In order to have a more accurate determination of the cure time, the surface quality of molded parts was evaluated using the optical profilometer
. Increasing the mold opening time, the measured surface roughness decreased in all mold temperatures.
In addition, Atomic Force Microscopy or Scanning Electron Microscopy analyzes of samples may be performed to support surface roughness measurements with profilometer
and Dapino, M., "Experiments on Ultrasonic Lubrication Using a Piezoelectrically-Assisted Tribometer and Optical Profilometer

Normally was not very significant indeed the profilometer
head is forced to run between two tracks represented by two adjacent slices.
The validity of the proposed method was verified compared to stylus profilometer
Although the castings appeared smoother, the refractory coatings increased the surface roughness as measured by the profilometer
. The alcohol-based alumina coating exhibited the best performance while the alcohol based zircon coating resulted in the highest roughness.
The surface profilometer
(Figure 5), an instrument which measures a surface's profile in order to quantify its roughness, helped evaluate and quantify the surface roughness of the restorations.
Surface roughness levels were measured with the help of surface profilometer
. Surface wettability was measured with the help of contact angle measurement using contact angle measurement setup, and surface configuration was determined with the help of scanning electron microscopy.
measurements and sheet resistance where done for 10 samples of each layer material.

These studies employed equipment like SEM, profilometer
, focus variation microscopy, VHN (with Vickers and Knoop indents) detection and energy-dispersive X-ray spectrophotometry (EDS).
In addition to the two ART devices on site, the lab will include a profilometer
for mapping surface roughness, a spray booth that can handle two full sheets of drywall at one time, and a viewing/ evaluation area with variable integrated lighting (incandescent, CFL, LED) that accommodates a full sheet of drywall.
