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


     

  • 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.

  • Firmware - Quasar

  • Quasar Reader App
    Quasar reader turns your Android based smartphone into a portable Ophir laser power measurement monitor. It works with Ophir Thermopile and Photodiode based sensors that are attached to a Quasar.

How far can the Quasar really transmit data and can it go through walls?

In actual testing done at customer sites, using the high power option, there was not a place within 100 meters that we could not connect, including going through multiple walls that were made of drywall. The only time we lost transmission was when the walls were made of concrete or we had to pass through some metal doors. With normal labs and offices the signal went right through. In several cases, including a solar power scribing application where windowed doors had to be closed, we were getting a continuous connection as we walked around the spacious building into offices and labs. With the standard range option, the range should be about 1/3 of this i.e. 30 meters.

Which version of StarLab should I use with the Quasar

The Quasar is fully supported in StarLab version 2.40. StarLab 3.00 doesn’t support the Quasar.

At what frequency does the Quasar work? Might there be concerns with interference from other devices?

Quasar runs on Bluetooth, the 2.4-2.5GHz "ISM" band (ISM = Industrial, Scientific and Medical). This is the same band used by WiFi and other technologies. This frequency was chosen as it is available without restrictions around the world. Because other technologies also use it, Bluetooth has to be designed to tolerate interference from other sources. It does this by swapping between 79 channels, at 2.402GHz up to 2.480GHz (each channel is 1MHz). This type of modulation is called FHSS, Frequency Hopping Spread Spectrum. If data does not get through on one channel it retries on a different channel. Other technologies, such as WiFi, use different techniques.

 

This design makes Bluetooth very robust. In principle, if there is another radio transmitter nearby that is using the same 2.4-2.5GHz band AND using the same modulation scheme, interference is a possibility, but not a real likelihood. If the other transmitter is using a different band, there should not be a problem, because there is very little interference produced at other higher or lower frequencies - this is checked during qualification of these devices for CE and FCC in RF test labs.

 

In general, Bluetooth is in common use everywhere, by cellular phone headsets, for example, so interference is not normally a significant risk factor.

Will my Quasar work with my Android device?

Yes, we have an Android app that you can download from the Android Market place to run your Quasar on your Android device. Search for Ophir Optronics Quasar. You need to be running Android 2.3.3 or higher.

Close

How do I pair the Quasar interface with my computer?

If using the Bluetooth radio USB adaptor supplied with the Quasar, the adaptor software should be installed first. Once that is complete, and the StarLab software installation is complete, you are ready to connect the Quasar. You may need to change the discovery settings on your PC to allow the Quasar to connect.
 

To accomplish this, go to the Bluetooth Settings on your PC and ensure you have checked "Allow Bluetooth devices to find this computer".

  • QUASAR Laser power measurement through the air

    QUASAR Laser power measurement through the air

    One of the inconveniences in the measurement of laser power and energy is what to do with the cables connecting the display to the sensor. These cables are of a limited flexibility and they clutter the workspace where the measurement is to be done. Sometimes, due to their stiffness, a motion of the cable moves the sensors and misaligns the set up.

  • Yield Improvement by Online Measurement and Analysis of Laser Energy Using Ophir’s Quasar

    Yield Improvement by Online Measurement and Analysis of Laser Energy Using Ophir’s Quasar

    The Quasar wireless Bluetooth laser power and energy measurement interface allows quick and trouble free installation of complex measurement systems in an existing manufacturing environment, with a minimum of cable laying and disturbance to the facility’s operations.

    This was demonstrated in a project undertaken recently, and is a typical example of what of multi-user systems see in the field.

  • Bridging the Gap between Laser Power Sensors & Your PC

    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

    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.

    Since introducing the first mobile phone power meter app we have been getting a lot of questions about it. Here are some of the more frequent ones:

    • The application does not require “state-of-the-art” phones. It works perfectly OK with 3 year-old HTC Legend (that was not top of the line phone even when it was first announced) and it works well with our test phone which is defined mid-to-low range in today’s phone standards.
    • The software does require android version of 2.3.3 and above. According to latest analysis they account for 65% of current phones (this information comes from google analysis of active phones). Since version 2.3.3 was released in early 2011, almost no new phones are sold with older versions. The contract commitment in the US is usually two years, so most 2.2 and 2.1 phone owners there will probably upgrade to newer phones in the coming months.
