Abstract
An electro-optic probe is provided which is able to prevent unnecessary reflected light from optical components in the electro-optic probe from entering photodiodes. The optical components which constitutes an isolator 13 are disposed inclining from an optical path of a parallel light emitted from a collimating lens 8, such that the unnecessary reflected light beams from these optical component surfaces are not incident to the photodiodes 10 and 11. The inclination angle of these optical components are set within a range from an angle formed by an optical path from said optical component to a light receiving element in said photodiode, and the diameter of said light receiving element to an angle allowable for the optical component to maintain the transmittance thereof.
