The optical power meter OPM200 is designed for precise, high speed measurement of optical power in the μW to mW range. The output is a voltage linearly proportional to the input power. The gain of the OPM200 is fixed.
- Interfaces: DB9 (analogue outputs)
- Rise time: 70ns (5MHz)
- Noise equivalent power: 1 µW (RMS)
- Gain control: none
The OPM200 amplifier employs high quality photodiodes and precision transimpedance input stages to provide for low offset and high linearity throughout the full dynamic range.
FIELDS OF APPLICATION
These optical power monitors are particularly useful for the measurement of rapidly changing optical signals. These units have a particularly high bandwidth of 10MHz allowing monitoring of high frequency noise components of many light sources. The output is a voltage linearly proportional to input power. The fast response time at high signal-noise-ratio makes the OPM200 series particularly useful in systems control feedback loops.
The OPM200 series is insensitive to electromagnetic interference by design, an important factor when working in “dirty” industrial environments. These units are provided in OEM-style enclosures. The case wings provide for mounting on standard 25mm and 1″ optical table tops and for OEM applications.
