When electromagnetic radiation in the UV/Visible wavelength range interacts with a sample, four results are possible: the radiation is
absorbed, transmitted, reflected or scattered. Typically UV/Vis spectrometers are equipped to measure the transmittance or absorbance of a transparent homogenous solution. However, when equipped with the proper accessories, UV/Vis instruments can
measure the reflected and scattered
energy from a sample. An integrating sphere, when used in combination with the Lambda 35 spectrometer, is a valuable tool for collecting and measuring reflectance. The high-energy optical system of the Lambda 35 ensures ow noise measurements
and dependable results. The Lambda 35 is controlled from a Windows® based computer using UV WinLab™ software.
