Control of reflective surfaces
Reflective surfaces: QualiSENSOR® 100 and 200
On specular surfaces such as part of an automobile body, a silicon wafer or even a sapphire watch glass, the QualiSENSOR® is best able to highlight, detect and evaluate defects and surface characteristics.
The QualiSENSOR® system operating in reflection is available in two versions: 100 and 200.

Each user may have different applications and therefore different needs, we also design tailor-made systems.
The features:
01 Surface characterization
Our full-field measurement system is capable of evaluating minute deviations from a surface (compared to a perfect surface). The high resolution of our sensors associated with our signal processing technologies allows us to be sensitive to micrometric variations (see below), including on large surfaces.
QualiSENSOR® responds to a large number of industrial applications, such as:
Painting and surface treatments
One of the typical applications is the qualification of the orange peel phenomenon.
The latter is characterized among other things by a specific wavelength as shown below.
Plastic & composite materials
Our systems are used to characterize materials: sink marks, welding lines, surface homogeneity, fiber distribution, etc.
Example of class A surface classification:
The classification of two class A surfaces (300 x 300 mm test plaque) in the R&D stage is done in a few seconds with the waviness measurement on the QualiSENSOR® 200.
We defined the quality criteria with the composites manufacturers by correlating the V-Optics waviness index with the customer’s visual perception.

Our solutions allow the control and qualification of this type of material.
Although the paper is not a reflective material, we have set up a QualiSENSOR® 100 at one of our customers in order to adjust the production tools optimally and quickly.
Here the QualiSENSOR® 100 tells us that the sample is compliant because the IQ is less than 7. 7 being the acceptability threshold defined by the customer.
02 Detection of surface defects
Any defect modifying the surface can be detected by the QualiSENSOR®; whether this results in a deviation of shape or a difference in brightness, reflectivity.

On the right, the QualiSENSOR® image highlighting the frosted area and allowing robust automatic detection.
A plastic injection manufacturer wants to automate his control in the production line with the QualiSENSOR® 200 to scan parts coming out of the press.
The example below shows a class A part rejected by QualiSENSOR® following the detection of a scratch too large to be acceptable.
03 The flatness measurement
QualiSENSOR® is also capable of measuring the flatness of reflective surfaces (mirror, glass, metal, ceramic, etc.).
The example below illustrates the measurement of the flatness of a silicium 100mm diameter wafer in seconds with nanometric precision.
Some examples of possible layouts:
Use of QualiSENSOR® 100 in off-line and in the laboratory with support to be placed on a table.
Use of QualiSENSOR® 100 in production line on static gantry or robotic arm.
Use of QualiSENSOR® 200 in off-line and in laboratory, in cabin.
Option on QualiSENSOR® 200 in the cabin: grazing light layout for scanning dull surfaces.
Use of QualiSENSOR® 200 in production line on static gantry or robotic arm.
