What Is the Optris PI Series of Thermal Imagers

The Optris PI series offers high‑performance, real‑time thermal imaging in ultra‑compact designs weighing under 320 grams. With frame rates up to 128 Hz, these cameras capture fast‑moving processes with exceptional clarity for both snapshots and video recording.

Key advantages include:

• Outstanding thermal sensitivity to detect even the smallest temperature variations
• Variable optics and cable options for flexible installation
• Some models as small as 46 mm x 56 mm x 90 mm, making them among the smallest infrared cameras in the world

These features make the PI series ideal for detailed thermal analysis, rapid process monitoring, and precise documentation of thermal behaviour.

The Optris PI Precision Line includes a diverse range of models to suit every industrial requirement—from the versatile PI 400i/450i to the high‑resolution PI 640i with 640 × 480 pixels, as well as specialised cameras for metals, glass, and micro‑scale applications.

This comprehensive thermography range ensures you get the perfect imaging solution for your specific needs.

What Is a Thermal Imaging Camera

A thermal imaging camera creates a digital thermal image by mapping the temperature of objects within its field of view. Every surface emits infrared energy, and the camera converts this energy into a detailed temperature image.
