FAQ
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.
CloseAt 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.
CloseWill my Quasar work with my Android device?
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".

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 Ariel, Centauri, StarBright, StarLite, Juno, Juno+, Juno-RS, Nova II, Vega, Pulsar-1/2/4, Quasar, EA-1 and IPM sensor devices.

Videos

This video explains the various items on the StarLab screen, and shows you how to perform basic laser measurements.
Part 1 of a series of video segments teaching you how to use StarLab.

Sometimes we want to not only get a reading, but perform additional processing on the reading. This video shows you how to use various functions in StarLab, such as Averaging, Scale Factor, Normalize, Density, etc.

If all your laser measurement work involves a laptop or a PC, rather than a stand-alone meter, one of Ophir’s direct-to-PC interfaces could be an ideal solution. These are full-fledged Laser Power and Energy meters, but instead of having a separate on-board display, the PC becomes your display. In this video you will learn about the range of PC Interfaces available from Ophir.
The Ophir Quasar is a Bluetooth interface that enables you to connect a laser sensor to a PC, or to an Android smartphone or tablet, without cables.
In this short video, you’ll learn what it can do and how to get started using it.

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.

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.

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