Nano-Coatings for Optical Elements of Emission and Fourier-Spectrometers
Abstract
Improvement of nanotechnological methods of treating optical components and optielectronic devices provides application of innovation coatings based on oriented carbon nanotubes (CNT) for surface modification. The modified surface of safety glass and optical elements of spectral devices prevent the impact of low-voltage spark on the optical elements, thus increasing their lifetime and improving the quality of the device operation. We present a new method of coating optical elements of the devices aimed at protection and improvement of the transmittance of the optical system. A laser method and experimental scheme of simultaneous application of nanocoatings to 6 pieces of the spectrometers are presented. An example of the experimental scheme with a built-in metallic mesh which provides optimal conditions of laser treatment is considered. Data on the change in the transmittance spectrum of the nanostructured CNT specimen valid for emission spectrometers with a working wavelength ranging from 175 to 400 nm illustrate an increase in the transmittance spectrum attributed to CNT-induced surface modification. It is important that indicated spectrum range is characteristic for the internal elements of optical emission spectrometers.
