How to choose a Preamp for your IR Detectors

1. Determine the detector you intend to purchase.
2. Determine the highest frequency you expect to see or the system chopping frequency.
3. Multiply the highest frequency or the chopping frequency by 10 if you want to resolve the waveform cleanly.
4. Consult our table of available preamps. Normally select a DC-coupled preamp for use with photovoltaic devices or an AC-coupled preamp for use with photoconductive devices, or consult us.
5. Consult us if you need customized bandwidth or special gain for your preamp. We routinely customize.
