Portable roughness tester

The main proposals for discussion: adjustment of the development to the requirements of the customer, joint development of the development to the industrial level, production of the development to order.

Sphere of implementation and application of the project (startup): chemical industry, electronics, mechanical engineering, instrumentation, microelectronics, nanotechnology, optics.

Project implementation area (startup): Development of modern information and communication technologies, robotics.

Description of the project (startup): The principle of operation of the system is based on a change in the transverse coherence function of the field reflected from a rough surface in the scheme of a polarization displacement interferometer. Since the field in such an interferometer is compared with itself, the deviation of the surface shape from a flat one practically does not affect the measurement accuracy. This allows you to control surfaces with curvature radii up to 200 mm. The resolution for the standard deviation of the profile from the baseline Rq is 0.001 µm. The boundaries of the measured heights by Rq are 0.002 – 0.15 µm.

Markets targeted by the project (startup): Enterprises, institutions, organizations on the territory of Ukraine and abroad.

Description of the problem solved by the project (startup): control of surface roughness of large parts; on-line control; deviation of the shape of the controlled surface from a flat one is allowed.

Technical result: Model sample.

Competitive advantages and novelty of the project (startup): speed – one measurement per second (possibility of real-time control); vibration resistance (the ability to install the system directly on the machine that manufactures the part); indestructibility; compactness.

At what stage is the project (startup): Breadboard sample.

Approximate cost for the implementation of the project (startup): UAH 1.2 million.
