A stereo colposcope having variable linearity filter systems for both the excitation step and the suppression step, and can be used universally with any fluorescent compound or drug, as is the case of photodynamic diagnosis (PDD). The colposcope is a two-way colposcope because the treatment can be administered by an optical system or by a light-producing radio-frequency electrical current with a diathermic effect which facilitates photodynamic treatment. The colposcope produces ozone, which has an antiseptic effect when applied to the genital tract. A monitor provides for three-dimensional viewing through the use of two video cameras with the DLP (Digital Light Processing) and HDTV (High Definition Television) systems with the use of active lenses.
