The old pyro sensors and the newer PE-C sensors are almost identical. The differences between them are as follows:
- More compact
- User Threshold – minimum energy threshold (below which the sensor will not trigger) can be selected according to users' needs
- Measures longer pulses (up to 20ms depending on model)
- Has up to 5 pulse width settings as opposed to only 2 pulse width settings
Smaller size and therefore:
- May need a heat sink (P/N 7Z08267) in order to stand up to higher average powers
- May need a mechanical size adapter (P/N 7Z08273) if it must fit into an existing mechanical jig designed for the older models
Meters and Software Support:
StarLite, Juno, Vega, & Nova II fully support the Pyro-C series. Laserstar, Pulsar, USBI, Quasar, and Nova / Orion with adapter* partially support the Pyro-C series:
- Only 2 of the 5 pulse width settings are available
- Lowest measureable energy cannot be selected (no User Threshold).
StarLab software supports both Pyro-C and older pyro series.
*Note: The PE-C series will only operate with Nova / Orion meters with an additional adapter Ophir P/N 7Z08272 (see details in Ophir website).
Wavelength Setting Names:
If you have your own software for communicating with the sensor, it may be important to note that for some models, the names of the wavelength settings are a bit different between the old pyro and the new PE-C, even though they mean exactly the same thing.
For example, with diffuser OUT, the settings in the PE50BB-DIF-V2 are called “<.8u” (i.e. visible, represented by a calibration point at 532nm that covers the full visible range), and “106” (i.e. 1064nm), while in the PE50BB-DIF-C these same settings are called “532” (i.e. 532nm, the calibration point for the visible) and “1064”.
