A Hermetic Photodiode is a photodetector packaged in a sealed enclosure designed to limit moisture and contaminant ingress over time. Hermetic sealing can improve long-term stability and reliability in environments with humidity, temperature cycling, or harsh handling. Hermetic packages may use metal or ceramic housings with glass windows and controlled internal atmospheres. These photodiodes are used in aerospace, defense, and industrial instrumentation. GPD Optoelectronics manufactures photodiodes available in hermetic package options.
Learn where near-infrared photodiodes fly in aerospace systems, which specs deserve a hard look, and why in-house fabrication, military-standard testing, and lot-level traceability matter for missions that must work the first time.
