· Hg0.65Cd0.35Te

Hg₀.₆₅Cd₀.₃₅Te is a narrow-bandgap semiconductor alloy within the mercury cadmium telluride (HgCdTe) family, engineered by tuning the cadmium-to-mercury ratio to achieve infrared sensitivity in the mid-wave to long-wave thermal bands. This material is the industry standard for high-performance infrared detection, particularly in thermal imaging and spectroscopy systems where sensitivity, speed, and wavelength selectivity are critical. Engineers select HgCdTe alloys over competing detectors (such as microbolometers or quantum dots) because they offer superior quantum efficiency, fast response times, and mature manufacturing pathways for cooled focal plane arrays used in 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.
