Integrating cavity absorption meter

NettetThe integrating cavity absorption meter ~ICAM! permits the measurement of very small optical ab-sorption coefficients ~0.001 m21!, virtually indepen-dent of scattering effects in the sample. Briefly, the sample is isotropically illuminated in a cavity whose walls have a very high diffuse reflectivity, typically.99%. Nettet1. sep. 1990 · Accurate measurement of the optical absorption coefficient for both pure and natural waters has been complicated by the effects of scattering particulates. A new absorption meter which eliminates the systematic effects of scattering has been developed. This device, hereafter referred to as the Integrating Cavity Absorption …
