This section describes various ways to interface the Ophir meter to your PC as well as the software options available.
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.
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.
How can I control Ophir USB speaking devices from the PC?
All USB speaking devices (Juno, Pulsar and USB as well as the Vega and Nova-II Power and Energy Meters) can be controlled via our StarLab. This provides full remote control and measurement capabilities. In addition, system integrators can make use of the OphirLMMeasurement COM object for all of our USB speaking devices that are included in the application installation. Documentation and Examples in Visual Basic, LabVIEW are found in the "Automation Examples" sub-directory of your StarLab directory.
Note: ActiveX components (UsbX for USB Interface, Vega, and Nova-II; FastX for Pulsar) are still provided for legacy systems but do not support the latest features (no Juno support, no Windows 7 support)
For our legacy LabVIEW community of developers we continue to supply the Ophinstr and DemoForPulsar libraries to get your LabVIEW VI solution started.Close
What is the maximum number of sensors that can be connected via USB to one PC?
The StarLab can support up to 8 sensors simultaneously. This can be through attaching 8 sensors to 8 different USB Interfaces, 8 sensors to 2 Pulsars or any combination in between. Note that when working with a large number of devices you may run out of ports on the PC. In that case, you must use a USB compliant Hub.Close
What is the difference between the StarCom and StarLab PC applications?
StarCom is our legacy PC application which connects via RS232 (not USB), for those Ophir instruments having RS232 interface capability (Vega, Nova II, LaserStar and Nova). It performs all basic functions such as real-time data logging, saving data in PC file, off-line data viewing, printing, etc. For a relatively new computer, you'd have to check that it has a serial port to which to connect the meter. The last release of StarCom was in 2008, with all that this implies. StarCom should nevertheless be able to work on a Win7 32 bit PC. More information, including software download, is available at http://www.ophiropt.com/laser-measurement-instruments/laser-power-energy-meters/software/starcom.
StarLab is our full-featured PC application that connects via USB to all Ophir USB-speaking instruments (Vega and Nova II meters, as well as Juno, Pulsar, USBI and the Bluetooth-enabled Quasar PC interfaces). In addition to all basic measurement and data logging functions, it also offers a wide range of special functions (including user-defined mathematical functions), multi-channel operation, COM Object for integration with external systems, etc. More information, and software download, is available at http://www.ophiropt.com/en/laser-measurement-instruments/laser-power-energy-meters/software/starlab.Close
How can I interface my Ophir Power Meter (Juno, USBI, Pulsar, NOVA II, Vega) to LabVIEW?
For customers using the new LabVIEW COM Demo, there is nothing additional to do. Just open it and get started. If writing your own LabVIEW application, make sure that the OphirLMMeasurement COM Object is included in your LabVIEW application
For customers using the legacy OphInstr LabVIEW package, here are additional clarification steps to assist establishing the interface to LabVIEW when connecting an Ophir meter such as the USBI/Nova II/Vega with the USB.
The sequence for preparing to interface the Ophir USBI (or meters connected through USB) with LabVIEW is generally as follows:
BE SURE the OPHIR CD is NOT in the PC CD drive when running SWAPINF.
- Disconnect any USBI OPHIR Device from the PC
- Run SwapINF utility
- Set LabVIEW option On
- Press "Swap" button - You will be prompted to "Remove the Ophir USBI Devices before continuing"
- Press "OK" (you have already removed these)
- Press "OK" again (after SwapINF is done)
- Reconnect the Ophir USBI device to the PC that you wish to apply LabVIEW VI's on If asked by Wizard (i.e. in XP) to update software etc.
- Select "not this time" & press "next" button
- Again, press "next" (install software automatically)
From here on you may apply LabVIEW VI's on your deviceClose
I see that you have a new version of StarLab software available, version 2.40, that turns you PC into a laser power/energy multi-channel station. What's so great about it and why should I upgrade?
We have recently introduced 64 bit StarLab 2.40 application software (also compatible with 32 bit).
This software package is free, and when combined with our USB-capable meters such as Vega or Nova II, or our USB based PC interfaces such as Juno, Pulsar and USBI, it is the ultimate in live data viewing, collection and analysis of laser power and energy measurements. If you want to go wireless, use it with our Bluetooth enabled Quasar.
StarLab is a standalone software package that is very modular. Use it with up to 8 instruments or PC Interfaces to display and collect data from all 8 simultaneously. You can perform math functions for ratiometric measurements such as A/B, and math functions like A-B, A+B, or A *B. Display all on one coordinate system with a different color for each, or split them into several windows. View data in Line, Bar Graph, Histogram, or for tuning up one channel use our simulated analog meter with or without hysteresis. Get Live Statistics like Min, Max, Avg, and Std. Dev, or select batch size for stats.
Measure power and/or energy density , based on user defined beam size.
Time-synched multi-channel logs to a single log file for later review.
LabVIEW and Active X support.
If you have one of our instruments with USB or our USB interfaces download it for free now and try it out. There is no need to uninstall older versions of our USBI program if you are already using them and just want to try this out. If you don't have one of our instruments or USBI interfaces contact us, and set up a free demonstration in your lab or production floor. Here's the link to download it: You'll Love It like I do.

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.
Bridging the Gap between Laser Power Sensors & Your PC
Essentially, a PC interface is simply a power meter without the display. This might seem strange if you look at a power meter as only a way to display the laser power or energy reading that your sensor provides. However, as you might know, a power meter (and PC interface) needs to be calibrated. It isn’t just a display or connection. The real purpose of the meter is to convert the raw analog signal from the sensor – very precisely – into a digital reading which can be then used either in a power meter display or PC software, like StarLab.
Using COM to integrate Ophir Meters into your own PC-based Photonics Application
Ophir’s world renowned StarLab application turns a PC into a laser power/energy multi-channel analysis workstation.
However, StarLab is a closed environment that works with Ophir Power Meters only. Let’s say you have an application in which you need to integrate a laser, an Optical setup on a 3-axis motorized stage, and power measurement of that laser’s beam before and after it passes through the optics, all within one application that you write custom made for your own purposes. You’ll use software drivers provided by the various vendors and your own business logic for your application. This paper describes how to use the COM object that we provide in order to drive our Power Meters in your application.
Longer Length Sensor Cables
The Ophir sensors are provided with a 1.5m cable between the sensor and the smart head connector. When a longer length cable is needed it can be provided, as long as it is within operational limits. However it is not possible to add an extension to the cable, because that moves the smart head connector away from the meter or interface unit which can degrade the smart head functionality or disable it.
