ophthalmic Illuminator LED-based design revolutionizes examinations of the cornea; produces a bright, spectrally pure beam of blue light, which causes foreign bodies, abrasions, and other epithelial defects to fluoresce vividly during examinations with fluorescein - the blue beam produced is precisely the wavelength required to maximally excite the dye - since the magnitude of the fluorescence is proportional to both the intensity and spectral purity of the light, the Bluminator yields a clearer, more detailed view of the eye than ever before - the view is enhanced by a 7X magnified image to facilitate detection and diagnosis of corneal injuries and irregularities, streamline contact lens fittings, and speed up treatment - powered by non-rechargeable batteries that provide 3/ 5 year lifespan with normal use
