SPEKTRORADIOMETRY
Badania radiometryczne uwzględniające rozkład spektralny
SPEKTRORADIOMETR
Radiometr mierzy całkowite promieniowanie elektromagnetyczne, podczas gdy spektro-radiometr analizuje rozkład energii w zależności od długości fal, umożliwiając bardziej szczegółowe badania spektralne.
Radiometr:
Radiometr jest urządzeniem służącym do pomiaru całkowitej ilości energii promieniowania elektromagnetycznego, która dociera do niego z danej powierzchni. Radiometry zwykle mierzą całkowite promieniowanie w szerokim zakresie długości fal, niezależnie od konkretnych długości fal lub widma. Radiometry mogą być stosowane w różnych dziedzinach, takich jak astronomia, meteorologia, nauki o środowisku, badania klimatyczne itp.
Uwaga! Nie wszystkie radiometry są wykazane poniżej, tworzymy spektroradiometry/radiometry pod indywidualne zamówienia.

Spektroradiometr:
Spektroradiometr jest bardziej zaawansowanym narzędziem, które oprócz pomiaru całkowitej ilości energii promieniowania, jest również w stanie zbadać rozkład energii promieniowania w zależności od długości fal. Oznacza to, że spektro-radiometr może mierzyć intensywność promieniowania w różnych pasmach widma. Może dostarczyć informacji na temat konkretnych długości fal lub widmowych charakterystyk promieniowania. Spektro-radiometry są szeroko stosowane w badaniach naukowych, takich jak spektroskopia, analiza chemiczna, monitorowanie atmosferyczne itp.
Spektroradiometry są wykorzystywane m.im. do:
- do badania bezpieczeństwa bezpieczeństwa fotobiologicznego
- do pomiarów źródeł światła takich jak diody LED i lasery
- do pomiarów promieniowania słonecznego naturalnego i sztucznego
- do badań procesu utwardzania UV
