Precision IR Detection For Critical Environments

Opto Diode’s Lead Sulfide (PbS) and Lead Selenide (PbSe) infrared detectors are engineered for precision sensing in mission-critical and environmentally demanding applications. Designed to operate effectively in the mid-infrared (MIR) spectrum from 1 µm to 5 µm, these detectors excel in detecting infrared radiation emitted or absorbed by gases and materials. This capability enables accurate, real-time monitoring of substances such as methane (CH₄), carbon dioxide (CO₂), and various industrial gases.

These detectors are vital for applications like fire and flame detection, greenhouse gas tracking, air quality monitoring, emissions control, and spectroscopy. PbS and PbSe technologies are robust in performance, offering high signal-to-noise ratios (SNR), stable output, and low noise levels. Their reliability under harsh conditions—including noisy environments and wide temperature fluctuations—makes them ideal for use in the oil and gas sector, chemical manufacturing, and mobile sensing systems.

Opto Diode offers both cooled and uncooled detector models, available in rugged TO packages for durability and easy integration. Their standard and customizable solutions allow OEMs and systems integrators to meet specific needs across industries.

By providing accurate IR detection in field-ready, long-life components, Opto Diode supports critical safety systems and helps advance global environmental goals. Their detectors play a central role in ensuring compliance with regulatory standards and improving environmental monitoring capabilities worldwide.
