A modulator (300) according to the embodiment is a modulator provided between a diffraction grating (944) and an image sensor (946), receives a light ray directed to the image sensor (946) from the diffraction grating (944), and changes a travel direction of the light ray emitted toward the image sensor (946) so as to bend a recording direction of a diffraction image for each wavelength of the light ray on a light receiving surface of the image sensor (946).

An analysis and observation device includes: an electromagnetic wave emitter that emits a primary electromagnetic wave; a reflective object lens having a primary mirror provided with a primary reflection surface reflecting a secondary electromagnetic wave and a secondary mirror provided with a secondary reflection surface receiving and further reflecting the secondary electromagnetic wave; first and second detectors that receive the secondary electromagnetic wave and generate an intensity distribution spectrum; and a controller that performs component analysis of a sample based on the intensity distribution spectrum. A transmissive region through which the primary electromagnetic wave is transmitted is provided at a center of the secondary mirror. The transmissive region transmits the primary electromagnetic wave, which has been emitted from the electromagnetic wave emitter and passed through an opening of the primary mirror, thereby emitting the primary electromagnetic wave along an analysis optical axis of the reflective object lens.

A colorimetric apparatus has a shutter unit that can shift between a closed position and an open position. The apparatus body has: a shifting member that can shift between a projection position, at which the shifting member projects in a first direction, and a retraction position, at which the shifting member retracts in a second direction; a first pressing member that presses the shifting member in the first direction; and an operation conversion means that converts the shift operation of the shifting member with respect to the apparatus body to the shift operation of the shutter unit. In a state in which the shifting member is at the projection position, the shutter unit is at the closed position. When the shifting member shifts from the projection position to the retraction position, the shutter unit shifts from the closed position to the open position.
