The LWIR Thermal Camera represents the pinnacle of miniaturized infrared technology. Designed for versatility, it supports a wide variety of serial communication and video output interfaces, making it the perfect core for UAVs, enhanced night vision goggles (ENVG), and handheld devices.
This module excels in both observation and measurement. The standard version provides high-frame-rate (50Hz) thermal video for fluid situational awareness, while the radiometric version (25Hz) is tailored for industrial and electric power temperature monitoring. With advanced built-in image processing-including Digital Detail Enhancement (DDE) and 3D Noise Reduction (DNR)-the L640 delivers stable, high-contrast imagery through smoke, dust, and total darkness.
