Optical surface measurement (Interferometer)


Measurement of surface topography in nanometer scale-thickness measurement of thin films- surface roughness and form measurement.

This device measures materials surfaces with the white light interferometry technology. White light interferometer is consisted of a white light source, optical system and a CCD sensor.
Based on this method, the measurement range varies from 5 nanometers to few millimeters. Accuracy and precision depends on source light coherence, vertical stage accuracy, vibration of the table, specimen reflection and roughness and CCD sensor error. Considering abovementioned factors, Achievable accuracy is 5 nanometers.

About Us

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.
