What was the challenge or problem to solve?
In order to know if the properties achieved were the desired ones, and thus to be able to adjust the paint formulations, it was necessary to be able to characterize its reflectance properties in the near infrared zone.
How was it addressed or what was the solution?
To do this, a spectrophotomer equipped with a diffuse reflectance sphere was used, which enables direct and diffuse spectra to be obtained.
The equipment analysis conditions were selected in order to work according to the client’s standard, and spectra were obtained for the different samples and paintings.
- Characterize the diffuse reflectance of paintings in the near infrared zone
- Study of reflectance using a spectrophotometer equipped with a diffuse reflectance sphere
