<p>An optical system and a focusing structure for an infrared thermometer are provided. The optical system includes a focusing ocular barrel (100) and an objective focusing ring (300), provided at the rear end of an optical probe. By controlling the shift of the ocular (101) and the objective (201), the best visual collimation definition and the highest optical focus resolution of the system can be achieved without reducing the measurement precision. The rear end of the probe includes a cap (507), which can be used for locking the detective image distance of the objective (201) and sealing and protecting the portion of the focusing operation.</p> |
