ATLAS Hermetic SMD Packaged InGaAs Photodiodes

Marktech Optoelectronics has unveiled hermetic surface-mount device (SMD) packaged InGaAs PIN photodiodes with cutoff wavelengths of 1.7 µm and 2.6 µm. These detectors outperform other InGaAs sensors in the extended short-wave infrared (SWIR) range and boast exceptional sensitivity, linearity, quantum efficiency, and low dark current. Encased in ATLAS packaging, these photodiodes are well-protected against water vapor, oxygen, and gaseous contaminants, ensuring reliable functionality even in harsh conditions. This makes them ideal for various applications including aerospace, medical, defense, wearables, and industrial sectors. Additionally, this innovative product won the 2023 Best of Sensors award in the aerospace category at Sensors Converge.

Marktech's InGaAs detectors come in different active area sizes, offering a choice between higher gain or faster response speed. The detectors' ability to sense light in the SWIR range has opened up new possibilities in medical diagnostics, food sorting, and chemical analysis, with deeper tissue penetration for medical applications. Moreover, the ATLAS surface-mount package features a compact footprint and low profile, making it suitable for miniaturized, lightweight, and power-efficient designs in wearables and aerospace projects.

Marktech's InGaAs photodiodes can be combined with silicon photodiodes for a broad detection range, and when paired with appropriate SWIR LED emitters, they exhibit obscured environment sensing capabilities, enabling detection through smoke, dust, water vapor, and select plastics. This capability finds applications in mining, automotive, military, marine, process plant, and security sectors. With their commitment to high-quality and reliable components, Marktech has become a trusted partner across industries. In addition to InGaAs detectors, the company offers a range of silicon photodiodes, including customized designs to meet various detection needs from ultraviolet to extended SWIR.
