Request InfoFor Biomedical Applications and Optics InstrumentationPI (Physik Instrumente) LP, Motion Control, Air Bearings, Piezo MechanicsAUBURN, Mass., Jan. 14, 2008 -- Flexure-based piezo actuators such as the P-601 series provide up to 10 times larger travel ranges than classic piezo stack actuators in a low-profile package and with virtually unlimited resolution and lifetime, according to the manufacturer, PI (Physik Instrumente). The stiff construction allows for fast response with rise times much shorter than one millisecond. The design involves no friction, no lubricants and no wear. Because of the many advantages over motor/leadscrew-driven positioners, more and more flexure actuators are used in fast-focusing mechanisms and for other precision...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Nov/Dec 2022 IssueBlue Laser DiodeThe FNV-402-3000M laser diode from Frankfurt Laser Co. is a high-power, 402-nm blue laser diode that delivers output power of >3W.
