Endomicroscope Controls

• The tip of the endomicroscope is placed in gentle contact with the tissue
• Laser light from the confocal scanning insert is projected and focussed to a fixed point
• Buttons on the endoscope control body are used to move the position of the focal plane within the tissue
• As the confocal scanning insert moves back within the endomicroscope tip, laser light is focussed to a point near the tissue surface
• The confocal image plane is in a position near the surface of the tissue
• When the confocal scanning insert moves forward within the endomicroscope tip, laser light is focussed to a point deeper in the tissue
• The image plane is positioned deeper in the tissue
• The pressure or position of the endomicroscope tip against the tissue remains unchanged when adjusting imaging depth
