Designed to operate in wavelengths ranging from 2 to 14µm, the sensors can be used to detect gases such as carbon dioxide and ethanol vapours.
The CCS11x family is said to incorporate a patented plasmonic structure, in which a layer of metallic dots with a defined geometry creates a resonant effect, increasing the sensors’ optical emissions.
Each part uses CCS’ patented microhotplate design to deliver high optical emissions with a stable, low drift output. The plasmonic structure and the micro-hotplate are fabricated using a standard CMOS process.
The CCS11x family is said to have an inherently low thermal mass, which allows for rapid heating to high temperatures (up to 600°C), allowing pulse mode operation at high frequencies and low power consumption. Alongside a stable output with low drift, the parts also offer: switching at up to 38Hz with a 50% modulation depth; high IR radiation output, with an emissivity of 0.8 at 4.26µm; pulse mode operation; and a reliable design
Jess Brown, CCS’ sales and marketing director, said: “These devices will enable our customers to have lower power, smaller optical gas sensing products which can be used to monitor specific gases and to detect greenhouse gases and refrigerants for demand control ventilation, building monitoring, automotive cabin control, and industrial safety and security applications.”
The CCS112A, CCS113A and CCS114A are now sampling now in TO46 and TO39 packages.
