ZnSe

semiconductor

· ZnSe

ZnSe is a II-VI compound semiconductor with a zinc-blende crystal structure, combining zinc and selenium for direct bandgap optoelectronic performance. It is primarily used in infrared optics, laser systems, and high-energy radiation detection where its transparency in the mid-infrared spectrum and radiation hardness are critical. ZnSe is valued in applications requiring windows, lenses, and detectors that operate in wavelength ranges where conventional optical materials (glass, sapphire) are opaque, making it essential for thermal imaging, CO₂ laser optics, and space-based instrumentation despite higher cost than alternatives.

Export Control

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.
