ImageMaster® HR UltraPrecision – Image Quality Test Station

For ultra-precise measurement of MTF and other optical parameters TRIOPTICS has developed the new ImageMaster® HR UP. It completes the proven ImageMaster® HR product line – the preferred MTF Test Station worldwide. A high-precision air bearing sample holder leads to an increased mechanical stability of the ImageMaster® HR UP. Therefore, an enhanced measurement reproducibility is achieved.
