Unit Of Measurement Output: Height (Z Axis)0.1 μm 0.004 mil
Unit Of Measurement Output: Width (X Axis) 1 μm 0.039 mil (Note):It is a value in which the sensor heads connected to a controller Ver. 2.00 or higher.
Resolution: Height (Z Axis)1 μm 0.039 mil (Note):The value is the average of height measurement in full width at the measurement center distance.
Resolution: Width (X Axis) 5 μm 0.197 mil
(Note):It is a value in which the sensor heads connected to a controller Ver. 2.00 or higher.
(Note)This is the measurement value of a pin gauge rounded surface in the edge position measurement (start of falling edge) calculation setting. The measurement object: white ceramic pin gauge (ø10 mm ø0.394 in), unit light receiving time: 200 μs, measurement value extraction: base light intensity control, average number of samples: 64, width smoothing: ±4, all others are the initial settings.
Linearity: Height (Z axis)±0.1 % F.S.
(Note):Value represents the error in comparison with the ideal line of height measuring range (full scale) for the height measurement of the measurement center position in the width direction. The value in the specifications is the value within ±7.5 mm ±0.295 in of the height measuring range.
Temperature Characteristics 0.02 % F.S./℃
Light SourceRed semiconductor lase (Peak wavelength 658 nm 0.026 mil)
Light Source: Output Max. output: 1 mW
Light Source: Laser Class Class 2 (IEC / JIS / FDA)(Note):This product complies with 21 CFR 1040.10 and 1040.11 Laser Notice No. 50, dated June 24, 2007, issued by CDRH (Center for Devices and Radiological Health) under the FDA (Food and Drug Administration).
Beam Size50 μm × 15 mm 1.969 mil × 0.591 in
(Note):This size applies when using measurement center distance and is defined as 1/e2 (13.5 % approx.) of the center light intensity. Leaked light occurs outside of the defined range; sensing performance may be affected when the reflectance around the detection point is higher than that detection point.
Receiving ElementCMOS 2D image sensor
Indicator: Laser EmissionGreen LED (lights up during laser emission)
Indicator: Measuring Range Yellow LED
[lights up when near the measurement center distance, blinks when within the measuring range, and lights out when outside of the measuring range. (at the measurement center position in the width direction)]
