High-Performance Detectors For Infared Sensing Systems

Designed and manufactured in the United States under ITAR-compliant and ISO 9001:2015-certified processes, these detectors provide consistent responsivity and low noise across demanding industrial and environmental conditions—making them ideal for continuous monitoring, process control, and analytical instrumentation.

Engineers developing infrared platforms for flame detection, gas concentration analysis, thermal imaging, or scientific measurement benefit from Opto Diode’s ability to tailor detector configurations to precise application requirements. PbS detectors offer excellent sensitivity from 1–3 µm, supporting combustion monitoring and spectroscopy, while PbSe devices extend broadband response up to 5 µm for gas-sensing and temperature-measurement applications. Both materials are available in uncooled, single-stage, and two-stage thermoelectrically cooled designs that reduce dark current and drift, enabling stable, high-detectivity operation even in harsh or highly dynamic environments.

Each detector is fully characterized for detectivity (D*), noise-equivalent power (NEP), and spectral uniformity to ensure accurate and repeatable measurements. With fast response times, rugged packaging, and multiple active area options, Opto Diode’s detectors integrate seamlessly into new or existing IR sensing systems. Their performance supports critical applications such as environmental gas monitoring, industrial process spectroscopy, flame and fire detection, targeting, and research-grade instrumentation—delivering dependable infrared sensing across the 1–5 µm spectrum.
