How do clear and diffuse sample spectra compare on a total transmission accessory?


The graphs at the top show the measured results on the glass filter and opal glass. For a transparent sample such as a glass filter, there is virtually no difference between this spectrum and the linear transmission measurement spectrum. With a translucent sample such as opal glass, on the other hand, as total transmission measurements also detect the diffuse transmitted light, a transmittance approximately 40% higher than the linear transmittance of approximately 0% is produced.

The samples are displayed at bottom center.
