The work is devoted to the modeling and calculation of hyperchromatic lenses, which are the basis of confocal surface sensors. The scope of such sensors is very extensive – the sensors allow both precise positioning of the actuating elements for the formation of microand high-quality nanostructures with depths up to several tens of micrometers, and measuring their profile. The modeling based on the chromatic coding method for automatic control of 3D surfaces with high resolution. Calculated, manufactured and experimentally tested three-lens hyperchromatic lens with a chromatic length of 300 μm and a focal length of 24 mm are presented. For the first time in Russia, a prototype of a confocal surface sensor was created on its basis, with an error in measuring displacement of an object of 0.1 μm.
