Stereoscopic visualization camera and platform

A stereoscopic imaging apparatus comprising:

• a main objective assembly configured to change a working distance along an optical axis to a target surgical site;
• left and right lens sets defining respective parallel left and right optical paths along the optical axis and configured to form the respective optical paths from light that is received from the main objective assembly of the target surgical site, each of the left and right lens sets including:
• a front lens configured to direct the light along the optical path that is received from the main objective assembly,
• a first zoom lens and a second zoom lens that are configured to be movable along the optical axis relative to the front lens, the first zoom lens configured to receive the light from the front lens, the first and second zoom lenses configured to form afocal zoom system for changing a size of a field-of-view of the target surgical site by changing a size of the light propagated along the respective optical path,
• a lens barrel configured to receive the light from the second zoom lens,
• a light filter assembly configured to receive the light from the lens barrel and selectively transmit wavelengths of the light along the respective optical path, wherein the filter assembly includes a plurality of optical filters including at least one of an infrared cut filter, a near-ultraviolent cut filter, and a near-infrared bandpass filter, and
• a final lens configured to focus the filtered light from the light filter assembly;
• left and right image sensors configured to receive the focused filtered light after passing through the respective final lens, the left and right image sensors configured to convert the light into image data that is indicative of the received light;
• and
• a processor communicatively coupled to the left and right image sensors and configured to convert the image data into stereoscopic video signals or video data for display on a display monitor.

• a deflecting element located between the main objective assembly and the left and right front lens of the left and right lens sets, the deflecting element configured to reflect the light received from the main objective assembly to the left and right front lenses;
• a visible light source positioned to transmit light through the main objective assembly to the target surgical site;
• a near-infrared light source positioned to transmit light through the main objective assembly to the target surgical site;
• a near-ultraviolet light source positioned to transmit light through the deflecting element and the main objective assembly to the target surgical site;
• left and right image sensors configured to receive the focused filtered light after passing through the respective final lens, the left and right image sensors configured to convert the light into image data that is indicative of the received light;
• and
• a processor communicatively coupled to the left and right image sensors and configured to convert the image data into stereoscopic video signals or video data for display on a display monitor;
• wherein the deflecting element is coated or configured to reflect only light wavelengths that are beyond the near-ultraviolet light wavelengths range to enable light having near-ultraviolet light wavelengths from the near-ultraviolet light source to pass through the deflecting element to the main objective assembly.
