FS: Rubicon Laser Power Meters
And a demo video of it in action:
Features
The Rubicon is based on the Ophir 20C sensor, and has a maximum input power of 5W or 10W. It uses 16-bit A/D conversion with a precision reference, allowing a resolution of 0.1mW (0.2mW for the 10W version). Because they are based on this sensor, the response time is a fast 0.8s to 95% power.
The Rubicon covers the basics that every LPM should have - a reading display, peak power detection, and datalogging. It also has a number of other features that are rather uncommon in a hobbyist LPM.
- Onboard average power display
- Laser stability measurement
- Onscreen graphing
- Graphing in streaming (scrolling, unlimited) or session (will stop after a certain number of readings) mode
- Optional display of an analog needle instead of a graph
- Multiple datastream protocols
- Simple - For use with generic logging programs, like StampPlot Pro
- OpenLPM - For use with Peregrine. In the Rubicon, the OpenLPM protocol is able to pass instructions from the LPM to Peregrine.
- LaserBee - In case someone replaces their LaserBee with a Rubicon, we thought it would be nice to be able to use the software that they already are licensed.
- Multiple baud rate options for compatibility with various datalogging software packages
- Rich integration with OpenLPM-compatible datalogging software
Just an additional note on the datalogger integration - using compatible software, it is now possible to reset a measurement on the computer via pressing the 'Reset' button on the Rubicon. The Rubicon will either just send a reset signal, or can specify a threshold and duration for Peregrine (or other software package) to use. What is sent depends on configuration; see manual for more details.
Here's a screenshot of the graphing screen:

Interface Software
The Rubicon was designed with Peregrine in mind, but will work with other dataloggers. Using the OpenLPM protocol with Peregrine, the Rubicon is capable of instructing the datalogging software to discard the current test and start a fresh one, when the Reset button is pressed. This instruction can use either the default settings already present in Peregrine, or the Rubicon can send a new duration and threshold value to use for the graphing session.
If you are a LaserBee user switching to a Rubicon and have a license to use the bundled graphing software, the Rubicon will support it as long as the LaserBee protocol is used at 9600 baud.
You can also use the Simple protocol to log to programs like StampPlot Pro.
