Product features
1. It features all-weather passive thermal imaging capability, can see through glass, and operates over a wide range of ambient temperatures.
2. With a high frame rate design, the maximum frame rate can reach 125Hz, enabling observation of fast-moving targets.3
3. It employs a self-developed temperature measurement calibration algorithm to achieve precise temperature measurement.
4. It outputs full-frame-lossless 16-bit temperature data and provides client software and an SDK development kit, facilitating secondary development and system integration by users, and enabling personalized temperature analysis of the target under measurement.
Application
The temperature measurement range is 600°C to 2500°C and its temperature measurement accuracy is ±1% or ±1°C.
It can be used for molten metal temperature, laser welding and 3D printing.
Equipment value
1. Real-time Full-field Temperature Monitoring
The infrared thermal imaging camera can simultaneously monitor the laser-affected zone and the surrounding heat diffusion, preventing localized overheating or underheating. Through temperature distribution maps, heat accumulation areas can be intuitively identified, allowing adjustment of laser power or scanning speed.
2. Optimization of Laser Processing Parameters
Different materials have different melting temperatures. The infrared thermal imaging camera helps determine the optimal laser power, scanning pitch, and exposure time. For example, in SLS printing, the thermal camera ensures uniform preheating of the powder bed and reduces thermal stress.
3. Defect Reduction and Improved Molding Accuracy
Through melt pool temperature field monitoring, infrared imaging can clearly display the melt pool shape and temperature distribution, avoiding overheating or lack of fusion defects.
4. Process Development and Quality Control
During the R&D phase, the infrared thermal imaging camera allows comparison of temperature distributions under different parameters, accelerating process optimization. In production, it enables automatic temperature alarms to ensure batch-to-batch consistency.
