EddyCus® TF map 5050SR

Contactless sheet resistance mapping system

The Eddy­Cus TF map 5050SR is a non-con­tact map­ping sys­tem for high-res­ol­u­tion ima­ging of the sheet res­ist­ance or cor­rel­ated pro­pri­et­ies such as met­al thick­ness for sampling areas of 50 x 50 mm (2 x 2 inch) up to 500 x 500 mm (20 x 20 inch). The bench-top device auto­mat­ic­ally meas­ures at vari­ous meas­ure­ments points, typ­ic­ally with a pitch in X and Y of 1 mm (40 mil) gen­er­at­ing ac­cur­ate map­pings of street res­ist­ance or thick­ness across the en­tire sample area. The res­ult­ing high-res­ol­u­tion prop­erty im­ages res­ult­ing from many thou­sands of meas­ure­ment points, con­tains vari­ous in­form­a­tion valu­able for R&D and qual­ity as­sur­ance.

  • Stor­age and ex­port of meas­ure­ment and map­ping data
  • User-friendly PDF re­port­ing for sys­tem­at­ic doc­u­ment­a­tion


  • Con­tact­less sheet res­ist­ance map­ping of thin films
  • Uni­form­ity con­trol and ex­am­in­a­tion of lay­er ho­mo­gen­eity
