We own an Agema 900 thermographic system with microscope lens which
we often use for thermal characterization of microsystems.
Experience has shown that tabulated values of material emissivities
are hardly usable in practice. As you may find in literature, various
kinds of emissivity are defined and what you need uses to be a
mixture of several values. It is therefore better to calibrate your
system well and calculate the emittance. If you like, we can try to
support you with our system.
Yours sincerely, Kai Hiltmann
