Has anyone seen retailers selling these types of diodes. I'm making a passive infrared detector as part of a indoor security system. Human peak infrared emission is at around 12 micrometer wavelengths.
Almost all diodes i come across are peaking at around 950nm with upper half bandwidth at 1050 nm which is far from the spectrum i'm seeking.
I would like to do this passively. If i can't find proper passive infrared diodes for 12um i assume i'll have to change my system to an active system with pinging infrared radiation. But that's slightly more complicated.
Anyone run across these types of diodes capable of pointing me in the right direction ?
