Publication number: 20180284030Abstract: A system for placing a sample at a predefined measurement location for measuring an optical property of that sample. The apparatus includes a measurement platform for supporting the sample at the measurement location, the measurement platform having an orifice therein beneath the measurement location, and a nozzle configured to retain the sample therein when a vacuum is applied to the nozzle. The sample is contacted by the nozzle, and a vacuum is applied to the nozzle so that the sample is retained therein by air pressure. The nozzle with the sample retained therein is then transported to the measurement location. The vacuum at the nozzle is disabled to release the sample from the nozzle, and a vacuum is applied to the orifice in the measurement platform so as to retain the sample on the measurement platform. The nozzle is then retracted away from the measurement platform.Type: ApplicationFiled: September 29, 2016Publication date: October 4, 2018Inventors: Luke Michael Smith, Brad Cann, Peter Stanley Rose, David Fisher, Juan Abelaira, Philip Maurice Martineau
