LED Light Guides

LED light guides are efficient tools, perfect for directing the output of a distant light source to a target point. They are your go-to option for several reasons, perhaps the most compelling being that you need a powerful light source, but have to deal with the constrictions of a tight design envelope. Light-guide-coupled installations also have the edge if you need high radiation output from a freely movable light exit, are aiming for a lightweight design, or have to satisfy strict safety requirements in a controlled environment. In any case, the hallmarks of a good light guide are excellent transmission, high mechanical flexibility, robustness, and reliable performance over a long service life. Primelite’s LED Light Guides tick all these boxes.

LEDs are high-NA light emitters with a broad angular radiation pattern. Efficiency is paramount in setups that pair LEDs with light guides. These light guides have to transmit maximum radiation to the target point. This means the LED source’s NA has to match light guide’s NA. We offer single- and multi-pole liquid light guides perfectly matched to our LED light sources. In our exposure systems, they typically deliver two to three times as much power as conventional silica fiber light guides.
