Claim 26:
27. A method of measuring a light absorption of a sample for each wavelength in a light with two different wavelengths, the method comprising:
providing the apparatus of claim 1;
placing the sample to be analyzed in the sample holder, wherein the sample contains or is suspected of containing an analyte that absorbs the light;
shining the light through the sample in the sample holder and measuring the signal IA and IB from the light that passes through the sample from the light that passes through the sample using the color channels of the color camera;
determining the light absorption of the sample for each wavelength using the algorithm and calculating the intensity of Iλ1 and Iλ2 for the sample region and the reference region respectively.
