High resolution non-contact measurement – Innovative Rainbow Probe analyzes the optical spectrum of reflected light to measure surface height changes
Measures where other sensors cannot – Rainbow Probe easily measures transparent, translucent, fragile, liquid or easily deformable surfaces
The right probe for your application – A range of CL-series and RP- series probes are available, each with a unique measuring range, working distance, axial resolution, accuracy, and spot size
An incident white light pinhole is imaged through a chromatic objective into a continuum of monochromatic images along the Z-Axis, thus providing a “color coding” along the optical axis.
When an object is present in this “colored” field, a unique wavelength is perfectly focused at its surface and then reflected into the optical system.
This backscattered beam passes through a filtering pinhole into a spectrograph, which determines the wavelength which has been perfectly focused on the object, and then accuratley determines its position in the measuring field.
The confocal chromatic imaging gives access to reliable, accurate, and reproducible dimentional measurements with extremely high resolution.
