™™○ The CDX series sensor heads mentioned above are products to which limits on resolution have been added to enable their non-applicability to “Export Trade Control Order Appended Table 1 2-(12) Measurement devices.” For applicable products with no limited resolution, refer to here.

Measurement conditions
The measurement conditions are as follows unless otherwise designated:
Ambient temperature: 25°C (normal temperature), Supply voltage: 24 VDC, Sampling period: 50 μs, Moving average performed: 256, Median filter: 31, Center of measurement range,
Measurement target ([specular reflection: glass] for the 15 mm/30 mm type, [specular reflection: aluminum vapor deposition mirror] and [diffuse reflection: visible light shielding ceramic] for the 85 mm type) Furthermore, the sensor head is fixed in place with an aluminum jig when measurements are performed.

*1. The measurement range will become narrower when the sampling period is set to the maximum speed of 12.5 μs. Please use by selecting from Near/Center/Far below.

*2. In accordance with the FDA provisions of Laser Notice No. 50, the laser is classified as Class 1 per the IEC 60825-1:2007 standard.

*3. Defined with center strength 1/e2 (13.5%) at the center of measurement range. There may be leak light other than the specified spot size.
The sensor may be affected when there is a highly reflective object close to the detection area.

*4. The minimum step that can be identified when the distance between the sensor and target changes one step at a time (when performing moving average 65,536 times)

*5. Peak-to-peak value of measured value when measuring in stationary state (when performing moving average 65,536 times)
