Page 39 Product specification notes
*1 Use the ND filter in case the amount of reflected beam is too large.
*2 The measurement range is limited between 0 and 5.0mm (in case the sampling cycle is 20s at diffuse reflection), between 0 and
4.6mm (in case the sampling cycle is 20s at specular reflection), between 3.8 and 5.0mm (in case the sampling cycle is 10s at diffuse
reflection), or between 3.6 and 4.6mm (in case the sampling cycle is 10s at specular reflection).
*3 The figure shows the value at measurement center distance. It is determined by 1/e
Due to leak light outside the specified area, the reflectance around the detecting point may be higher than at the point and this may
affect the measurement value.
*4 The variation in ambient illuminance is 0.03% F.S. or less.
*5 Terminate a laser beam using a diffusely reflecting material or by an absorber regardless of the safety distance.
