Determination of the Transmission Loss of Nano-crystal and Polymer Complex Thin Films Using Photographic Technique |
| |
Abstract: | A kind of novel nano crystal and polymer complex thin film PT PEK c was fabricated. The transmission loss of the complex thin film was measured accurately and real timely using photographic technique. The method involves a digital camera that has good spatial resolution and corresponding data processing software, the prism coupling system as well. It can be used over a wide range of loss values from 0.5 dB/cm to the order of 100 dB/cm. The transmission loss of nano crystal and polymer complex thin film PT PEK c at 633 nm is measured to be 3 09 dB/cm. |
