Precision Entry-Level MWIR Thermography for Versatile Measurement Tasks

The InfraTec ImageIR 4300 is a high-performance, entry-level MWIR thermographic camera designed to handle a wide range of industrial and scientific measurement challenges. 

At its core is a cooled MCT focal plane array detector with a 320 × 256 pixel format and 30 µm pixel pitch, delivering excellent thermal sensitivity (better than 0.02 K) and reliable radiometric data across demanding environments. 

The ImageIR 4300 supports snapshot imaging with rapid readout and delivers thermal images with well‑defined detail that reveal subtle temperature differences that other systems may miss.

 

Key Features:

  • Large 320 x 256 pixel detector
  • Up to 75 Hz full frame rate
  • High thermal resolution better than 20 mK
  • Pixel pitch of 30 µm
  • Separate filter wheel and aperture wheel design for high flexibility
  • Short integration times
