I purchased a Single Channel Centauri, yet it has an additional sensor input socket labelled Channel B. How do I get this second input to work so that I can attach, measure and compare with two sensors simultaneously?

The Single Channel Centauri is actually a Dual Channel Centauri with the second Channel B disabled.
You can field upgrade a Single Channel Centauri to a Dual Channel Centauri by purchasing a Dual Channel Activation Code, ordering P/N 7Z11056.
The code number received is then entered by the user in the Instrument Settings to enable the second channel.

I don't see my exact wavelength in the wavelength option for my Ophir sensor. I only see several wavelength ranges. What should I do?

Select the range that contains your wavelength. The sensors have coatings on them that have been characterized and for any wavelength within that range the sensor will be within calibration tolderance including variations in sensitivity within that range. When there is a difference in sensitivity that exceeds the allowable tolerances, a new wavelength range is created and a calibrated for.

I can understand why a power meter sensor needs to be recalibrated, but why do I have to have my Power and Energy Meters recalibrated?

Think of it like a voltmeter or ammeter, these have to be recertified/recalibrated as well like most other pieces of test equipment. In general, our instruments are unlikely to drift or fail over time like a sensor might that is constantly exposed to laser energy. But the possibility exists. So the general practice in our industry is to have Power and Energy Meterss recalibrated and recertified as well. ISO standards and FDA, as well as other agencies, require both be recalibrated and recertified.

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.

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).

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. To view or download a copy of the meter User Guides, follow this link: https://www.ophiropt.com/laser-measurement-instruments/laser-power-energy-meters/services/manuals.

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.

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.

Which types of USB Flash Drives are suitable for use with the Centauri?

For firmware upgrade and logging purposes, use USB Flash Drives of up to 32GB storage capacity, formatted as a FAT32 file system only. (Not exFAT nor NTFS).
Larger capacities, or differently formatted USB Flash Drives will not work with the Centauri.

    Notes
    : Firmware update is performed by downloading the files into a USB Flash disk from Ophir website and connecting it to the Centauri (see link above).
    The firmware can't be updated via StarLab.

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
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, Juno+, USBI, Pulsar, Centauri, Nova-II, Vega, StarLite, and StarBright devices.
  • Centauri RS232 cable (P/N 7E01213). Included with the Centauri.

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, Juno+, Nova-II, Pulsar, USBI, Vega, Centauri, 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, Juno+ Nova-II, Pulsar, USBI, Vega, Centauri, 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.
  • Standard micro-B USB cable (P/N 7E01279) for use with the Centauri device (included).
  • 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.
