Optoelectronics & Engineering Services miniature Optical Power Monitor HIGHLIGHTS • Dimensions (free beam input) Tight space applications for: • Laser stabilisation • Dimensions φ12 x 12.5 mm (fibre receptecled) • Noise equivalent power (NEPRMS) • Rise / Fall time (10% - 90%) • Laser monitoring linear analogue MEASUREMENT PRINCIPLE The OPM100 series of optical power monitors employs photodiodes to measure optical power. A precision transimpedance input stage provides for high linearity throughout the full dynamic range of the system. Several options of photodiode material and optical input, including free beam input, make these units useful in a wide range of applications. Due to the very small package size, these units fit into the tightest spaces for your OEM application. The output of these optical power monitors is a voltage linearly proportional to power. The fast response time at high signal-noise-ratio makes the OPM100 series particularly useful in systems control feedback loops, such as in laser power stabilisation systems.

ABSOLUTE MAXIMUM RATINGS Average Optical Power Temperature Range Power Supply ORDERING INFORMATION Full order code: Options free beam For example, a unit with a silicon (Si) photodiode and FC-receptacle input would be ordered as: OPM100SF Note: The OPM100 series is designed for tight space OEM applications. The user must supply the unit with a clean DC power supply of nominally 5 V.

INSTRUCTIONS FOR MEASUREMENT The OPM100 optical power meter is a single channel, single gain miniature power monitor designed for tight space applications. The unit consists of a receptacled fibre optic input (a free beam option is also available), two free ended supply leads and one free ended signal lead. To make a measurement, proceed as follows: 1. Supply the unit with a clean DC power supply of nominally 5 V (3V minimum, 5.5V maximum). The red lead is to be connected to +5V, the black lead to ground. 2. Connect an optical source to the desired channel via the corresponding receptacle. Ensure...
