FAQ

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.

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 often should I zero my power meter?

For the best accuracy and repeatability, each Ophir meter should be zeroed with no sensor connected periodically. It would not hurt to zero the meter each time it is used, but we recommend to zero the meter at least once a month. See your meter User Guide for the zeroing procedure particular to your meter.

Why wasn’t the firmware upgraded to the latest version when the meter was sent in for recalibration?

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; upgrading the firmware does not affect the calibration.

Can I buy a universal power adapter/charger for my Ophir display?

Yes. We now offer a switching universal power adapter/charger for the Ophir displays. It is part number 7E05029.

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?

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, go to https://www.ophiropt.com/laser--measurement/spare-parts.

  • PC Software & Drivers

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


     

  • 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 VIs for Nova

    VIs gives a complete measurement interface with Ophir's Nova.

System Integrators

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 communication is simple 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

  • Appendix A5 of the StarCom User Manual contains an alphabetical listing and detailed description of all commands available with the Nova, Nova-II, Vega and LaserStar devices.
  • Appendix A4 of the StarCom User Manual gives an example of polling the Nova device for measurements. This was written in VB6.
  • Nova RS232 Assembly (P/N 7Y78105) for use with the Nova device.

Laser Measurements in Materials Processing: How and When They Absolutely, Positively Must Be Made

19th century British physicist and engineer William Thomson, 1st Baron Kelvin, was the first to say, “If you can’t measure it, you can’t improve it.” When applying this principle to improving laser-based processes, there are a variety of parameters that must be measured. Given the continuously rising power of laser systems in material processing, the requirements for measurement systems are more challenging than ever. Which technologies are available to measure high-power lasers? How often should they be measured? What measurements should be tracked? When this data is collected, what should be done with it? Weiterlesen...

How do I know what range, or scale, to set my power/energy meter to? And what happens if I go over range?

Each given range represents one level of gain of an internal amplifier. The electronics, as always, have a limited Dynamic Range. If the measured signal is too low, in other words near the bottom of the range, then it may be lost in the noise and the reading will be inaccurate and noisy. If it’s too high – there may be saturation issues. To give an instrument a usefully wide dynamic range, multiple scales or ranges are used. Switching from range to range can be automatic (“Autorange”), or manual. Autoranging simply starts automatically at the least sensitive range and works its way down the ranges, sampling the signal as it goes, till it finds a range at which the signal is properly detected. Note, by the way, that only in POWER mode is Autoranging available. If we are working in Single Shot Energy mode, there is no Autoranging – simply because when we are measuring a single pulse, the instrument has no opportunity to work its way down the ranges as in Power mode.

5 Situations Where Laser Performance Measurement is Necessary

Measuring the performance of a laser has possible for a number of years and is accomplished with a variety of techniques. These electronic laser measurement solutions give the laser user more relevant, time-based data that shows trends in laser performance rather than single data points. While these solutions have provided laser users with the ability to present data in a simple and easy to understand manner, the application of the data still seems to be unclear to many laser users. Weiterlesen...
