Abstract
It have been done comparison Monokromator 270M Rapid Scanning Imaging
Spectrograph / monochromator use the UV-VISIBLE Spectrofotometer SHIMADZU 1601PC by
comparing result of both transmitant percentage appliance. Measurement of this percentage of
transmittance (T%) Monokromator 270M got by measuring initial intensity( I0 ) and materials
intensity test the ( I). From both the intensity value countable the level of the percentage of
transmitansi(T%) using the formulation T = I / I0 x 100 %. Both comparison result of appliance
presented in the form of graph of comparison T%. From comparison result got an accurate result
for the wavelength of visible light (381-740nm). Because graph formed is continu. While for the
determination of Coefficient of attenuation of materials (m) can be searched with the deferential of
Lambert-Beer equation which
x
IILn )/( 0
-= m and got the value equal to ± 38 / (1/mm) for
the sampel of spectrum 20% and equal to ± 10 / (1/mm) for the sampel of solar quard 60%.
Keyword :Initial intensity(I0 ), Material intensity(I), Transmitance percentage ( T%),
Lambert-Beer equation, Coefficient of attenuation(m).
