• With a head signal pitch of 400nm, interpolation error is virtually non-existent.
Note 1: The items marked by an asterisk indicate the machining dimensions on the mounting surface. Note 2: The surface roughness of the scale mounting surface is Rmax = 6.3 S (250 μinch).
Note 3: The surface roughness of the detector head mounting surface is Rmax = 12.5 S (500μinch). Note 4: "M" refers to the machine guide.
Note 5: When mounting the reference plate (reference plate W), adjust the plate so that the parallelism between the corresponding scale abutting surface and the machine guide is 0.01mm or less.
Applications: High-accuracy microscopes, stages, measurement equipment.
