Warrendale, PA – [February 13, 2026] – Optotherm, Inc., a designer and manufacturer of infrared imaging components and systems, released the MW640-15, a high-sensitivity MWIR thermal imaging camera designed for front and backside IC failure analysis, lock-in thermography, and microscopic temperature measurement.

Unlike standard MWIR imaging systems, the MW640-15 features NETD <20 mK sensitivity, reducing lock-in thermography test time, while its high spatial resolution enables discrimination of IC features down to 1 μm. The camera includes a 640 x 512 15 µm pitch MCT detector cooled to 80 K using a Stirling engine. Frame rates of 115 Hz (full frame) and 1,550 Hz (windowed) allow analysis of thermal behavior in active IC devices.

Applications include hot spot detection <0.0001 °C, junction temperature measurement, and semiconductor device transient analysis. The MW640-15 can be used standalone or integrated into a turn-key Optotherm Sentris system.

“We developed the MW640-15 for failure analysis engineers who require high spatial resolution and measurement sensitivity, and the ability to perform IC backside analysis,” said Rich Barton, president and technical director at Optotherm, Inc.
