[0002] Existing fully automatic biochemical analyzers use the principle of photoelectric colorimetry to measure specific chemical components in body fluids. The optical analysis device of a fully automatic biochemical analyzer generally includes a light source and a photoelectric detection unit. The light source is used to illuminate the sample area, which absorbs light of a specific wavelength. The photoelectric detection unit is used to detect the light passing through the sample. The photoelectric detection unit generally includes an incident lens, a grating, and a photoelectric component arranged in sequence along the optical path. Fluorescence passes through the incident lens and is incident on the grating, which splits the fluorescence and then transmits it to the photoelectric component, which performs photoelectric conversion. To ensure that the photoelectric component receives the desired wavelength of light after the grating splits the fluorescence, the user needs to adjust the wavelength and intensity of the light incident on the photoelectric component by adjusting the angle of the grating. However, the current sampling method for adjusting the grating angle is to push the grating base with a bolt, which has a large adjustment error and is difficult to accurately adjust the grating to the desired angle.
