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 0.0 and 50mm (in case the sampling cycle is 20

s at diffuse reflection), between 0.0 and
42mm (in case the sampling cycle is 20

s at specular reflection), between 36 and 50mm (in case the sampling cycle is 10

s at diffuse
reflection), or between 36 and 42mm (in case the sampling cycle is 10

s at specular reflection).
*3 The figure shows the value at measurement center distance. It is determined by 1/e
2
(approximately 13.5%) of center beam intensity.
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.
