5. Instrument setting for reflectance measurement
Reflectance is calculated from the spectrum of the light source and the spectrum
reflected on the object to be measured. Since it is necessary to irradiate stronger light to
detect the reflected spectrum, a separate high power light source is required. Similar to
the measurement of absorbance, to measure the reflectance, first measure the spectrum
of the light source and then measure the light reflected on the object to be measured.
When the measurement is completed, the program automatically calculates the
reflectance spectrum.
Application example using relectance probe
Color analysis of objects can be performed by measuring the reflected light spectrum.
The optical fiber of the light source and the optical fiber for measurement are
incorporated into the reflected light measurement probe, and the reflection spectrum
measurement can be performed simply by fixing with a dedicated probe holder.
