3A-P-FS Very Low Power/Energy Sensor

BFI Optilas is distributing Ophir's 3A-P-FS Very Low Power/Energy Sensor throughout Europe. The product 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°.

The 3A-P-FS measures very low power pulsed or CW lasers in the 0.19 to 20µm wavelength range. The sensor's p-type absorber provides a larger aperture and flatter spectral response than broadband 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-FS very low power/energy sensor works with all BFI Optilas/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 measurement heads.
