Instrumentation

Light sources (e.g. LEDs) and lasers are used in a wide range of applications: R&D, optogenetics, medicine, automotive, telecommunications, etc. Very precise analysis of these sources is therefore highly recommended in order to check their specifications (position, beam shape, pulse duration, time drift, etc.). To do so, we propose several solutions:

  • Laser beam analyzers

    Laser beam analyzers (5)

    Analyze the profile of your laser beams with our turnkey imaging solutions Spectral range of measurement: from 190nm to 16um

Laser Beam Analyzers It captures, displays and records the spatial intensity profile of a laser beam in a particular plane transverse to the beam propagation path. Since there are many types of lasers - ultraviolet, visible, infrared, continuous, pulsed, high power, low power - there is a wide range of instruments available. No laser beam analyzer can handle all the power levels, pulse duration, repetition rate, wavelength and beam size of lasers on the market.

  • Chromatic Sensors & Interferometry

    Chromatic Sensors & Interferometry (8)

    There are different techniques to carry out distance and thickness measurements at very high rates. The principles of confocal chromatic and interferometric confocal imaging allow the measurement of virtually any type of surface or material. The use of infrared and white light sources extends the range of possible applications. Which is the right choice for your application?

Chromatic Sensors & Interferometry It may be necessary to check the surface condition of a material after using a Laser to texture it for example. Depending on the material, a non-contact analysis is preferable. Our chromatic and interferometric sensors are perfectly suitable. There are different techniques to carry out distance and thickness measurements at very high rates. Confocal chromatic and interferometric confocal imaging principles allow the measurement of virtually any type of surface or material. The use of infrared and white light sources extends the range of possible applications.

Infrared viewers & maps These visualization instruments will allow you to quickly and cheaply know the position and shape of your laser beams.

  • Mirrors & Deformable Lenses

    Mirrors & Deformable Lenses (3)

    A deformable mirror is a component that reflects light by introducing spatially controllable optical delays (or advances) on wave surfaces. Applications are numerous, ranging from microscopy to astronomy, ophthalmology to laser pulse shaping.

Mirrors & Deformable Lenses : The analysis of a Laser can lead the user to want to correct the shape and/or the position of its beam. To do this we offer deformable mirrors and lenses. A deformable mirror is a component that reflects light by introducing spatially controllable optical delays (or advances) on wave surfaces. Applications are numerous, ranging from microscopy to astronomy, ophthalmology or laser pulse shaping.

Active stabilization of laser beams These solutions include control electronics, an angle and position detector and two active mirrors that form a feedback loop to suppress thermal drift and the rapid fluctuations that can occur with a laser source. This allows the position of a laser beam to be maintained with sub-micrometer accuracy.

Optical Metrology

The optical properties of light make it possible to quantify distances, deformations, displacements for example, but also to analyse different types of materials. All these measurements belong to the field of optical metrology. Discover below our different solutions for the analysis of matter:

Surface metrology AltiSurf© surface metrology instruments combine the metrological approach and optical microscopy in a 3D cartography, via the taking of successive profiles by scanning a chromatic confocal measurement point or a stylus with low support force. Derived from the notion of roughness well known to mechanics, the in-depth knowledge of the valleys and peaks of the surface studied allows researchers and engineers to establish diagnoses of quality, functionality, aesthetics of their product or material with a new metrological approach. This approach includes new surface roughness parameters which are currently establishing the new measurement standard ISO 25 178 within ISO International through the work of the standardisation committees. These systems also incorporate high-precision motorized plates to scan all types of samples.

Industrial Microscopes The fast and accurate analysis of the surface condition of a material is often required to validate the proper functioning of a machine tool for example. Our various solutions(upright, inverted, stereomicroscopes, interferometrics, measurement...) will certainly meet your needs.

Control by Ultrasonic Laser These tests (LUTs) combine the sensitivity of ultrasonic inspection with the flexibility of optical systems to meet complex inspection challenges. They can test metals, composites, ceramics and liquids. Inspection is performed remotely and quickly on curved surfaces, fixed or moving parts, in hostile environments and at temperatures well above those tolerated by other instruments. The accuracy and flexibility of Ultrasonic Laser Inspection makes it an exciting new option in the Non-Destructive Testing (NDT) market.
