· Cd0.35Hg0.65Te1

Cd₀.₃₅Hg₀.₆₅Te is a cadmium-mercury-telluride (CdHgTe) ternary alloy semiconductor with tunable bandgap energy determined by its cadmium-to-mercury composition ratio. This material is primarily used in infrared detection and thermal imaging applications, where its narrow bandgap enables sensitivity in the mid-wave to long-wave infrared spectrum (3–14 μm), making it the industry standard for high-performance thermal cameras, forward-looking infrared (FLIR) systems, and scientific spectroscopy instruments. CdHgTe is chosen over single-element semiconductors because its adjustable composition allows precise engineering of bandgap energy for specific infrared wavelengths without requiring lattice-matched substrates, though its toxicity and cost limit adoption to high-value military, aerospace, medical imaging, and research applications.

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.
