Video microscope

A video microscope comprising:

• an observation stand forming an elongated enclosure having an inner surface and two open ends, one of said ends facing an observed object;
• an illuminating light source positioned on the inner surface of the observation stand to light the observed object;
• a lens barrel having a lens system at one end and slidably fitted in said observation stand through an open end of said observation stand opposite said open end facing said object;
• said lens system being positioned on an image pickup optical path of the observed object;
• said lens barrel having another end opposite said end slidably fitted in said observation stand, being open;
• a video signal converting section including a cylinder;
• said cylinder of said video signal converting section having a two-dimensional CCD element aligned along said optical path and having a driving circuit for driving said element, said cylinder being slidable through said another open end of said lens barrel;
• an objective distance adjusting mechanism arranged between said observation stand and said lens barrel to adjust a distance between the observed object and an objective side of said lens system;
• and
• an enlargement/reduction magnification and focus adjusting mechanism arranged between said lens barrel and said cylinder of said video signal converting section to vary and adjust enlargement/reduction magnification of said lens system and adjust focus of said lens system.
