' Indium Arsenide Antimonide (InAsSb) detector, the P11120-901, provides peak sensitivity in the 5µm infrared spectral band and operates over the entire range from 1.6 µm to 5.8 µm. This high sensitivity is realised via Hamamatsu’
s crystal growth technology. The InAsSb photodiode used in the P11120-901 has a planar structure which ensures a high speed response and high reliability. A typical rise time of 200 ns has been achieved with this detector structure.
Typical applications for this detector include gas analysis; with the detector covering a wide range of molecular absorption wavelengths, in particular for CO2, SOx, CO and NOx. The P11120-901 is also ideally suited for applications in thermometry (radiometry), thermal imaging, remote sensing, FTIR and IR spectrophotometry.
The P11120-901 is not limited to a peak sensitivity of 5 µm, and Hamamatsu are able to shift the peak sensitivity to longer wavelengths by altering the composition ratio of As and Sb in the detector. This means Hamamatsu
can offer a tailor made InAsSb solution for your application.
