Optris Pi 640i Thermal Microscope for Precision Infrared Measurement

The microscope lenses for the PI 640i online thermal camera are made for precise thermal inspection of electronic boards, microelectronic assemblies, and chip-level components. They achieve spatial resolutions as low as 28 µm. When paired with the PI 640i online thermal camera, this thermal microscope set is perfect for laboratory analysis, product development, validation, and failure analysis in electronics and semiconductor fields. The system allows hands-free operation for testing, probing, and measuring temperature at the same time. This makes it a strong choice for detailed thermal investigations. The working distance is set between 80 and 100 mm, which guarantees stable focusing and consistent measurement conditions. The VGA detector resolution is 640 × 480 pixels, and the pixel pitch is 17 µm, optimized for long-wave infrared radiation (8–14 µm). This ensures high image quality, low thermal noise, and a temperature resolution of up to 80 mK. With a minimal Measurement Field of View (MFOV) of just 3 × 3 pixels, the PI 640i thermal microscope can accurately measure temperature on very small targets. It avoids typical errors caused by thermal bridging effects that can occur with contact sensors. Frame rates of up to 125 Hz allow for the analysis of quick thermal changes, such as those from pulsed laser diodes or fast-switching electronic components. The package comes with German-designed, interchangeable microscope optics, a precision mounting stand, and the optris PIX Connect software that requires no license. This software fully supports SDKs for Windows and Linux. Additional accessories, including interchangeable lenses, industrial process interfaces, and longer USB cables, enable flexible integration into automated test setups. As an online thermal camera system, the PI 640i thermal microscope gives engineers reliable, non-contact temperature data, boosts measurement confidence, and offers valuable thermal insights for demanding micro-scale applications.
