Figure 5
The correlation between sample thickness, concentration and extinction coefficient and their effect on light transmission. The figure shows the 50%, 75% and 90% transmission thresholds of light through samples of varying thickness (10 µm to 1 mm, color-coded). These transmission thresholds correspond to 50%, 25% and 10% attenuation, respectively. The extinction coefficient (x axis) and sample concentration (y axis) are varied. Insets (a)–(c) show different areas in more detail for the 75% transmission plot, where (a) is high ɛ and low concentration, (b) is low ɛ and high concentration and (c) is low ɛ and low concentration. |
