Transmittance Measurement With Spectrometers
Transmittance is light incident on a sample that transmits through it. If the sample has low scatter (as with a clean, dilute solution), almost all the light not absorbed or reflected will be transmitted. Transmittance measurements are useful in characterizing translucent or transparent samples.
Use Ocean Optics Spectrometers for Transmittance
Advantages
- Configurability – useable with transmission probes, sample holders
- Simplicity – easy to use and understand
- Versatility – readily converted for absorbance measurements
Applications
- Characterization of glass optical filters and windows
- Measurement of clear solvents
- QC of thin films and coatings in electronics manufacturing
Transmittance Measurement Setup
Here’s an example transmittance system comprising a light source, optical fibers and sampling accessories. For the latter, options include an in-line filter holder and an adjustable collimating lens holder (ideal for extra-thick or larger samples).
