Colposcopes, the gold standard devices for imaging the cervix at high magnfication, are expensive and sparse in low resource settings. Using a lens attachment, any smartphone camera can be turned into an imaging device for tissues such as the cervix. We create a smartphone-based colposcope using a simple lens design for high magnification. This particular design is useful because it allows parameters such as F-number, depth of field, and magnification to be controlled easily. We were therefore able to determine a set of design steps which are general to mobile medical imaging devices and allow them to maintain requisite image quality while still being rugged and affordable.
