<p>An image-capturing unit configured so that the prism can be smoothly interchanged and that the range of measurement can be stabilized. An image-capturing unit (1) is provided with: a prism unit (5) in which a prism (9) is held; a housing (3) provided with a prism insertion section (23), in which the prism unit (5) can be removably inserted, and allowing measurement light to enter the housing (3) from the outside; and two image-capturing elements (7a, 7b) incorporated in the housing (3). The prism insertion section (23) is formed in such a manner that, when the prism unit (5) is inserted therein, the prism insertion section (23) positions the prism unit (5) to a position within the housing (3) together with the prism (9). The image-capturing elements (7a, 7b) are respectively provided at positions which can receive the measurement light dispersed by the prism (9).</p> |
