Optris PI 640i Online Infrared Camera | 640×480, NETD 40 mK, 32 Hz (125 Hz subframe), -20–900 ℃ (1500 ℃ optional), IP67

Optris PI 640i Online Infrared Camera: 640×480 VGA

Overview

The PI 640i (LT, 8–14 µm) is an online infrared camera in the Optris Precision Line. It connects to a PC via USB and works with the free PIX Connect software for real-time display, analysis and recording. With a 640×480 detector and 17 µm pixel pitch, the target only needs to cover 3×3 pixels. The rear process interface outputs measured values and accepts trigger and sync signals, and SDKs are available for Windows and Linux. An Optris infrared microscope optics kit for small-target measurement is also available on request.
