OPTICAL SYSTEM AND FOCUSING STRUCTURE FOR INFRARED THERMOMETER
First Claim
1. An optical system for an infrared radiation thermometer and its focusing structure, including an eyepiece slide an objective slide component, an objective focusing ring a spectroscope component and an optical outer slide component, wherein:
- an inner cavity of the optical outer slide component is provided with the spectroscope component and the objective slide component,a connecting interface for an infrared focusing light-spot receiving device is arranged outside the optical outer slide component,the back end of the optical outer slide component is provided with the objective focusing ring and the eyepiece slide that are coaxially piled and is further provided with a protective nut cap,an eyepiece can be shifted and focused by stretching the eyepiece slide at the rear end of the optical outer slide,an objective can be shifted and focused by rotating the objective focusing ring, the nut cap at the rear end can be used for locking the measurement image distance of the objective and implementing fully-sealed protection on the whole focusing operation position, andthe optical system directly can be used as an optical probe of the infrared radiation thermometer and can also be used for constructing various other types or forms of infrared radiation thermometers.

Abstract
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.
