New Tools for Laser Beam Characterization

Electro Optical Components will launch new products for laser beam characterization at Photonics West 2015 in San Francisco (7-12 Feb.). Photonics West, organized by SPIE, is the leading fair in optics and photonics with 1,250 exhibiting companies and 20,000 attendees. EOC will present the gSKIN® Laser Power Sensor portfolio and two new product classes for laser beam characterization: Laser Power Heads and Laser Positioning Sensors. Both products will be launched at Photonics West 2015.

Fast Laser Power Heads

The Laser Power Head enables fast and easy measurement of average laser power. EOC already offers laser power sensors, but with the forward integration of the sensors into a power head, measurements and data read-out will be easier. EOC's sensor technology has been tailored to the new product, allowing laser powers up to 50 Watts to be metered with a non-accelerated response time of less than 250 milliseconds. The fast response time allows higher productivity and throughput as well as higher measurement frequencies for increased process control.

The power head operates with an input voltage of 12 to 24 Volt and delivers a calibrated and normalized voltage signal from 0 to 10 Volts. There are three versions for laser powers of 5W, 10W and 50W. Other laser powers ranges are available upon request. Each power head is equipped with cooling for high power applications. 

Thermal PSD for OEMs: Laser Position and Power Sensors for 190nm-15µW

With thermal PSDs, acquiring and processing precise data on power and position of laser beams is simple. The Laser Positioning Sensors are designed for powers as low as 100 µW   up to 50 Watts. Since they use greenTEG's thermoelectric technology, saturation problems and wavelength dependent sensitivity are not an issues. Sized at 18x18mm they will suit most requirements.

Sensor technology

These laser power sensors are based on the thermopile technology. A novel production process allows them to produce sensor modules of a thickness of only 0.6mm. They can measure laser power from  deep-ultraviolet to the mid-infrared range with a rise time of less than a second and a resolution below 1µW. Thermopile sensors for laser power measurements are especially suited when measuring in a broad dynamic range and when monitoring average power.  Further technical details about these laser power sensors is available at
