I manufacture polyimide tubing and need an in-house method to measure UV absorption of my product. Does anyone know where I can purchase said equipment?
Take small 2"x2" cut portion to any college having Physics education and they will give you result in just 30 minutes and almost for free. It requires Reflection measurement device and a UV source. UV sensitive PM Tube can sense the reflected light. As there will be almost no transmission and remaining will get absorbed in your material. Surface finish sure will affect the reflected light amount. It will also change with time as your material degrades in time.
