Glass Fresnel Lenses (Heat-Resistant Optics)
Glass Fresnel lenses are optical components manufactured with concentric micro-grooves precision-molded into one surface, functioning as a continuous series of individual refracting surfaces to concentrate and shape light beams.
Functions:
Provides short focal lengths, high luminous flux, and compact optical profiles while dramatically reducing lens mass and glass volume compared to conventional thick optical lenses. Engineered from high-purity, heat-resistant glass to withstand high thermal loads in continuous high-wattage illumination systems without thermal distortion.
Applications:
Stage spotlights
Theatrical fixtures
Architectural searchlights
High-bay industrial luminaires
Solar concentration collectors
Maritime lighthouse optics.
