Introduction
As the protective interface between high-intensity airfield lighting systems and harsh operating environments, our borosilicate glass lenses combine aerospace-grade material science with optical precision. The mould-pressed manufacturing process ensures consistent wall thickness for accurate light beam control, while the tempered borosilicate construction resists thermal shock from -40°C to 550°C. These covers meet the most demanding requirements for CAT II/III precision approach systems and high-traffic taxiways.
