Ophir-Spiricon Announces New Power/Energy Sensor For Measuring Very Low Power And Energy, And Divergent Beams

Logan, UT – Ophir-Spiricon, the global leader in precision laser measurement equipment, recently announced the 3A-P-FS Very Low Power/Energy Sensor. The 3A-P-FS is designed to measure very low power and energy light sources and divergent beams, such as LEDs and diode lasers. The 3A-P-FS features a wide, 12mm numerical aperture and a fused silica window in front of the detector. The window, only 7mm from the sensor surface, keeps out air currents and long wavelength background heat, allowing more accurate measurements of lower powers. The sensor can measure divergent beams up to ± 40 degrees.

The 3A-P-FS measures very low power, pulsed or CWlasers in the 0.19 to 20 µm wavelength range. The sensor's p-type absorber provides a larger aperture and flatter spectral response than broadband devices, maximizing performance across the entire spectral range. Optical power can be measured from 60µWto 3W, and energy from 20µJ to 2J.

"There has been an explosion of applications for very low power, divergent light sources, such as LEDs and diode lasers," stated Ephraim Greenfield, VP Engineering, Laser Measurement Group, Ophir-Spiricon Inc. "But most low power detectors recess the sensor well below the surface, making them unsuitable for divergent beams. Our engineering team understands that no single absorber can meet the all needs. Thus we have developed a number of types optimized for different applications. The 3A-P-FS makes use of a unique, fused silica window only 7mm from the 12mm diameter absorbing surface. This ensures accurate measurement of lower powers and more divergent beams."

The 3A-P-FS very low power/energy sensor works with all Ophir smart displays or PC interfaces, including the Orion PE, Nova, Nova II, Vega, LaserStar, USBI, Pulsar, and Quasar. Each display features a "Smart Connector" interface that automatically configures and calibrates the display when plugged into one of the company's measurement heads.
