· Hg0.796Cd0.204Te

Hg₀.₇₉₆Cd₀.₂₀₄Te is a mercury-cadmium-telluride (MCT) alloy semiconductor, a narrow-bandgap III-VI compound engineered for infrared detection applications. This specific composition places it in the mid-wavelength infrared (MWIR) detection range, making it the dominant material choice for thermal imaging, night vision systems, and remote sensing where sensitivity in the 3–5 μm wavelength region is critical. Engineers select MCT alloys over alternatives like microbolometers or uncooled detectors when cooled, high-sensitivity infrared focal plane arrays are required, offering superior detectivity and imaging performance in military, aerospace, and scientific instrumentation.

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.
