High-Dynamic-Range
Power Sensors
Models 2101 & 2103
These power sensors are sensitive to electrostatic
discharges and could be permanently damaged if
subjected even to small discharges. Ground your-
self adequately prior to handling these detectors or
making connections. A ground strap provides the
most effective grounding and minimizes the
likelihood of electrostatic damage

The fast analog response is also useful for viewing high-range signals on an oscilloscope, making the Model 2101 and 2103 good tools for general lab use. Multiple units can be bolted together and their power Models 2101 & 2103... -

For the Model 2101, a 3.5-V output typically corresponds to approximately 2 dBm of input optical power at 920 nm. - Page 7 <0.02 dB. The typical wavelength dependence of the response is shown in Figure 1 for Model 2101 and Figure 2 for Model 2103, respectively. The vertical axis is in optical dB, and the horizontal axis is in optical wavelength µm.
- Page 8 Model 2101 has no status light. Output Signal The output of the Models 2101 and 2103 is an analog voltage with a gain of 50 mV per dB of input light. For Model 2101, a 3.5-V output corresponds to approximately 2 dBm of input power at 920 nm;...
- Page 9 Measurement Speed The Models 2101 and 2103 have three filter settings (1, 5, and 25 kHz) to reduce noise when speed of response is not critical. The fastest setting results in a 0-100% small signal rise time of 30 µs and an analog bandwidth in excess of 25 kHz.
- Page 10 Noise Levels The electrical noise voltage present at the output divided by the gain (50 mV/dB) of the power sensor represents the noise referred to the input. A plot of this is shown in Figure 4 for the 25-kHz filter setting. Note the discontinuity at the crossover.
