ABSTRACT:
A probe apparatus in combination with an endoscope includes a confocal laser probe for in-vivo imaging. The probe is insertable through a forceps channel of an endoscope, and has an optical unit. There is a lens barrel. Plural lens optics are mounted in the lens barrel. The plural lens optics include first lens optics disposed on an object side, and opposed to an object within a body. An optically inactive surface is formed with the first lens optics, and has at least one portion protruding from a barrel end surface of the lens barrel on the object side. Preferably, a height difference of protruding the optically inactive surface from the barrel end surface is 10-500 microns. The portion of the optically inactive surface protruding from the barrel end surface is coated with adhesive agent, for adhesion of the first lens optics thereto.
