Filter glass for eye protection from lamp working can be prepared by doping elements that absorb the visible and infrared light. In commercial filter glass studies, cobalt oxide and rare earth are usually doped in filter glass. In the study, the filter glass was made of clear glass with a composition as glass lens then doped with CoO 0.02 , 0.04, 0.15%wt and Pr2O3 0.5, 0.8, 1.2, 2.4, 3.6, 4.8 %wt per 100 grams glass respectively. The resulting glass was characterized by UV/is spectrophotometer. It showed that the glass could absorb UV/is and IR light in the range of 250-2500 nm similarly to the commercial one. Moreover, it was found that doping CoO 0.15 %wt and Pro 4.8 %wt could reduce the transmittance to 10.7% at the wavelength of 594 nm and 59.3% at the wavelength of 1620 nm. These results presented that the studied filter glass could be developed as protection equipment for lamp working.
