Přístroje pro ustavování a kalibraci


The laser interferometer is a highly accurate measuring device based on the principle of light beam splitting. It is most commonly used to measure of machine tool movement, or for their calibration, or to set up them.

The whole system is wireless, including temperature and humidity sensors, making working with all Lasertex devices very convenient, easy, and fast. Another benefit is the lifetime support of the control software.

  • 3D optical measurement for calibration of CNC and CMM machines (positioning, geometry...)
  • 3D measurement of flatness, parallelism, angle and much more
  • Vibration measurement
  • Wireless connection to PC and sensors
  • Easy handling and transport
  • Comprehensive control software (in many languages)

We are an official dealer for CZ and SK.

The basic set of the laser interferometer HPI-3D includes a stabilized laser head, optical equipment for simple linear measurements, wireless temperature and humidity sensors, tripod, PC with software and portable case.

The base set can be extended with a large number of additional components for advanced measurements such as: measuring flatness, straightness of motion, perpendicularity using the 3D method/wollaston method or a flat mirror.

The staff of Control Check s.r.o. will be happy to help you with the selection of suitable accessories, including their presentation.


Straightness of movement






The device selection can be summarized in the following 4 steps:

  • Defining requirements
  • Consultation on a possible solution
  • Demonstration of the machine free of charge (best directly at your company)
  • Recommendation of a suitable machine

Based on our many years of experience, we know that selection of the right measuring machine is a laborious process and you need to consider a number of factors. Don´t hesitate to discuss about it with Control Check employees.

The main factors are: type of production, frequency of measurements, size of the machine, operating conditions and much more. If you are interested in a consultation, don´t hesitate to contact us.


  • Installation
  • Service and maintenance
  • Training (basic, individual)
  • Telephone, online support

As well as the car, house or garden, you need to take care of the measuring technology on an ongoing basis, so that you can always rely on it. That's why we offer to our customers the highest quality service all the time.
We're happy to have if the machines are used for 100%, so we try to accent to pass on you maximum of our knowledge and experience during the training so that you don't bother with any part. If you don't happen to know what to do, we are here for you.

Therefore, do not hesitate to contact us by phone or e-mail, we will be happy to help or explain everything to you. If you have too many of work to do, we will be happy to create measuring programs for you.

In cooperation with Lasertex we provide complete services in the field of laser interferometers. Polish company Lasertex has a significant share in the development and production of laser beam devices, which has been dedicated to more than 30 years. We are the official representative for the Czech Republic and Slovakia.
