[Lighting of biological objects during their visual recording by super thin rigid endoscopes]

The paper deals with the effects of illumination intensity levels on perception conformality and colour saturation in the image of a biological object. Reveals the impact of the optical parameters of an endoscope, the parameters characterizing the biological object and its illumination intensity on the resolution of the optic system of observer's eyes--an endoscope. The biological object illumination intensity range recommended in its visual recording by using rigid endoscopes is defined.
