At the Fletcher Lab at the University of
California, Berkeley, has designed equipment to turn the camera of a
standard cell phone into a diagnostic-quality microscope with a magnification
of 5x-60x. Cell-phone microscopy enables visualization of samples, followed by
capture, organization, and transmission of images critical for diagnosis. This
technology is applicable in a wide range of applications beyond
diagnostic medicine. The team has developed a suite of devices to image
everything from sub-micron bacteria to the surface of the eye.
See” Cell-phone
Based Platform for Biomedical Device Development and Education Applications”
where “we report the development of two
attachments to a commercial cell phone that transform the phone's integrated
lens and image sensor into a 350× microscope and visible-light spectrometer.
The microscope is capable of transmission and polarized microscopy modes and is
shown to have 1.5 micron resolution and a usable field-of-view of 150×150 microns^2 with no image processing, and approximately 350×350 microns^2 when post-processing is applied. “
