2103 Newport High-Dynamic-Range (HDR) Power Sensor

The Newport / New Focus 210X High-Dynamic-Range (HDR) Power Sensors are some of the fastest power sensors on the market today. With their high sensitivity and fast speeds, they are ideal for fiber alignment, fluorescence experiments, and absorption spectroscopy anywhere you need a wide dynamic range of up to six orders of magnitude in a single signal trace. With their wide dynamic ranges, these HDR Power Sensors are perfect for observing extremely narrow and deep spectral features.

The logarithmic output is an analog voltage with a range from -0.2V to +3.75V, corresponding to a signal of -74 dBm to +5dBm (40pw to 2.5 mw). This enables the full range of the sensor to be viewed on an oscilloscope screen without having to change oscilloscope settings. Moreover, this output enables a single 14-bit A-to-D conversion to achieve <0.01-dB resolution over the full range.

These HDR Power Sensors are temperature stabilized, resulting in highly accurate and stable measurements. And, unlike other power sensors that slow considerably when switching sensitivity ranges, they incorporate a patented logarithmic-conversion circuit that achieves essentially seamless range switching. This results in a useful dynamic range of >65 dB even at full speeds-about 20-dB better than conventional power sensors. Three user-controllable speed settings are provided so you can further extend the dynamic range if you don't need the speed. The convenient bolt-together modular design and daisy-chained power connections make it easy to connect multiple units for multichannel, rack-mounted or bench-top systems.
