Pyroelectric Detectors Series PEM HP
with broadband absorption coating for higher average power


In opposition to our other detectors of series PEM these detectors are allowing higher avarage power densities.

As absorption coating we are using here also our proven black coating with an very high and flat absorption over a wide wavelength range.
