Are you looking for a simple to use, low cost fluorescent excitation system? Introducing the ARCLED 8 Channel LED engine. The ARCLED is a new approach on LED based excitation systems. Using no dichroic mirrors, the device can operate a wide range of LED channels. Positions inside the device may even include white LEDs! Our mirrorless design results in far greater utility, lower manufacturing costs, and greater flexibility as the needs of your research change over time. Want to test out a new fluorophore? With the ARCLED, simply order a new cube and install it. Want to use the ARCLED with an existing light source? We offer a custom modification that connects your existing 3mm or 5mm LLG equipped lamp, and relays it through the ARCLED lightpath.
