Modular Electronics ORTEC was a pioneer in the early development of modular nuclear electronics. In particular, we were leaders in the development of NIM instruments since the inception of the NIM standard in the 1960’s. Today, there can be scarcely a single physics research laboratory in the world which is not a user of ORTEC NIM instrumentation. The modular concept and the availability of a broad range of functions within the modules themselves enable virtually unlimited configurations of nuclear measurement systems to be implemented. The ORTEC range of modular electronics includes instruments in the NIM and CAMAC formats as well as other modular instruments such as photomultiplier bases, preamplifiers and other accessory instruments. Functionally speaking, modular instruments for pulse height spectroscopy, fast timing, counting, supply of power and high voltage and other special functions are all available from the broad ORTEC range. Selection guides and information on the more usual configurations are provided in the library section of this web page.
