· Hg0.8Cd0.2Se

Hg0.8Cd0.2Se is a mercury-cadmium-selenide ternary alloy semiconductor belonging to the II-VI compound family, with composition tuned toward the infrared region of the electromagnetic spectrum. This material is primarily used in infrared photodetectors and imaging systems operating in the 8–14 μm wavelength band (thermal infrared), where its narrow bandgap and high carrier mobility provide sensitivity advantages over broader-gap alternatives. Engineers select this alloy when designing cooled thermal cameras, forward-looking infrared (FLIR) systems, and spectroscopic instruments requiring room-temperature or cryogenic operation; its use in defense, medical thermal imaging, and scientific research reflects a balance between performance and the material's inherent toxicity constraints.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
