KEYENCE Spectral Interference Laser Displacement Meter SI-F01

SI-F Series Spectral Interference Displacement MeterThe SI-F Series Spectral Interference Displacement Meter specializes in super-high accuracy displacement measurement for thickness or position measurement or surface mapping. With resolution down to 1nm, the SI Series is able to see even the smallest defects or changes in position. The fiber type sensor heads are as small as 2mm in diameter and generate no heat and are not influenced by electromagnetic noise for maximum flexibility. Common Applications:• Wafer Thickness• Glass Thickness• Surface Mapping• Stage Positioning• Precision Roller Runout• Warpage/Flatness
