Filters

Most electrical and electronic equipment generates and/or is affected by EMI. Sources are everywhere, including AC motors, fluorescent bulbs/ballasts, dimmers, microwave ovens, microprocessors, computers, and switch-mode power supplies. EMI power line filters are suitable for appliances, electronic equipment, power lines and other ...
Data Sheet
The Laser Line Tunable Filter (LLTF) is a non-dispersive tunable bandpass filter based on volume holographic gratings. It delivers the highest signal throughput in the industry, and is also unique in that it combines very high optical density (> OD6) and outstanding out-of-band rejection with wide tunability. A single filter can ...
