We supply infrared absorbent and color corrected filters for medical and surgical lighting application purposes. The infrared absorbent glass compounded Na2SiO3, CaSiO3, SiO2, Cu2O, CuO, CdO, Au, CO2O3, Ni2O3, MnO2, AgCl/AgBr, etc. formed most types of cylindrical, semi-cylindrical and disk types heat absorbent glass filters. Start from 900 nm of wave length, 85% of IR ray can be absorbed. The filters eliminate most IR ray / heat which generated by the tungsten halogen light sources. The filters will help to hamper bacteria growth under a warm environment which generated by normal lighting. The item be used for medical & surgical lighting apparatus widely.
