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 -70 and 200mm (in case the sampling cycle is 20s), or between 100 and 200mm (in case
the sampling cycle is 10s).
*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 0.08% F.S. or less.
*5 Terminate a laser beam using a diffusely reflecting material or by an absorber regardless of the safety distance.
