Abstract:
Provided is a parallel movement mechanism, wherein leaf spring sections (31, 32) are arranged in opposition with each other. A rigid body (33) is arranged at one end of the leaf spring (31) and interlinked with the leaf springs (31, 32), and a rigid body (34) is arranged at the other end of the leaf spring (31) and interlinked with the leaf springs (31, 32). A drive unit (35) arranged upon the face of the leaf spring (31) is comprised of a compact and thin piezoelectric element (35a). The piezoelectric element (35a) is arranged on the surface of the leaf spring (31) at a position to the rigid body (34) side than the center (C) in the longitudinal direction of the leaf spring (31). Since the piezoelectric element (35a) is thus provided on a portion of the surface of the leaf spring (31), the piezoelectric element (35a) is alleviated from becoming a load when the leaf spring (31) is bent and deformed, and a rigid body (33) and a moving mirror (15) can be displaced a great amount by having the leaf spring (31) resonated, even when driving the piezoelectric element (35a) with a low driving voltage.

Abstract:
PROBLEM TO BE SOLVED: To provide a microscope capable of acquiring a time-resolved spectrum. SOLUTION: This microscope 10 is equipped with a microscopic means 12 for collecting light 26 from a measuring area of a sample 22; a multi-element detector 14 having a plurality of elements, for detecting the light collected by the microscopic means 12. In the multi-element detector 14, each element corresponds by 1 to 1 to each fine measuring portion on the measuring area. The microscope is characterized by being equipped with a Fourier transform spectrophotometer 16 as a spectroscopic means, a sampling means 18 for recording intensity data from each element of the multi-element detector 14 simultaneously relative to each element at a timing from the Fourier transform spectrophotometer 16, and a data processing means 20 for acquiring the time-resolved spectrum on the basis of interference light data changing with time acquired by the sampling means 18 relative to each fine measuring portion.
