^1 The laser classification for FDA(CDRH) is implemented based on IEC60825-1 in accordance with the requirements of Laser Notice.The resolution of the height (distance from head reference plane to measurement workpiece) is 1 µm(2). ^2 This is ±3 σ value (Auto Maintenance Mode is OFF) when the average height of a single rectangular area(3) has been measured for 30 seconds using a KEYENCE standard target. ^3 The rectangular size is WI-001 : 0.3 mm × 0.9 mm 0.01" × 0.04", WI-004 : 1.1 mm × 3.7 mm 0.04" × 0.15", WI-010 : 3 mm × 9 mm 0.12" × 0.35". ^4 This is σ value (Auto Maintenance Mode is OFF, Capture Timing is “Prioritize Accuracy”) when the average height difference of two rectangular areas(3) has been measured for 30 seconds using a KEYENCE standard target. ^5 This is the value (Auto Maintenance Mode is OFF, Capture Timing is “Prioritize Accuracy”) when the average height difference of two rectangular areas(3) has been measured using a KEYENCE standard target. ^6 The workpiece stopping time at capturing is 120 ms (High Speed Mode) or 240 ms (Standard Mode).
