“…The analysis of the spectra obtained for several light sources is presented in the figures [5][6][7] Figure 5a represents the dark spectra recorded in order to know the background noise and to confirm the individual spectra from respective samples. While recording dark spectrum, the VIBGYOR colours are obtained in the spectrum due to the presence of green light in the webcam as shown in the Fig.…”

“…Usage of webcam is to overcome the tedious arrangement of grating and prism. The cameras on smartphones have automatic adjustments for focus and white balance making it difficult to obtain consistent readings [6][7][8]. There have been several reports attempting to characterize the camera sensor to carry out reliable measurements.…”

Increase in the population demands healthy food, clean air, fresh water and high secured life. To fulfil the above demands, spectrometers such as ultraviolet, Fourier transformation infrared, Raman, HPLC, gas chromatography are used as confirmation tool for identification of materials. The cost and space of above-mentioned instruments are more and to build low-cost spectrometer with high efficiency is a challenging research area for material scientists and engineers. In the present work, an attempt has been made to manufacture a low-cost spectrometer. The spectrometer has been designed using cardboard, DVD, a webcam and free available spectrum software named as theremino. The DVD is used as a diffraction grating and webcam as an image sensor with an overall cost of Rs 1000. This can be used as an instrument for practical demonstration for students and other research purposes for detecting pesticides level in fruits and vegetables, sensing water purity level, edible oils, etc. The spectral range can be improved by removing infrared filter integrated in webcam. The performance of the constructed spectrometer could be upgrade using effective filters and high intense low-cost lasers. This designed spectrometer will be a boon towards application in healthcare, biomedicals and food processing applications.

Spectroscopy is a method that used to identifychemical structure of substances using its spectral patterncharacteristics. Optical spectroscopy term can be applied to anykind of optical photon interactions with matter. Ramanspectroscopy essentially shows spectral response like thewavelength of scattered light is shifted regarding initializingexcitation wavelength. In this paper, we propose a design of lowcost optical-electronic sensor based on Raman spectroscopy.This low cost optical-electronic sensor employs a violet-blue 405nm wavelength laser diode, a biconvex lens with 5 cm diameterand focus point, a test tube, and a Complementary Metal OxideSemiconductor (CMOS) sensor. We tested this low cost opticalelectronic sensor based on Raman spectroscopy in darkcondition. Combination of these hardware and components canprovide measurement result to any liquid sample. From thisexperiment, even all liquid samples that used to test thiscombination of hardware and components are transparent, theystill have different Raman spectra. This combination ofhardware and components can be implemented into someapplication for instance body liquid measurement such as blood.In specific application, we need to employ data analysis and abunch of data set which are organized into three different groupsuch as training data, validation data, and test data group,combined with this developed instrumentation.
