Reflective surfaces: QualiSENSOR Compact and Monitor
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: the Compact and the Monitor.

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 Monitor.
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 Compact at one of our customers in order to adjust the production tools optimally and quickly.
Here the QualiSENSOR Compact 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 Monitor 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 Compact in off-line and in the laboratory with support to be placed on a table.
Use of QualiSENSOR Compact in production line on static gantry or robotic arm.
Use of QualiSENSOR Monitor in off-line and in laboratory, in cabin.
Option on QSM in the cabin: grazing light layout for scanning dull surfaces.
Use of QualiSENSOR Monitor in production line on static gantry or robotic arm.
Transparent materials: QualiLENS 200 and 400
QualiLENS 200 and 400 is used to characterize transparent materials such as:
- Windshields / canopies
- Bottle preforms, flasks
- Lenses and optical windows of all types

Each user may have different applications and therefore different needs, we exclusively design tailor-made systems.
The features:
01 Defect detection
Any aesthetic and / or functional defect of the transparent material will be detected and evaluated by the QualiLENS 400 in a few seconds.
Some application examples:
Bottle preforms, flasks
In this case of application, QualiLENS 400 detects and measures scratches on a plastic container used for blood analysis. Thus the parts checked after injection reveal tool or process faults.
30mm diameter sapphire watch glasses
Our system allows the automation of watch glass control by detecting dots, scratches and inclusions.
The faults are identified and located by the QualiLENS 200 automatically.
02 Characteristic measurement
Characteristics such as optical distortion are important parameters in a good number of industrial processes: windshields, aeronautical glazing, etc.
QualiLENS 400 is particularly suitable for this characterization by its technology.
Windshields
QualiLENS 400 measures optical distortions on an entire glazing and locally.
The results provided by QualiLENS 400 are compatible for products / processes subject to the ECE R43 standard.
