LWIR Spectrometer or DLP

Is there a LWIR (8-12um) DLP based spectrometer? If not do you know if the DLP window tranmission and micro-mirror reflectivty would allow this?

    Hi Robert,

    You can find the wavelength transmission numbers in this application note. The micromirror material is very close to bulk aluminum, so it has high reflectivity over a broad wavelength range.

    Unfortunately for your application, no devices are available with windows that support wavelengths past 2.5µm. However, we would be interested in understanding what your potential applications are if you can share them.
