LOGAN, Utah, Jan. 24, 2011 — Ophir Photonics has announced the 3A-P-THz power/energy sensor designed to measure terahertz light sources from very low power to very high power, up to 3 W, 30 times the power levels of competing products, according to the company. It is traceable to standard laboratory calibration. A standard sensor head, it is less expensive than traditional systems and is compatible with all of the company’s meters and PC interfaces. Calibrated to read terahertz radiation at the PTB national metrology institute in Germany, it measures short-pulse or continuous-wave lasers in the 0.1- to 10-THz wavelength range. The sensor's p-type absorber provides a larger aperture and flatter spectral response than most similar devices, maximizing performance across the entire spectral range. Optical power can be measured from 60µW to 3 W, and energy from 20 µJ to 2 J. The power/energy sensor works with all Ophir smart displays or PC interfaces, including the Orion PE, Nova, Nova II, Vega, LaserStar, USB 1, 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. The instrument is available now, with OEM pricing available upon request.
