Description

Technical Field

[0001] This utility model relates to the field of spectral analysis technology, and in particular to a stage device for a spectral analyzer. Background Technology

[0002] Currently, the stage design of spectrometer products is limited and lacks motion capabilities. The homogenizing device in a spectrometer must actively approach the stage for sample detection. Furthermore, the assembly and adjustment process of a spectrometer requires additional specialized tooling for focusing and alignment. While traditional spectrometers use a gray card to assist in camera reflectivity calibration to improve detection accuracy, this process is cumbersome as the gray card must be placed beforehand for image capture.

[0003] In existing spectrometers, the stage is a fixed structure with a petri dish tray on the platform. During operation, a motor drives a homogenizing device located above the petri dish to move downwards, close to the dish, and sample the sample for analysis. In this configuration, the stage remains stationary while the homogenizing device moves to the detection position driven by the motor. The homogenizing device is a relatively large and heavy sphere, resulting in significant power consumption for the motor during long-term operation. Furthermore, the stage lacks a target for real-time monitoring of the light source brightness within the homogenizing device, thus failing to address the impact of light source variations on the accuracy of spectral measurements.

[0004] Therefore, how to provide an adjustable stage that can improve the accuracy of spectral measurements is a technical problem that needs to be solved by those skilled in the art. Utility Model Content
