PC Software & Drivers
This section describes various ways to interface the Ophir meter to your PC as well as the software options available. Check out the datasheet for more details.
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 Ariel, Centauri, StarBright, StarLite, Juno, Juno+, Nova II, Vega, Pulsar-1/2/4, Quasar, EA-1 and Ariel 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 (Centauri, StarBright, StarLite, Juno, Juno+, Nova-II, Pulsar, Vega). Makes use of our new COM object.

Introduction to the StarLab Laser Measurement Application
This video gives an overview of the StarLab application and its various functions. Part 1 of a series of video segments teaching you how to use StarLab.
Frequently Asked Questions
How does an energy meter measure above the maximum frequency at which it can record every pulse?
- Answer
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 how often should I zero my power meter?
- Answer
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 and repeatablity of measurements. It is recommended to re-zero the instrument every month or two for best performance. Specific instructions for doing this can be foundin the User Guide/Manual for each instrument.
Can I use a third party sensor with the Ophir power/energy meters?
- Answer
No, only Ophir power/energy sensors with the Smart Head connection will work with the Ophir power/energy meters.
I have multiple sensors. Do I need a specific meter for each sensor or can I use one meter for all of my sensors?
- Answer
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.
Can I upgrade my Nova-II or Vega software by myself or do I have to send it in to an Ophir distributor?
- Answer
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.
- Attach the Power and Energy Meters to your PC with the USB cable provided with the Power and Energy Meters.
- Go to the bottom of theStarLab pageand download the firmware for your Power and Energy Meters
- Run the StarLab application
- Select your Power and Energy Meters device and press Diagnostics
- Select your meter and press the Upgrade button
- Follow all the on-screen instructions to successfully reprogram the display.
These instructions, including screen captures, can be found at Upgrading Instrument Fireware tutorial.
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?
- Answer
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.
How do I use the Analog Output of a meter to get a reading of power? And how accurate is it?
- Answer
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 1, 2, 5or 10 V,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 50 W full scale power range, then you will have 5 V = 50 W 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).
Do you want to see some of the functionality of a power meter with different sensor types?
- Answer
You can try our Nova II demo online. It can be found here. You can use this demo to connect to different sensor styles and check the meter’s and sensor’s functionality. You can also simulate a laser by imputing exposure levels. This simulator does not allow you to try every sensor, but it can give you an idea how the meters work and how sensors interface with the meter.
Do I need to recalibrate my instrument? How often must it be recalibrated?
- Answer
Unless otherwise indicated, Ophir sensors and meters should be recalibrated within 18 months after initial purchase, and then once a year after that.
Can I buy a universal power adapter/charger for my Ophir display?
- Answer
Yes. We now offer a switchableuniversal power adapter/charger P/N
7E05029 for the Ophir displays.
My meter seems to be charging normally, but it lasts for less than an hour on battery power. Does the battery need to be replaced?
- Answer
Yes, the battery needs to be replaced. A new battery should last 8 hours per charge. We recommend that you send the meter back for battery replacement and recalibration. User battery replacement is possible. For battery part numbers and ordering information, check out theSpare Parts.
Why wasn’t the firmware upgraded to the latest version when the meter was sent in for recalibration?
- Answer
Our recalibration process is to not automatically upgrade the firmware in meters when they are sent in for recalibration, unless specifically requested to upgrade it. The reason for this is that we support many companies, such as medical companies, that have equipment validation processes that don’t allow changing the firmware version from the currently validated version. If you do want the latest firmware version installed, we will do that at no additional charge (for meters which are upgraded electronically) if it is specifically requested on the RMA request checklist form. For older meters (such as the Nova) that are upgraded through changing the EEPROM, a nominal fee is added, if firmware upgrade is requested. Note that upgrading the firmware does not affect the calibration.
Why doesn’t the StarLab software recognize the Nova II or Vega meter when a RS232 to USB adapter cable is used with the supplied RS232 cable for an interface?
- Answer
Unfortunately the interface described above is not sufficient to establish the correct communication protocol for the computer USB to interface to the Nova II or Vega meter. The original USB cable (one is provided with each Nova II and Vega meter) is required for the StarLab software to communicate OK. The USB cable is P/N
7E01205 and is available to order.
