Calibration of Infrared Sources with Iran-Made Spectrometer

According to Iran Nanotechnology Innovation Council (INIC), the company has produced a Fourier transform spectrometer with various applications, including calibration of the spectral power of infrared sources.

Fourier transform spectrometers are among the important and practical tools for measuring radiation, absorption and reflection spectra in the nanometer range, and the development and construction of this type of spectrometers is a strategy to deepen the knowledge of material analysis, specially in the field of nanotechnology.

Fourier-transform spectrometers are among the most advanced types of spectrometers that enjoy the capability to measure spectral power in terms of wavelength.

The Fourier transform spectrometer made by the Iranian company is sold in three models of OSA917, OSA926 and OSA1045 with a spectral range of 900 to 4500 nm.

A Michelson interferometer is used in the Iran-made spectrometer which creates a high spectral resolution with the ability to move the driving mirror by a few centimeters. In this spectrum analyzer model, helium-neon lasers are used for high spectral resolution, and constant temperature diode lasers with a wavelength of 630 nm are used for applications that do not require high spectral resolution.

In a relevant development earlier this year, another Iranian technological company had also managed to design and produce a fluorescence spectrometer that is utilized to identify nanoparticles’ materials.

A fluorescence spectrometer, which can be applied in biology, chemistry, and environmental science laboratories, measures the fluorescence of a molecule to gather information about its components and chemical environment.

Amin Sharqi, the technical manager of the mentioned company, said that it is very important to know what kind of materials the manufactured nanoparticles contain during production of nanoparticles.

Thanks to the technology used in building the fluorescence spectrometer, the device is able to detect the particles inside a substance and display it to the user, he highlighted.

Sharqi pointed out that the X-ray hits the material and based on the camera inside it, it can display the elements inside the product.
