Wireless Laser Measurements: No Strings Attached

Remember how Pinocchio achieved his dream of becoming “real” when he was finally freed from his strings?

If you need to measure your laser beam’s power or energy, but the usual cable connection between the sensor and the meter is not practical, Ophir’s Quasar may be the right solution for you.

Quasar is a wireless PC interface that connects a sensor to a PC by Bluetooth, a proven and popular interface. Using the Quasar enables working in environments where cables are not an option – for example, in areas which are supposed to be sealed, such as a high power measurement chamber, a glove box or a vacuum chamber, or where cable movement might ruin a delicate alignment.

The Quasar has been approved by the FCC and other regulating authorities around the world.

The Quasar wireless interface connects to most standard Ophir sensors. Using Ophir’s “Smart Sensor” technology, in which all calibration and related sensor data is stored in the sensor’s EEPROM in its “Smart Connector”, the Quasar can be freely hot swapped from one sensor to another. That means 1 Quasar can be used with multiple sensors; it’s not permanently married to 1 sensor.

Quasar broadcasts to your PC over a range of up to several tens of meters, depending on surroundings, and its internal rechargeable battery enables it to keep doing so for over 40 hours.

Together with the Ophir StarLab laser measurement software package, the Quasar turns your PC into a complete laser power and energy work station, with advanced measurement processing, extensive graphical display capabilities, data logging, and much more, able to monitor up to 7 Quasars simultaneously.

The Quasar is now fully supported in StarLab, from version 3.3.


You can also bring laser power and energy measurement to your Smartphone or Tablet via the Quasar, by using Ophir’s “StarViewer” Android app.
