· Hg0.4Cd0.6Se

Hg0.4Cd0.6Se is a narrow-bandgap semiconductor alloy belonging to the II-VI compound family, created by partial substitution of mercury and cadmium in cadmium selenide. This material is primarily used in infrared detector systems and thermal imaging applications where sensitivity in the mid- to long-wave infrared spectrum is critical, notably in military, astronomical, and industrial monitoring equipment. The mercury-cadmium-telluride (HgCdTe) family—of which this selenium variant is a related composition—is valued for its tunable bandgap and low-noise performance compared to alternatives like microbolometer arrays or uncooled detectors, though it typically requires cryogenic cooling and careful handling due to mercury toxicity concerns.

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.
