Stil's confocal chromatic sensor CCS Prima is now available in 2 or 4 multiplexed channels version. The CCS Prima 2 and CCS Prima 4 allow the user to connect up to four optical pens, and to enjoy both a multiple measurement range and/or multipoint measurements on one sample with a single controller. Thanks to a fast commutation, this single controller opens the way to instantaneous and automatic commutation from one measurement to the next.
