MIRROR HOLDING BODY AND OPTICAL AXIS CORRECTION DEVICE USING THE BODY

摘要

PROBLEM TO BE SOLVED: To provide a high response optical axis correction device capable of precisely adjusting an optical axis, and to provide an optical space transmission device suitable for long distance optical space transmission using the optical axis correction device. SOLUTION: A two axes spring 1 setting a mirror is provided with a first circular part 5, a second circular part 6 which is on the outer side of the first circular part 5 and is set in a concentric form, and a third circular part 7 which is on the outer side of the second circular part 6 and which is set in the concentric form. The first circular part 5 and the second circular part 6 are connected by a pair of X-axis bridges 3 which face each other by sandwiching a concentric center and which can be twisted/rotated or Y-axis bridges 4 similar to the second circular part 6 and the third circular part 7. The X-axis bridges 3 and the Y-axis bridges 4 are installed by providing prescribed angles with the concentric center as a reference and are installed by providing the same angles against the rolling direction of a rolled member forming the two axes spring 1 with the concentric center as the reference.
