LabVIEW Libraries for LaserStar Dual Channel


Ophir LabVIEW VIs for Dual Channel LaserStar ver 3.10
The Ophir VIs gives a complete measurement interface with Ophir's Dual Channel LaserStar device.
Note: The Ophir VIs require the VISA library of LabVIEW.



I see that you have several LabVIEW packages. What is the difference between them?

Libraries for Nova and LaserStar were developed in LabVIEW 6.1. They have been tested and found compatible with LabVIEW 7.0 and LabVIEW 8.6.1 as well.

The library for Nova-II, Vega, and Juno support (OphirInstr) was developed in LabVIEW 8.6.1 and has been tested with NI-VISA 4.6.2. It also includes support for the Single Channel LaserStar. This has been tested in LabVIEW 2009 as well. 

The library for Pulsar support (DemoForPulsar) was developed in LabVIEW 7.0 and tested in LabVIEW 8.6.1 as well.

The new LabVIEW COM Demo that supports the Juno, Vega, Nova-II, Pulsar devices was developed in LabVIEW 8.6.1 and has been tested in LabVIEW 8.6, LabVIEW 2009 and LabVIEW 2013 as well.


Using your LabVIEW VIs, I have followed all of the instructions and receive the error "1301" etc.

Device responses take the form 1.234 (a period distinguishes between the integer and fractional part of a real number). This may not match the settings of the computer upon which the VI is running. For example, many European countries use a comma (",") in place of a period (1,234). This causes the LabVIEW VI to not "understand" the devices's response.
(Go to the section on Period and Comma Decimal Separators for National Instrument's explanation) 

Solution: LabVIEW allows the User to override the local regional settings of the computer within the LabVIEW environment. To do so

1. Open LabVIEW
2. Select Menu >> Tools >> Options
3. Select Front Panel in the ListBox
4. Deselect Use localized decimal point*

5. Close LabVIEW
6. Open LabVIEW and run the Ophir Instrument VIs



How do I download and work with LaserStar Dual Channel VIs?

  • Download LaserStar Dual Channel VIs (744 KB) and run it.
  • This will run the WinZip Self-Extractor and default to unzip the Dual Channel LaserStar VI's to "C:/Program Files/National Instruments/LabVIEW 6.1/instr.lib". To select a different target folder, press the "Browse" button.
  • Press the "Unzip" button to complete the self-extraction process.
  • Press "Close" to close the session.
