A stepped reflector wall layout confines stray light near the diffuser while preserving uniform backlighting and lower heat loss.
A tuned antioxidant, epoxy, and UV absorber blend helps polycarbonate LED lenses keep color tone and resist moist heat and irradiation.
Stacked anti-reflection layers and nano-post meta-micro-lenses cut surface reflection while improving light condensation in compact image sensors.
A diffuser and waveguide reshape coherent light to improve beam uniformity, preserve optical efficiency, and reduce speckles.
