LEDiL's LISA2 series of lenses, measuring less than 10 mm in diameter and less than 7 mm tall, achieve over 90% light transmission efficiency through superior design and superior material.

The TIR lens is engineered to exacting tolerances and molded from high-quality acrylic (PMMA), which offers outstanding transmission efficiency and is virtually impervious to UV radiation. Each lens is mounted in a molded polycarbonate (PC) housing designed for alignment to a specific LED, providing precise location of the lens at the ideal focal point for each qualified brand or style of LED.
