Request InfoMKS Ophir, Light & MeasurementOphir-Spiricon Inc.’s Pulsar-4 multichannel smart head interface for laser meter measurement applications converts a PC or a laptop computer into a full-featured laser power/energy meter. The USB interface eliminates the need for an external display, and the device records pulse energies at up to 20,000 Hz for all four channels simultaneously. The instrument includes an external trigger that measures missing or operator-designated pulses. Proprietary software is included to provide log power and energy, averages, statistics and histograms.See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Mar/Apr 2023 IssuePhotodiode PhotodetectorsExtended 2.6-µm Cutoff InGaAs Photodiode Photodetectors from Marktech Optoelectronics Inc. provide high sensitivity, high speed, and low noise for nondispersive spectrometers, pyrometers, and...BioPhotonics.com March 2024 IssueJoulemeterThe IS50A-1KW-RMT from Gentec-EO is a high-power joulemeter for laser energy measurement up to 1 kW average power.
