FIELD: instrument engineering.
SUBSTANCE: endoscope with deflected remote visual image consists of a rigid tube containing lighting means and observation means, the distal end of tube of which includes deflecting prisms, as well as light guidance means and image transmission means. Two deflecting prisms of lighting means and observation means are located near each other and oriented with the possibility of deflecting lighting beam supplied by guidance means in the direction which is essentially parallel to observation axis of prism of observation means. As per the second version, two deflecting prisms are located in the tube near each other so that lighting axis of deflecting prism of lighting means and observation axis of deflecting prism of observation means basically converge. Between two prisms there installed is a shield resistant to ultraviolet radiation.
EFFECT: designing compact and easy-to-use endoscope with ultraviolet lighting, which prevents trapping of parasite light by observation means.
