Broadband vs Single Wavelength Monitoring

The historical method of calling an end of a layer in optical coating was to monitor a wavelength and when a condition was met calling the end of the layer. In the earliest days this method was done using the human eye of a trained observer. In some cases this is still done today but with the most limited of success. The next advent in coating control came with the advent of the ability to measure automatically the intensity of ...

Spectral Match Cut Points

The historical method of calling an end of a layer in optical coating was to monitor a wavelength and when a condition was met calling the end of the layer. As discussed in a previous application note the NVision optical monitor supports this method with good success. There is one problem with this technology; the measurement of only one wavelength limits the potential precision as we are typically waiting until a condition has been exceeded such as a quarter wave minima or ...

Detecting Cut Points on Challenging Applications

One of principal issues of optical monitoring and control is the ability to handle cut points on difficult or noisy applications.  Making measurements when things are easy is by definition easy!  It gets more difficult when the nature of the actual measurement becomes less stable caused by the actual process parameters.  The following display has been created by an offline tool used at Telemark for testing the cut point algorithm offline.  Notice that the blue trace has some noise but ...

Affordable Broadband Optical Monitoring Tools

Telemark announces the NVision line of optical measurement tools for thin film coating monitoring and control. With over 25 years of history, these tools allow automatic control of optical properties during the deposition process. Real time, broadband optical monitoring and control systems measuring a single measurement point or up to one hundred monitoring locations provide evaluation and control of thin films during growth. This data is highly accurate and laboratory quality.
Each lab quality measurement location operates in real time ...
