TZTEK is a leading manufacturer of image measurement instruments in China. Its self-developed and produced VM series of automatic image measurement instruments are the high-tech products integrating optics, mechanics, and electronics, closely combining with the technologies in following four fields, including precise machinery,electronic circuit control, software algorithms and optical design to achieve accurate measurement.

I. Precise machinery: The self-designed high-precision three-dimensional mobile platform ensures precision measurement.

TZTEK image measurement instrument is designed with high-performance components to reduce precision bottlenecks. For example, the scale system uses British Renishaw''s open grating scales; XYZ three-axis rails use Japanese THK''s precision linear slides and precision transmission mechanisms. Due to the small deformation and high stability of granite, TZTEK image measurement instrument uses granite as the main structural material.

II. Electronic Circuit Control: The dedicated electronic control system for the self-developed image measuring instrument has high reliability.

TZTEK CNC control system integrates various functions such as position control, light source control, movement control and speed control, and has obtained national intellectual property patents. It can effectively control and drive each moving part of the image measurement instrument, and quickly feedback the position data and status information of the machine to the measurement software to ensure efficient and accurate measurement. In addition, the TZTEK image measurement instrument adopts the motor driver that acquires independent intellectual property right to realize the current loop in the control loop and achieve the constant current start and operation of the motor.

III. Software algorithm: Independently develops software for image measurement instrument and obtains Chinese software copyright.

The core members of the company''s R&D team are all from world-known software companies and have a strong technical background. The independently developed Vispec measurement software has more than 30 powerful functions such as geometric extraction tools, primitive replication, multiple data output methods, multiple instrument control methods, integrated SPC functions, DXF drawing loading, automatic contour tracking, panoramic scanning, and drawing comparison to ensure high-precision, high-efficiency, and high-stability measurements.

IV. Optical design: It independently designs the three light source including surface light source, contour light source, and coaxial light source.

TZTEK automatic image measurement instrument has 6-ring & 8-zone annular surface light source. Each segment is controlled independently, with the brightness level up to Grade 256, and the incidence angle of each ring is different, ensuring that different lighting methods can be provided for different workpieces. Contour light illumination produces a strong contrast, which clearly gives the contour of workpieces. In addition to the surface light and the contour light, TZTEK automatic image measurement instrument is added with coaxial light illumination, so that it can be used to measure the depth of workpieces and the depth of blind holes, and allowing it to have a unique effect on the measurement of reflective and mirror workpieces and a strong auxiliary effect on the accuracy of crawling primitives.
