Avo Photonics of Horsham, Pa., a Halma company, has provided system design and manufacturing services for Philadelphia-based Optofluidics Inc.’s molecular NanoTweezer system. The NanoTweezer is made up of three components: a microscope flow system that sits atop the microscope platform, removable waveguide chips inserted into the flow system, and a benchtop control unit. It allows users to isolate objects more than 10 times smaller than those trapped by traditional optical tweezers. Avo provided the design and production of disposable assemblies consisting of three single-mode, polarization-maintaining fibers hard-coupled to a NanoTweezer chip. Avo also created the means to tune the wavelength and control the power of the laser.
