Transmittance Measurements

 

Three techniques are used to measure the transmittance of samples: “regular” 
transmittance, “total” transmittance and “diffuse” transmittance.   

 

Regular Transmittance 

 

When working with samples that are completely transparent (such as dyes in solution or 
transparent plastics) you are measuring “regular” transmittance. These samples need to be 
positioned close to the lens opening at the back of the transmission compartment using 
either the cuvette holder or solid sample holder as appropriate:
