70100 In Stock

The 70100 by Newport is a Single Channel Merlin Control Unit that is an integral component within the overarching Merlin System. This comprehensive system encompasses the control unit itself, detector(s) paired with a preamplifier, and an optical chopper. Upon the detector's connection to the control unit, Merlin's sophisticated functionality immediately identifies the detector and proceeds to download its corresponding calibration data. The 70100 Merlin software harnesses the power of digital signal processing to attain the highest levels of precision and stability. The Smart Ranging feature allows for a seamless gain-switching experience. This control unit also boasts true digital lock-in capabilities, facilitated by a robust signal processing computer entrusted with the tasks of demodulation and filtering.

The 70100 drives the optical chopper and operating as a lock-in amplifier. Its role extends to signal retrieval and the rejection of unmodulated background radiation. Critical to its operation is the utilization of previously loaded calibration data to compute signal values, which are subsequently displayed in user-selected units. The Smart Ranging feature further simplifies measurements by automatically configuring gain settings. A remarkable attribute of the 70100 is its wide dynamic range, comprising a multistage, low-noise amplifier chain, which undergoes sequential sampling at each stage numerous times during each cycle. This meticulous process ensures that the highest unsaturated voltage is employed for both analog and digital conversion, thereby optimizing the utilization of the A/D system's resolution for every reading.
