· JVASP-108770· InGaSb2

InGaSb₂ is an indium gallium antimonide compound semiconductor ceramic, belonging to the III-V semiconductor family used in optoelectronic and infrared device applications. This material is primarily employed in infrared detectors, thermal imaging systems, and mid-wave to long-wave infrared sensors where its narrow bandgap enables detection of longer wavelengths than conventional semiconductors. InGaSb-based devices are valued in defense, aerospace, and industrial thermal sensing applications because the material's composition allows tuning of optical response across the infrared spectrum, making it a preferred alternative to mercury-based detectors and other infrared materials in critical sensing systems.

Regulatory Screening

Environmental

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.
