Non-contact measurement with ChromaPoint modular optical heads

CL-MG SERIES

STIL chromatic confocal modular sensor head series represents the perfect balance between technology and precision.

Industrial, compact and robust sensor heads, CL-MG models are available in a dozen of models, each one adaptable to specific environments (e.g. vacuum, heat, water, dust...).

non contact chromapoint modular optical heads
DESCRIPTION

STIL's CL-MG series of optical heads is composed of different chromatic lens models (CL1 to CL6) which, in combination with a variety of six dedicated magnifiers (MG420 to MG20), offer excellent metrological performances (down to the nanometer) for a wide range of applications.

Built to the highest quality standards since 1995, CL-MG series is composed of robust and reliable passive components, suitable for use in industrial and laboratory environments and even in specific environments such as vacuum chambers, radioactive environments or hot environments.

All CL-MG optical heads are available with options such as FOLD to measure at 90° radial beam, and are connected to STIL ChromaPoint controllers such as CCS series, ZENITH, LightMaster or IRIX to measure solutions in multiple application contexts and on any type of surface reflectivity: transparent or opaque, shiny or diffusing.

BENEFITS
  • Dedicated to industrial environment, independent from ambient light 
  • High axial resolution: From nanometer scale (nm) 
  • High lateral resolution: From micrometer scale (µm)
  • High signal to noise ratio
  • Works on a large set of materials, including black carbon, glass, colored or white ceramic & plastics, rough or polished metal
  • Wide choice of measuring ranges
  • Steep slope compatibility thanks to Large Numerical Aperture (NA)
  • Coaxial (no shadow effect)
  • « Speckle » free
