To meet what it sees as a need for constant miniaturization and reduction of mass, the co. introduces the LIDA 500 Series linear scales. The new, 20-µm incremental linear scales are reportedly useful where installation space is limited and offer measuring steps of 1 to 0.1 µm., their reduced mass giving them higher dynamic capability. Two models, the LIDA 583 and the 573, each have two smaller scanning fields with double-field scanning. The signal is corrected online electronically, the co. notes.
