Discovery Technology International LLLP has released the NTS NanoDirect series software-controlled piezoelectric linear translation stages. They feature a resolution of 0.4 nm, a travel range of 10 to 100 mm with a velocity of up to 2000 µm/s, an acceleration to maximum velocity time of 0.3 ms, an open-loop mode stability of <2-nm drift per hour at 20 °C and a response time of 50 µs. They can be operated in continuous or stepping mode and in open- or closed-loop mode. Available in three models that offer varying extended ranges of travel, the systems are suitable for fiber optics, metrology, micro- and nanopositioning, and biomedical applications. They come with a digital signal processor controller that is available in one-, two- or three-channel configurations.
