The ratio of the distance to the spot of the laser pyrometer, the optical system of the laser pyrometer collects energy from the circular measuring spot and focuses it on the detector, and the optical resolution is defined as the ratio of the distance from the infrared pyrometer to the object to the size of the spot being measured (D:S). The larger the ratio, the better the resolution of the laser pyrometer, and the smaller the measured spot size. Laser aiming, only to aid aiming at the measuring point. The latest improvement in infrared optics is the addition of a near-focus feature that provides accurate measurement of small target areas and prevents the effects of background temperature.

The application of infrared in temperature measurement, especially the near-infrared in high-temperature temperature measurement, has unparalleled advantages such as non-contact, fast response, long service life, etc. It is widely used in welding, medium and high frequency induction heating, heat treatment, Metallurgy, casting, hot forging, leather, rubber, electric power, chemical industry, glass, ceramic production and other industries, due to the characteristics of industrial production equipment, most of them are limited to temperature measurement, which is more realistic. Experience and market needs, while satisfying the temperature measurement, it pays more attention to automatic temperature control, continuously improves the practical performance of the product, maximizes the convenience for customers to use with their existing equipment, and can, if the existing hardware allows, timely Modify the relevant software parameters to achieve the best results.
