Temperature control directly determines the quality and service life of laser fiber. During the use of the fiber, it absorbs some of the laser energy, causing the temperature to rise. If the temperature is too high, the fiber will age faster, leading to a vicious cycle of high temperature->accelerated aging->higher temperature, which reduces the reliability and service life of the laser.
Using an ir thermography to detect the temperature of the entire fiber, especially the fusion point of the fiber during use, can promptly discover temperature abnormalities and take protective measures to avoid fiber damage.
Device aging can cause system failures in the fiber laser, and after aging, the equipment will have abnormal high temperature. Using an ir thermography to detect it will obtain the highest temperature image and data.
Using an ir thermography to detect electronic components can measure the temperature in detail.
Using an ir thermography to conduct overall thermal imaging tests on the gain fiber section can quickly locate the main heat-generating areas.
For the detailed test of the fiber, the ir thermography can observe the specific temperature of each fiber, which is more conducive to the analysis of detail temperature problems of the gain fiber.
For the fusion point of the collimator and gain fiber and the cladding stripping point, which are commonly known as low glue and high glue points, the critical points in the fiber fusion process have large temperature gradients at high power, and low-resolution equipment cannot test the true temperature.
The principle of using an ir thermography is to convert the invisible infrared energy emitted by an object into a visible thermal image and measure the target temperature through an infrared emitter, which is then displayed on the screen. The birth of this simple, fast, accurate, and safe high-end detection instrument is undoubtedly a blessing for many detection and maintenance industries. However, if the operation is not standardized during use, it can easily lead to inaccurate data and even shorten the service life of ir thermographys.
When using an ir thermography, if the temperature of the background around the target measured is too cold or too hot, it will affect the accuracy of the target temperature measurement. Generally, the application of the ir thermography can adjust the curve of the thermal image after it is stored, but it cannot change the focal length after the image is stored, so it is impossible to eliminate other thermal reflections. Therefore, at this time, we need to adjust the focus or measurement orientation to reduce or eliminate these influences. The ir thermography is equipped with a unique laser autofocus system, which can visually indicate the target position and is suitable for multiple and multi-directional autofocus operations.
