WebWitness Samples Custom witness samples available in standard 1″ or 2″ diameters as well as custom sizes. Best practices suggest that when coating or setting up an optical component, it’s best to use a witness sample, also called a “test piece,” to ensure that the actual part will match your specific coating specifications and your application. WebThe most desirable practice with the witness sample glass is to measure the actual piece to be used for the deposition and then apply the test deposition. Alternatively, the witness glass can be partially masked before coating, so that there is an uncoated area for measurement on the part with the test deposition. fly me to the moon tuto piano
