Thin film deposition thickness measurement on materials up to 2 nanometers accuracy
This device is able to measure coatings and thin film layers on different surfaces up to 2 nanometers precision. Principles of optical diffractometry of phase steps is used for the measurement.
This device is consisted of a Laser with 5-15 mW is used in order to supply light source (with two different wave lengths in the first device), beam expander containing two lenses with a pin hole of 5 micron linear accuracy, goniometer with the precision of one minute in an angle, motor for angular variation and encoder, three axis holder of sample and CCD, CCD sensor with 5 micron pixle size, metal and fiberglass device cover, image processing software.

Fanavari Kahroba Company started its activities in 2011 with manufacturing EMC Camera device and began to be a member of science and technology park of University of Tehran since 2012. Later on with devising thin film thickness measurement device and far distance Moiré measurement device, its official activities in precis measurement industry begun. Its optical surface topography measurement devices was introduced in 2014. Thanks to first ranked graduate elites, Kahroba’s company has devised several products with no international competitors. In addition, its products have the advantage of consumers support, precision calibration and being financially affordable for local manifactures. Among the highest valued policies of Kahroba’s company, science management can be mentions. Its most precious investment is expert graduate researchers. Reaching high shares of optical based measurement devices in the international market is one of the perspectives of Kahroba’s company. This aim not only does increase national economical growth, investment return and export, but also it does help to improve scientific foundation of the country and creating more job opportunities. In order to achieve this goal, Kahroba’s mission is devising high precise optical based measurement devices without international competitors based on national scientific experts.
