Polyurethan ir spektrum
WebThe Importance of Using the Correct Material. Since infrared light is comprised of longer wavelengths than visible light, the two regions behave differently when propagating through the same optical medium. Some materials can be used for either IR or visible applications, most notably fused silica, BK7 and sapphire; however, the performance of ...
