· Hg0.63Cd0.37Te

Hg0.63Cd0.37Te is a narrow-bandgap semiconductor alloy within the mercury cadmium telluride (HgCdTe) family, engineered for infrared detection and imaging applications. This material is the industry standard for thermal imaging, night vision, and long-wavelength infrared (LWIR) sensing systems, prized for its tunable bandgap that allows precise control of detection wavelengths by varying the mercury-cadmium ratio. Engineers select HgCdTe over competing infrared detector materials (such as indium antimonide or bolometers) for applications requiring high sensitivity, fast response times, and operation across specific infrared bands critical to defense, 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.
