North American research company and global supplier of thin-film optical coating products Grauling Research Inc. has announced IR-ISE (Infrared – Improved Sensor Efficiency), an improved photoconductive infrared sensor coating that enhances performance improves efficiency of infrared sensors.
The novel thin-film coating was developed for use with lead sulfide (PbS) and lead selenide (PbSe) sensors. Due to the high index of refraction in current lead-salt sensor technology, around 40% of the incident infrared radiation in today’s common sensor materials is lost due to surface reflection, explained a Grauling Research press release. IR-ISE thin-film PbS and PbSe coating designs can reportedly reduce the surface reflection of incident radiation by utilizing environmentally-rugged, single or multi-layered thin-film coatings.
In applications where glass encapsulation is no longer needed, the new IR-ISE reduces the size and weight of the photodetector and lessens the amount of time, materials, and labor costs needed for assembly, according to Grauling Research, which continues to conduct research on other photoconductive and photovoltaic IR materials.
