A method for fabricating a transducer suitable for a fluidic drive for a miniature acoustic-fluidic pump or mixer that includes an acoustic transducer attached to an exterior or interior of a fluidic circuit or reservoir. The transducer converts radio frequency electrical energy into an ultrasonic acoustic wave in a fluid that in turn generates directed fluid motion through the effect of acoustic streaming. The method includes depositing a piezo-electric thin-film onto a platinum coated silicon wafer or substrate with capping electrodes, defining each separate transducer; and dicing said piezoelectric tin-film to provide individual transducers.

Method for fabricating a transducer

The fluidic drive for miniature acoustic-fluidic pump and mixer is comprised of an acoustic transducer attached to an exterior or interior of a fluidic circuit or reservoir. The transducer converts radio frequency electrical energy into an ultrasonic acoustic wave in a fluid that in turn generates directed fluid motion through the effect of acoustic streaming. Acoustic streaming results due to the absorption of the acoustic energy in the fluid itself. This absorption results in a radiation pressure and acoustic streaming in the direction of propagation of the acoustic propagation or what is termed &ldquo;quartz wind&rdquo;.

A scanning monochromator is disclosed which is capable of operation over a wide bandwidth in an ultra-high vacuum. The monochromator includes a pair of carousel assemblies carrying the optical elements which may be independently positioned translationally along the optical axis of the instrument and also rotationally, which each positioning control operable from outside of the instrument. A carousel on each of the carousel assemblies carries several optical elements and is rotatable to change which optical element is used, also from outside of the instrument.
