Marktech launches MWIR LEDs in TO-can packages for harsh environments
Marktech Optoelectronics Inc of Latham, NY, USA, a vertically integrated designer and manufacturer of optoelectronics components and assemblies, has released a new series of mid-wave infrared (MWIR) LEDs in rugged, hermetically sealed TO-can packages, engineered to meet the rigorous demands of gas sensing and chemical analysis in industrial environments.
Marktech’s MWIR LEDs are now available with peak wavelengths of 3100nm, 3700nm, 3900nm, 4100nm and 4300nm, enabling precise detection of molecular absorption lines for a wide range of gases and chemical compounds spanning applications including: gas leak detection; process and emissions monitoring; chemical analysis; and environmental & industrial safety.

The robust, hermetic TO-can package protects the sensitive emitter chip from moisture, dust and corrosive agents, ensuring long-term performance and reliability — even in harsh operating environments commonly encountered in chemical plants, oil & gas refineries, and power generation facilities.
“Reliable optical components are essential when safety and accuracy are critical,” says global business development manager Gary Kardys. “Our hermetically packaged MWIR LEDs are designed with industrial-grade resilience to deliver consistent performance in mission-critical sensing applications.”
