Optical System for Testing High - Intensity Optical Filters and Welding Shield
Tamal Sarkar, Arindam Mukherjee
Abstract: In this paper, the author reports about a low - cost system developed by the authors to test high - intensity filters for optical and UV regions with due attention to the hazardous aspect of radiation to both the eye and imaging systems. For study purposes, the authors have selected a few standard filters and welding glass shields to observe high - intensity sources, full Moon, and welding arc flames. The author studied the standard filters' transmitted spectrum and intensity cut using the single slit, wavelength splitter (grating), and optical sensors (Web camera and Digital Lux Meter). In the next phase, the author developed optical filters at the Lab using semi - transparent materials like cellophane papers, polymers, thin metal Oxide - Spray - Coating, and their combinations. Based on the spectroscopic studies, the authors found the filters for Welding Shields and other High - intensity Optical Filters with clarity & relief to the eye of an observer.
