Use of digital photo devices in optical spectral analysis

Abstract

The aim of the study is to increase the potential of available and prospective devices for optical spectral analysis. Mounting layouts for obtaining optical spectra using digital cameras were developed. An installation on the basis of steeloscope SL11-A with a digital camera was designed as well as working dummies of spectrographs using digital cameras. The second installation is a classical scheme of a prism spectrograph on the basis of digital camera SAMSUNG WB 500. A replaceable diffraction grating may be used instead of the prism. The third unit consists of two parts - the spectroscopic part consisting of micrometric slit lens, Amici prism, removable concentrator and reflex digital camera SONY SLT A55V. The methods of work included physical - technical modeling and design. Spectra of light passing through various filters. Digital spectra obtaining is required for further automation of the measurements Such installations may be applied in the field of spectrography, forensics, astronomy, etc. These may also be used in demonstration experiment and amateur construction.
