Where: 

S

λ

 = the sample intensity at wavelength 

λ

 

D

λ

 = the dark intensity at wavelength 

λ

 

R

λ

 = the reference intensity at wavelength 

λ 

The following figure shows a typical transmission setup. The light source sends light via the input leg of a 
transmission probe into a container. The light interacts with the sample. The output leg of the 
transmission probe carries the information to the spectrometer, which transmits the information to the PC. 

 

Typical Transmission Setup  

Common transmission applications include measuring light through solutions, optical filters, optical 
coatings, and other optical elements (such as lenses and fibers). 

►

 

Procedure 

Perform the following steps to take a transmission measurement using OOIBase32: 

1.  Place OOIBase32 in Scope mode by clicking the 

Scope Mode

 icon on the toolbar or by selecting 

Spectrum | Scope Mode

 from the menu bar.  

2.  Ensure that the entire signal is on scale. The intensity of the reference signal should peak at about 

14,000 counts. If necessary, adjust the integration time until the intensity is approximately 14,000 
counts. 

3.  Place a sample of the solvent into a cuvette and take a reference spectrum. You must take a 

reference spectrum before measuring transmission. 

Note 

Do not put the sample itself in the path when taking a reference spectrum, only the 
solvent.
