Request InfoPI (Physik Instrumente) LP, Motion Control, Air Bearings, Piezo MechanicsThe V-731 reference class XY stage from Physik Instrumente LP is a new addition to its PIMag series of high dynamics linear motor stages. The device is equipped with incremental linear encoders for direct position measurement and three-phase electromagnetic linear motors. 10-nm resolution and precision-crossed roller bearings with anticreep cage assist guarantee repeatability to 100 nm from this compact, low-profile stage. PIMag stages do not require mechanical components in the drivetrain as the force is transmitted directly by magnetic forces to the motion platform without...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra December 2020 IssueLinear Motor StagesThe V-817 series of linear stages from Physik Instrumente LP are three-phase linear motors well suited for precision automation applications such as sensor and camera positioning, laser welding,...Photonics.com 12/9/2019XY StagesIntegrated XY stages with mechanical bearings from PI (Physik Intrumente) LP are engineered for heavier loads and available with three-phase linear direct-drive motors.

These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookAcousto-Optic Devices: Charts showing the characteristics of acousto-optic scanning devices, acousto-optic figures of merit, and solutions for common problems with acousto-optic processor devices.ACOUSTO-OPTIC SCANNING DEVICES: CHARACTERISTICS MODULATORS Material Bandwidth (MHz) Rise Time (ns) Acousto Input Power (W) (Saturation) Material Wavelength Range...Photonics HandbookFlat Optics: Considerations When Buying: To simplify the process when purchasing flat optics, we will discuss the top six factors from a manufacturer’s perspective, all of which affect the three major areas of the purchasing decision: quality, delivery and cost.Flat optics generally perform three main functions: They transmit light (windows), reflect light (mirrors) and fold light (prisms). While most optical manufacturers make spherical and flat optics, a...Photonics HandbookOptical Delay Lines: Key to Time-Resolved Measurements: To obtain an accurate means of creating reliable delays in any time-resolved spectroscopy or dynamic experiment, several factors about the delay line stage must be considered to reduce or eliminate errors associated with linear stages.One of the most critical elements of any time-resolved spectroscopy and dynamics experiment is the optical delay line. A typical optical delay line consists of a retroreflector or folding mirrors on...WHITEPAPERSPhotonics.com 1/31/2020Colored Glass as a Versatile and Economical Means for Optical FilteringColored glass filters find many uses in optical systems including imaging, laser, and industrial equipment.
