A long-life metal halide illumination system, the Lumen 200S is a powerful 200-watt, cost-effective alternative to standard 100-watt mercury and halogen lamp houses traditionally used for fluorescence imaging. A built-in shutter can close in 30 ms, allowing very brief exposure periods thereby minimizing the risks of photo-bleaching damage even to sensitive samples. A wide variety of control options are available for the system, including RS232, USB, TTL and via the ProScan® III controller. Light is delivered via a 2m or 3m liquid light guide to eliminate heat transfer to the microscope, to minimizing thermal drift and aid image stability in long-term experiments.
The system’s spectral emission is similar to that of a traditional mercury bulb, covering most commonly used fluorophores and their corresponding filter sets. However, the manufacturer says light quality is superior, offering more even and consistent illumination across the spectrum and over time. Bulb life, at 2000 hours, is approximately ten times longer than that of a conventional mercury bulb, and bulb replacement is easy requiring no special realignment tools. Prior Scientific
