Plastic laser welding has been widely used for various spare parts, and the transmittance of plastic is an important indicator of welding process quality. We have launched a transmittance detector specifically designed to detect the near-infrared transmittance characteristics of plastic materials for this type of plastic material. It performs full screen scanning of the transmittance of welded plastic parts and detects multiple points simultaneously. You can freely define the detection area and set the transmittance range according to your needs, automatically extract the transmittance and welding quality of the detection area, and automatically judge whether it is OK or NG. This product is suitable for multi-point testing of samples, avoiding missed tests, easy testing operation, extremely fast testing speed, and can complete measurements within one second.
