The objective lens has its image distance set to infinity. This depth of field is combined with vertical scanning to traverse the surface of a sample providing a high resolution topographical image with a large field of view.  ]]></termNote><termCreatedDate>2026-03-30 20:25:26</termCreatedDate><relation><relationType>UF</relationType><termId>31317246</termId><termName>IFM</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31317247</termId><termName>microscopy, infinite focus</termName><termType>ND</termType></relation><relation><relationType>BT</relationType><termId>31304399</termId><termName>microscopy</termName><termType>PT</termType></relation></term>  </Zthes>
