A system for material excitation in microfluidic devices is described. Aspects of the invention resemble a submerged periscope when in use. They allow for light to be redirected along a more advantageous trajectory as does the maritime device. A prism with a reflecting surface may be used to direct a laser beam along one or more microfluidic trenches or channels. Alternatively, a reflecting surface may be provided in connection with a simple support. Directing a beam along multiple paths is preferably accomplished by scanning a single laser across or around the reflecting surface provided. Provision may be made for at least a portion of the submersible used to function as an electrode to assist in electrokinetically driving fluids and/or ions within the microfluidic device.

Periscope Swim Goggles are swimmer's goggles with a periscope situated above the water line that projects the view that is ahead of the swimmer through a fiber optic cable to a viewer located on the goggle's eyepiece. Generally, an open-water swimmer using the free style or crawl stroke must occasionally sight on a landmark to swim toward. Periscope Swim Goggles would enable the swimmer to continually swim directly along the desired path without lifting the head for sighting. Conventional swimming goggles are typically comprised of two eyepieces contoured and gasketed for an air-tight fit around each eye socket and an elastic strap that wraps around the head holding the eyepieces tight to the face. In one embodiment of the invention, the periscope is positioned and secured at the back of the head by the elastic strap of the goggles. The fiber optic cable leaves the periscope and follows the elastic strap to the viewer which is mounted to the front of the eyepiece.
