulations for exceptional IR transmission properties. The 8689 series maintains <0.2 wave RMS surface accuracy across all production units. With optional hydrophobic coatings, these lenses resist fogging and contamination in challenging environments. Primary applications include thermal imaging systems, missile guidance optics, and industrial process monitoring equipment. The 8689 has become essential in gas detection systems, food sorting machines, and astronomical observation instruments. Many defense contractors specify these lenses for surveillance systems, while medical manufacturers incorporate them into laser surgery apparatus for their reliable performance.
