Request InfoPOG Precision Optics Gera GmbHPräzisionsoptik Gera GmbH (POG) has unveiled stage micrometers made from Ceran glass ceramics that feature good mechanical stability and a thermal expansion of virtually zero. Because of the high contrast of the reflective chrome structures on the dark Ceran background, the micrometers are suited to applications in reflected light. Three versions are available: a 1-mm model in 100 divisions, a 2-mm model in 200 divisions and a 70-mm model with four divisions. Official DKD certification is available as an option.See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Jul/Aug 2023 IssueOptical Testing SystemThe KVC 821 automatic optical testing system from Kistler provides quality assurance diverse sectors ranging from punching and fastening technology to the medical technology industry.
