Features include a scanning unit and two types of scales. The scanning heads come with a 1 V peak-to-peak analog interface, with TTL digital version planned this year with up to TTL x 2000 interpolation as a possibility. Position noise is measured to +/- 0.04" (arc seconds). The two types of scales contain a 20-micron graduation with a full circle and segment of a circle. For the circular scales, a disk with 2,500 lines per revolution with an outside diameter of 19mm version is now released.

For the segment shaped scale, it has the same graduation of 20 micron, but is lighter in weight as portions of the glass disk have been removed to shape the scale into its rectangular form. The smaller diameter disks are mounted with a pin, and epoxy is recommended to solidify the mounting. The mechanical speed limit for the disks is up to 14,000 RPM. All disks will have a reference mark and the graduation is Supradur, which is a graduation designed to be resistant to scratches, dust, fingerprints, oil droplets, and other forms of contamination.
