<p>PROBLEM TO BE SOLVED: To obtain a small-sized optical voltage sensor assembly capable of reducing the transmission loss of an optical fiber with easy assembling and improving the reliability. SOLUTION: First and second collimator lenses 5a, 5b are integrally connected with optical fiber connectors 20a, 20b, respectively. A light is directly delivered and received between the first, second optical fibers 7a, 7b mounted at the connectors 20a, 30b and the lenses 5a, 5b. The number of components is reduced, the size is made smaller, the connecting points of an optical path are reduced, the transmission loss of the light is decreased, and hence the measuring accuracy can be enhanced.</p> |
