· Cd0.23Hg0.77Te1

Cd0.23Hg0.77Te is a cadmium-mercury-telluride ternary compound semiconductor, part of the II-VI semiconductor family widely studied for infrared detection and optoelectronic applications. This material is primarily used in long-wavelength infrared (LWIR) detectors, thermal imaging systems, and space-based sensing instruments where sensitivity in the 8–14 μm range is critical. The cadmium-mercury-telluride system is valued for its tunable bandgap across infrared wavelengths and high quantum efficiency, making it the material of choice for military, aerospace, and scientific imaging where alternatives like uncooled microbolometers or indium antimonide offer inferior performance at longer wavelengths.

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.
