FIELD: computer manipulators.
SUBSTANCE: mutual position in light guide of input lens surface, mirror and output surfaces, and also light guide and objective-lent, is made such, that angle between lighting beams and subject surface is not less than 20°, and also input lens surface is made such, that lighting beam inside light guides is made dissipating, providing close to parallel output lighting beam with high density of light energy.
EFFECT: higher efficiency.
