The ChromaLine MPLS is the only multipoint chromatic confocal sensor on the market. It achieves a very high throughput by measuring a large number of points simultaneously.
In order to conserve the high resolution and high “cross-talk” rejection characterizing the confocal setup, each point on the line should be measured by means of an independent channel. Confocal setup also requires the distance separating two adjacent spots projected on the sample surface to be greater than the spot diameter.
ChromaLine MPLS principle of operation:
The MPLS multipoint chromatic confocal sensor consists of 180 independent chromatic confocal channels. Each channel comprises its own point source S, pinhole S” and spectrometer, and measures a single point S’ on the sample. The chromatic lens is common to all the channels.
The 180 point sources are achieved by using 180 optical fibres which are illuminated by an internal light source inside the controller. The fibre optic bundle is connected to an optical head, and the other ends of the individual optical fibres are arranged in a line in the input plane of a chromatic lens which projects their images on the sample surface.
The light beams which return from the sample are collected by the same chromatic lens which focuses them on 180 pinholes located on its output plane. A second fiber optics bundle connects the pinholes to the spectrometer.
