I have multiple sensors. Do I need a specific meter for each sensor or can I use one meter for all of my sensors?

With Ophir's Smart Head technology sensors can be interchanged between different meters easily. The calibration and setting information is stored in the sensors Smart Head connector so it moves with the sensor to the new meter. It is recommended that you power off your Nova meter before removing the sensor, but the new Nova II and Vega meters detect that a sensor has been removed or attached and will power cycle themselves when doing this.

How does an energy meter measure above the maximum frequency at which it can record every pulse?

The energy meters will then sample at close to its maximum frequency. For instance measuring 10 KHz with a PD10 Sensor and Nova II where the maximum frequency for every pulse on the Nova II is 4 KHz: in this case, the Nova II will pick out pulses at a rate of close to 4 KHz and sample them, i.e. the Nova II will record 40% of the pulses.

What is the Ophir meter zeroing and when should it be performed?

In all Ophir instruments, all adjustments, including zeroing internal circuits, are done from the software. This ensures simple and accurate realignment. The zeroing process helps eliminate internal biases in the unit which could affect accuracy of measurements. It is recommended to re-zero the instrument every 2 months for best performance. Specific instructions for doing this are found in the relevant User Manual for each instrument.

Can I upgrade my Nova-II or Vega software by myself or do I have to send it in to an Ophir distributor?

The Power and Energy Meter's software can be upgraded by the customer using Ophir's StarLab PC application available for download from the Ophir website.

1. Attach the Power and Energy Meters to your PC with the USB cable provided with the Power and Energy Meters.

2. Go to the bottom of the StarLab page and download the firmware for your Power and Energy Meters

3. Run the StarLab application

4. Select your Power and Energy Meters device and press Diagnostics

5. Select your meter and press the Upgrade button

6. Follow all the on-screen instructions to successfully reprogram the display.

 

These instructions, including screen captures, can be found at http://www.ophiropt.com/laser-measurement-instruments/laser-power-energy-meters/software/upgrade-firmware

 

If the field-upgrade process fails (example, unplug of the USB cable during the upgrade), the Power and Energy Meters will not function properly. Therefore, when turning on the Power and Energy Meters the user gets a blank screen. Note: The Power and Energy Meters can still communicate with the PC. Try to reinstall the Power and Energy Meters software as described above.

I’ve upgraded to the latest version of StarLab and my meter no longer is supported. What happened?

Whenever we release a new version of StarLab we add support or deal with various other meter-specific issues. This may necessitate upgrading the meter firmware to the latest release. This release is included in the StarLab package and simply enter the Field Upgrade dialog in order to upgrade your meter to be up to date.

Do I need to recalibrate my instrument? How often must it be recalibrated?

Unless otherwise indicated, Ophir sensors and meters should be recalibrated within 18 months after initial purchase, and then once a year after that.

How do I use the Analog Output of a meter to get a reading of power? And how accurate is it?

The analog output of the meter - using the mating connector provided – gives a voltage signal proportional to the actual reading (it is in fact just a D/A translation of what is being displayed), so it represents a fully calibrated reading. The full scale value is a function of the meter being used and the power range it is on. With the StarBright, Vega and Nova II, for example, the user can select full scale analog output voltage ranges of 1v, 2v, 5v or 10v, and the 100% level of the chosen power scale is scaled to the full scale voltage. For example: if you choose 5V full scale analog voltage range, and your sensor is set to a 50W full scale power range, then you will have 5V = 50W or 0.1 V/W. It will vary according to the chosen power range and chosen full scale voltage range. The electrical accuracy is stated in the specification (see the User manual) as ±0.2% (of reading) ±0.3% of full scale volts (in addition to the calibration accuracy of the sensor’s reading itself).

  • PC Software & Drivers

    This section describes various ways to interface the Ophir meter to your PC as well as the software options available.


     

  • StarLab

    The StarLab application together with an Ophir meter turns your PC or laptop into a full-fledged laser power/energy meter. Supports most Ophir laser power/energy sensors. Up to 8 sensors can be displayed at once on one PC. By using the Ophir COM Object, you can control the device from your own application. Supports the StarBright, StarLite, Juno, Nova II, Vega, Pulsar-1/2/4, Quasar, EA-1 and USBI devices.

  • StarCom

    The StarCom application together with the Ophir meters that utilize the RS232 protocol turns your PC or laptop into a full-fledged Ophir laser power/energy meter. StarCom supports all major Ophir sensors. Supports the Nova, LaserStar, Nova-II, and Vega meters.

  • LabView

    Library supplied for a complete measurement interface with most of our USB speaking devices (StarBright, StarLite, Juno, Nova-II, Pulsar, USBI, Vega). Makes use of our new COM object.

     

  • Nova and VEGA power metersFirmware - Vega / Nova II

    Embedded Software for Vega & Nova II Laser Power / Energy Meters

    Latest Vega, Nova-II firmware (version 2.52)

Besides their use as stand-alone, fully featured laser power/energy meters, Ophir devices are easily incorporated into larger end-user applications. This allows system integrators to leverage Ophir’s excellence in measurement capabilities with legacy analysis packages.
 
RS232
RS232 communication is the simplest to integrate into your OEM application. Integrated Development Environments (IDE’s) such as Microsoft Visual Studio provide functions and methods for accessing the PC’s com port.
 
The following is all that you need to get your RS232 applications up and running

  • User Commands contains an alphabetical listing and detailed description of all commands available with the Juno, USBI, Pulsar, Nova-II, Vega, StarLite, and StarBright devices.
  • Nova II / Vega RS232 cable (P/N 7E01206) for use with the Nova-II and Vega devices (included with the Nova II / Vega).

USB
Ophir provides a common interface for communication and control of all of our USB speaking devices. OphirLMMeasurement is a COM object that is included as part of the StarLab installation (StarLab 2.10 and higher) that allows the system integrator to take control of the Juno, Nova-II, Pulsar, USBI, Vega, StarBright and StarLite devices; integrating them into his in-house measurement and analysis package.
 

System Integrators will need the following components:

  • OphirLMMeasurement COM Object.pdf lists and describes the methods and events available for configuring, controlling and uploading measurements from Ophir devices.
  • OphirLMMeasurement.dll. COM object component developed and supplied by Ophir for communication with the Juno, Nova-II, Pulsar, USBI, Vega, StarBright and StarLite devices. The COM object is registered when the application is installed.
  • OphirLMMeasurement COM Object.pdf describes how to register it on another PC where the Ophir application has not been installed.
  • Nֺova II / Vega USB cable (P/N 7E01205) for use with the Nova-II and Vega devices (included with the Nova II / Vega).
  • Ophir provides example projects of COM Object clients in VC#, VB.NET and LabVIEW. These are found in the Automation Examples subdirectory of our StarLab PC Application.
  • For direct control of the device, refer to User Commands.
