  • 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 StarLite, Juno, USBI, Nova II, Vega and Pulsar-1/2/4 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 (StarLite, Juno, Nova-II, Pulsar, USBI, Vega). Makes use of our new COM object.

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

    Latest Vega, Nova-II firmware (version 2.37)

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 use a third party sensor with the Ophir power/energy meters?

No, only Ophir power/energy sensors with the Smart Head connection will work with the Ophir power/energy meters.

Close

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 version 3.00 of StarLab and my Nova-II 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.

  • Power and Energy Meters: From Sensors to Displays

    Power and Energy Meters: From Sensors to Displays

    From the time the first laser was built, physicists probably thought, “That’s great! Now how do we measure it?” Thus laser power and energy meters were born.

    Since lasers are good sources of concentrated heat, it was probably assumed that heat sensing methods would best be employed for measurement. The simplest device to measure heat is a thermocouple. A simple device to measure light is a photodiode. So, some enterprising engineer designed and built such a device. Then they needed an instrument to display the results and give rapid feedback in order to tweak, align, or adjust the laser for maximum output. Early displays were basically analog meters that had a needle on a dial that went from left to right as the laser power went up.

    Laser Power and Energy Measurement

    Ophir standard power and energy measuring heads and displays all use smart head technology. This means that all the configuration and calibration information is stored in a small memory chip inside the smart head plug, so that when the head is plugged into the display the correct power and energy are read. Except for some OEM heads, this technology is used in all Ophir heads: pyroelectric, photodiode, scanned beams, medical heads, etc.

  • Which Laser Power Meter is Right for You?

    Which Laser Power Meter is Right for You?

    We know that sometimes people really do want the all-in-one pen with compass et al, but other times they really just want the basic product. Before StarLite came around, you had two main options for a laser power meter. You could go down the Vega / Nova II route: top-of-the-line meters that can do pretty much anything you can think of doing with your laser power measurement. Then there’s the more basic meters (Nova / Laserstar), which still have some functionality, but are more affordable options for whomever doesn’t need the ultimate laser power meter.

  • How to Measure Different Wavelengths with a Laser Power Meter

    How to Measure Different Wavelengths with a Laser Power Meter

    There’s been some confusion lately about the “laser” setting on an Ophir power meter. Joe will ask: “What if my laser isn’t exactly one of the predetermined wavelengths? Will it still work?” Amanda says, “Can I set the Nova II to 633nm to check how much of that wavelength is in my broadband light source?”
