With the rise of global IR cameras, each wavelength has reached a certain function in different industries, such as short-wave red, which is being used in the automotive field with the rise of ADAS, and medium-infrared, which stabilizes the development of optical components.<\/p>\n\n\n\n

This article introduces the CLAMIR Laser Power Closed Loop Control System<\/strong><\/a>It is one of them, integrating VPD PbSe infrared camera and mid-infrared technology with embedded real-time computing system, and realizes high-quality and sustainable process by continuously controlling the laser work to avoid localized overheating in the process.<\/p>\n\n\n\n

Let's take a look at the CLAMIR system...<\/p>\n\n\n\n

LMD Processing with CLAMIR System<\/strong><\/h2>\n\n\n\n

The continuous control of the laser avoids overheating of the parts during machining and allows a continuous and high quality machining process.<\/p>\n\n\n\n

The use of CLAMIR reduces the ratio of defective parts, material used and energy compared to uncontrolled processes. It can also help optimize processes and increase productivity.<\/p>\n\n\n\n

CLAMIR System Purpose<\/h2>\n\n\n\n

Uncontrolled constant laser power during the LMD process can lead to unstable, non-repeatable processes and poor quality or defective production parts.<\/p>\n\n\n\n

To ensure that the machine produces high-quality parts efficiently, the laser power needs to be controlled continuously and in real time throughout the process.<\/p>\n\n\n\n

\u25cbNeeds a simple system that is fully integrated with the laser optics system.<\/p>\n\n\n\n
