Since light cannot penetrate opaque (solid) samples, it is reflected on the surface of the samples.

With relative specular reflectance measurement, the reflectance is calculated from the strength ratio after comparing the light reflected from the reference sample with the light reflected from the measurement sample.
-
With absolute specular reflectance measurement, as shown in the figure, a reference sample is not used, the sample-free state (air) is set at 100%, and the reflection of the sample is simply applied to the 100% setting when measuring the sample.

The transmittance of thin samples such as film with little scattering can be measured by combining the film holder with the standard sample compartment.
-
This large-sample compartment enables transmission and reflection measurements of various-shaped samples.
