· Cd0.37Hg0.63Te1

Cd₀.₃₇Hg₀.₆₃Te is a cadmium-mercury-telluride (CMT) ternary semiconductor alloy, a member of the II-VI compound semiconductor family widely used for infrared detection and imaging. This specific composition falls within the mid-wave infrared (MWIR) detection range and is valued for thermal imaging, military surveillance, and scientific instrumentation where sensitivity in the 3–5 µm wavelength region is critical. CMT alloys like this are preferred over alternatives such as lead-based or silicon-based detectors because they offer superior performance at longer wavelengths and can be engineered for room-temperature or cryogenic operation depending on application requirements.

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.
