Spectroscopic CO2 sensor using integrating sphere is designed specifically for industrial welding application simulated using ZEMAX®12. Diameter used for the integrating sphere is 2 inch equivalent to 50.8 mm. By using LED as an emitter and photodiode as a detector, CO2 is detected at 4.2 µm which i...
