Ophir-Spiricon Inc. has introduced the 3A-P-FS, a very low power/energy sensor designed to measure very low power and energy light sources and divergent beams such as LEDs and diode lasers. It features a 12-mm numerical aperture and a fused silica window in front of the detector. The window is 7 mm from the sensor surface and keeps out air currents and long-wavelength background heat, enabling accurate measurements. The sensor measures divergent beams up to ±40° and pulsed or continuous-wave lasers in the 0.19- to 20-μm range. Its p-type absorber provides a larger aperture and a flatter spectral response than do broadband devices. Optical power can be measured from 60 μW to 3 W and energy, from 20 μJ to 2 J.
