Compact, Low-Cost Optical Power Meters for Photonics Alignment Provide High Bandwidth

The F-712.IRP1 and its two channel sibling, the F-712.IRP2, convert optical signals in the 600 nm to 1700 nm range with optical power from 230 picowatts to 1.3 milliwatts into an analog output voltage of 0.1 V - 1.6 V. In order to be useful for fast optical alignment systems, the output signal conversion is logarithmic and optical power changes can be detected and converted with a bandwidth of 6 kHz.
