The NanoHarp 250 is a data acquisition board for multichannel scaling or photon counting. The NanoHarp 250 is an ideal instrument for the acquisition of fluorescence or luminescence decays on the nanosecond to millisecond time scale. Other applications include Optical Time Domain Reflectometry (OTDR), Time-of-Flight mass spectrometry and range finding. The board provides two time bin resolutions of either 4 ns or 32 ns, which can be binned on board resulting in a maximum usable time span of 1.04 ms resp. 2.15 s. The boards' multi-stop capability allows efficient recording of long-lived fluorescence decays up to the millisecond time range with correspondingly slow excitation rates. On-board histogram memory is 18-bits deep, allowing the collection of 262144 counts per bin without software intervention.
