BFi Optilas has announced that it is now distributing the 3A-P-THz power/energy sensor produced by Ophir. The 3A-P-THz is designed to measure THz light sources from very low power to very high power, up to 3W, which the company claims is 30-times the power level measurable by competing products. The sensors are calibrated to read THz radiation at the PTB national metrology institute in Germany, with traceability available.
The sensors are capable of measuring short pulse or CW lasers in the 0.1-10THz wavelength range. The sensor's p-type absorber provides a larger aperture and flatter spectral response than most similar devices, maximising performance across the entire spectral range. Optical power can be measured from 60µW to 3W, and energy from 20µJ to 2J. The 3A-P-THz is less expensive than traditional systems and is compatible with all Ophir meters and PC interfaces.
