Precise High Resolution VGA IR camera, Measuring –20 °C to 1500 °C

The Optris PI 640i is a high-accuracy, high-performance thermal imager with VGA resolution. It captures 640 × 480 radiometric images and radiometric video. Its 17 µm pixel pitch in the LWIR band combines high sensitivity with low noise, down to 25 mK. As a result, the online thermal camera measures tiny targets that only need to span 3 × 3 pixels. The stationary thermal imaging camera measures temperatures from –20 °C to 1500 °C in the 8–14 µm wavelength range, making it suitable for stationary monitoring in various industrial applications.
The PI 640i LT thermal camera now also comes with a 120° ultra-wide-angle lens—the first of its kind in industrial thermography. Consequently, it delivers a 120° × 100° field of view for wide-area process monitoring. In addition, interchangeable optics, including a 15° × 11° telephoto, adapt the thermal camera to diverse tasks. The thermal camera hardware uses AR-coated LWIR optics in a rugged metal housing with internal temperature compensation for radiometric stability.
Moreover, with 32 Hz full-frame output and a 125 Hz high-speed subframe mode, the PI 640i thermal camera resolves fast thermal transients and short-lived hotspots with minimal motion blur for precise timing in rapid processes. Per-pixel radiometry runs at full frame rate.
A rear process interface (analog/digital via the supplied cable) links directly to process controls or host controllers. It outputs measured values and handles triggers and synchronization at the hardware level. Additionally, an SDK and drivers for Windows and Linux environments support application integration, including triggering, synchronization, and data acquisition.
