Optoelectronics & Engineering Services Fast Optical Power Monitor HIGHLIGHTS • Maximum input power • Noise equivalent power (NEPRMS) • Small signal rise time (10-90%) • Wide selection of photodiodes • Fast signal analysis • Component testing • Quality control • OEM (eg: laser noise monitoring) MEASUREMENT PRINCIPLE 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. 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. 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 FRONT AND BACK PANELS The front panel contains the input and output BNC connectors. The upper row of BNC connectors is for the current inputs. The channel count begins at the left. If the current source is a photodiode then the cathode is to be connected to the centre pin of the BNC. If a current source other than a photodiode is to be used, then the current drain is to be connected to the centre pin. The lower row of BNC connectors is for the amplifier outputs. The output is 0-4.5V, linearly proportional to the current input. The channel count begins at the left. The back panel...

INSTRUCTIONS FOR MEASUREMENT The OPM200 optial power monitor comprises one to four independent measurement channels, depending on the model chosen. Each channel consists of a receptacled optical input and a BNC-output. These two user interfaces are arranged in logical groups (see „The Front and Back Panels“). To make a measurement, proceed as follows: 1. Turn the unit on. For the most accurate measurement, please allow for a 15 minute warm up before using. 2. Connect an optical source to the desired channel via the corresponding receptacle. Ensure that the lug of the fibre connector is...

DAMAGE The unit may be damaged by exceeding the maximum average input power. Please read „Absolute Maximum Ratings“ for these maximum values before working with the instrument. Use only the power supply and power supply cable provided with the unit. TROUBLESHOOTING In the event that a measurement is not successful, the following possibilities should be analysed: Symptom Possible Errors Ensure the power cord is connected at both ends and switch the system on. Increase input power Input or output connection not correct Output at full scale, independant of input current • Input power too high...
