Our MI-Series miniature interferometers equipped with corner-cube retroreflectors are designed for incorporation into customer-supplied systems and used for making precision length measurements. Their layout and operation may be readily adapted to suit specific applications. Their miniaturized sensor heads and corner-cube retroreflectors allow using them as permanently installed metrological systems. Their fiberoptic-coupled sensor heads provide major benefits in many types of application and improve the flexibilities of overall systems.
Their miniature interferometers convert translations of their retroreflectors into optical-interference signals that are transmitted

to their optoelectronic signal-processing and power-supply units for conversion into lengths and output to external devices. Their He-Ne lasers, which are frequency-stabilized on those models intended for handling length ranges, and their corrections for environmental influences on laser wavelength form the bases for their high metric precisions.The systems themselves have no linearity errors. System operation and display of measurement results may be via either an external display unit or a PC running an optional software package.
