POINT SENSORS

In order to optimize the choice of your sensor, it is essential to begin by choosing your optical pen according to your accuracy and measuring range needs.

The optical pen or optical probe is the measuring head of the sensor. It is connected to the controller thanks to an optical fiber.
The various optical pens are defined by different measuring ranges and resolutions.
A single controller can work with several optical pens.

Chromatic Confocal technology is the optimized solution to produce different types of high-accuracy measurements. Each optical pen offers a working distance, a measurement dynamics, a spot size on the target as well as an angular opening of the light beam, making it unique.
Optical pens perform without contact with the target. They cannot alter, nor deform this target when measuring it. Besides, with the right choice of measurement dynamics, there is no need to refocus the light beam on the target for a series of measurement on identical objects.
As chromatic confocal optical pens do not require any energy sources and do not have moving parts, they are – in principle - unalterable and do not require a reset or a zero-setting during a series of measurement.

LINE SENSORS

In order to optimize the choice of your chromatic confocal sensor, it is essential to begin by choosing your optical head according to your applications, your accuracy and measuring range needs.

The optical head is connected to the optoelectronic controller thanks to two optical fibers bundles.
The various optical heads are defined by different measuring ranges, axial resolutions and depths of field.
The optical head combined to MPLS-DM can perform profile measurements independently, without any external translation.
3D measurements can be obtained thanks to translation tables or on a production line.
MPLS-DM offers a very high measuring rate of 360 000 measuring points per second representing 2000 lines per second. Each line is composed of 180 discrete points.
This performance is the result of high level of technological integration, STIL historical know-how and the optimization of advanced manufacturing process.
MPLS-DM sensor provides immediate measurement profiles, each profile including 180 points acquired simultaneously.

VISION - INSPECTION

It is essential to choose your optical head and your 2K or 4K camera according to the desired resolution

Chromaline camera
Perfect Focus insensitive at target movement, vibrations, gread surface defect, slope.
Large numeric aperture allowing high quality imaging even on local slopes.
Hight speed (linear scanning at 85 kHz)
Glass inspection, metal,semi-conductor, plastics
The optical head determines the specificities and performance of the need. It is connected to a light box by an optical fiber channeling the light in line on the object allowing a vision of intensity
The different optical heads are chosen according to the resolution and depth of the desired field.
Inspection vision systems have a dual role:
Provide a good quality image of the surface of the sample with the desired magnification
Process the image to detect and analyze certain predefined features or textures.
As the processing units become increasingly powerful and sophisticated, the basic limitation of current Vision Inspection systems lies in their very shallow depth of field or focus (a few tens of μm or less, depending on the The numerical aperture).
Focusing mechanisms are needed for viewing samples with a larger Z-extension for moving samples.
Chromatic Confocal Microscopy (STIL patent) is a technology that allows the design of optical systems with a very great depth of focus (up to several millimeters). For samples requiring a large depth of field these systems provide excellent image quality perfectly centered.
This technology combines the advantages of color coding and traditional confocal microscopes.
The confocal chromatic microscopes consist of a slit illuminated by a polychromatic light source, a high quality chromatic lens, a beam splitter and a linear B & W photo detector

About us

Company details

For over 20 years, STIL has been creating high-performance optical instrumentation. Inventor of chromatic confocal imaging, a leading technology for non-contact sensors, STIL has designed two families of sensors based on this innovative technology: Point sensors (from 0,1 mm up to 100mm measuring range) and Line sensor (from 1,35 mm up to 4 mm line length with different measuring ranges).
These high-resolution non-contact sensors meet the requirements of the most demanding applications for dimension, thickness or even roughness measurement, both in industry quality control and in research laboratories as high-precision instruments. They can measure any type of sample (transparent or opaque, polished or rough) and any type of material (metal, glass, ceramic, semiconductor, plastic...) and do not require any sample preparation.
STIL innovates through vision technology for fast inspection with "Depth of field" of "PERFECT FOCUS" and develops "à la carte" products for customers worldwide.
