The NSA12 actuator is among Newport Corp.'s NewStep series miniature positioning products for automating laser and electro-optic experiments and processes. Designed to replace manual micrometers, the device enables precise motorized control of a variety of translation stages and mechanically adjustable mounts. Measuring 60 mm long and 30 mm in diameter, it delivers up to 11 mm of travel with submicron increments. The actuator uses a high-torque stepper motor to provide better than 0.3-µm incremental steps at 1 mm/s, with a maximum load of 18 N. The NSA12's nonrotating tip permits large loads to be moved without long-term degradation of the actuator-stage interface.
