Product Description
Function
Stray light blocking: The black matte surface absorbs stray light reflected within the cavity, preventing glare and improving the imaging contrast of the lens.
Multi-channel positioning: The multiple circular holes on the plate are respectively the illumination fiber hole, camera lens hole, and instrument channel hole. These holes align and position the optical fiber, lens, and instrument channel at once, and mount the entire assembly onto the front end of the snake bone.
Fixation and limiting: As the reference gasket for the optical assembly at the front end of the snake bone, it ensures that all channels are coaxial and that the optical path does not shift during bending.
Process characteristics
The surface undergoes blackening and matte treatment; the holes are precisely opened by laser and etching, with no burrs on the hole walls.
It uses a special-shaped profile to fit the internal contour of the first segment of the ultra-thin endoscope snake bone.
It is a core gasket among the optical accessories at the front end of the snake bone, and is assembled as a set with the lens mount and the optical filter.
