This automatic analysis apparatus is provided with: an analysis port comprising a reaction container holding part that holds a reaction container storing the liquid mixture of a sample and a reagent, a light source that emits light to the liquid mixture stored in the reaction container held by the reaction container holding part, and a detector that detects light generated when the light from the light source is emitted to the liquid mixture; and a control unit that controls the analysis port, and analyzes the sample on the basis of information about the detected light. The automatic analysis apparatus is characterized in that: the surface of an inner wall of the reaction container holding part is configured to reflect at least a portion of the light emitted from the light source; and the control unit executes control so as to emit the light from the light source in a state where the reaction container is not held by the reaction container holding part, to detect the light reflected on the surface of the inner wall of the reaction container holding part by the detector, and to not use the analysis port for analysis when the result of the detection shows that the detected light is less than a first value determined in advance.

The present invention is a multi-spectral digital autocollimator system featuring a diverse range of capabilities. It comprises a multi-spectral light source spanning from deep UV to Far-IR (8-12 microns), a collimating mirror, a unique optical beam splitting lens, and an imaging device designed to detect the light deviation caused by the multi-spectral light source. The system projects the light through a specially designed cross target, generating visible light, and this cross target can be heated or cooled to create a high-quality black body cross. The resulting light is then reflected back from an examined reflective object and captured by the imaging device. An appropriate thermal camera is strategically positioned after the optical beam splitting lens to analyze the thermal properties of the black body cross. The primary objective of this invention is to offer a precise and multi-spectral digital autocollimator capable of facilitating optical alignment with different spectral devices.
