<p>PROBLEM TO BE SOLVED: To suppress the deviation of an optical path under a vibration environment by mechanically canceling a relative dislocation between an optical path fixed with a simple mechanism and a varying optical path. SOLUTION: In a device of laser beam transmission with mirrors, the fixing position of a mirror 4 is located at the vertex of a rhombus, supporting points are located at equal distances from the mirror on both optical axes so that an incident light axis and a reflected light axis make two adjacent sides of the rhombus, and the supporting points are connected with another supporting point which freely moves side by side on the diagonal including the mirror. It is preferable that another mirror is provided on either the incident light axis or the reflected light axis and the mirror swivels on the axis and polarizes the light.</p> |
