Since the displacement of the profilometer
sensor cannot exceed 10 mm, we took radial measurements starting from an uneroded part of the surface in the centre of the sample.
The molded parts with 100-[micro]m thick microchannels were examined after injection molding with the optical profilometer
to determine the replication accuracy of microfeatures.
It comprises two independent profilometer
sensors: one optical and one conventional with a contact stylus.
Figure 11 shows the typical surface roughness profile obtained by a non-contact type surface profilometer
(Bruker 3D Noncontact profiler).
Although the castings appeared smoother, the refractory coatings increased the surface roughness as measured by the profilometer
Surface roughness levels were measured with the help of surface profilometer

Another measuring tool used in our study was IFM, the non touch profilometry, which is a laser profilometer
used for the measurement of Sa and Ra.
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.
The instrument can also be used as a micro scratch tester, micro wear tester, fatigue tester and high-resolution profilometer
ASTM International's proposed WK49335, Test Method for Concrete Micro Surface Texture, describes the use of a contact stylus instrument, or profilometer
, and reliable data indexes to measure and quantify a slab or structure's smoothness/roughness value.
The dependent variables were the percentage of surface hardness loss (%SHL), as quantitatively evaluated by differences in the mean values of superficial microhardness after treatment, and dentinal wear and roughness, as assessed by the contact profilometer
Hommel Tester T1000 (Jenoptik, Schwenningen, Germany).
