NightStar FAQs - Why was a lens chosen for the output window?

Placing a specially designed acrylic lens at the appropriate point effectively collects and images the light output from the LED. The lens also serves as a window, and due to its design it is able to withstand tremendous pressure, shock and hazardous chemical environments. Therefore, with a single component, optimum light output and durability are obtained.
