  • How to Push Efficiency Using Laser Triangulation Sensors
    Laser triangulation sensors project a red or blue laser beam onto the surface. The light reflected from the spot is imaged by an optical receiving system onto a position-sensitive element in the sensor. If the sensor or the measurement object are moved towards the laser beam, the laser sensor
  • The PRIMA fringe sensor unit
    after beam combination and a very-low-resolution spectrometer without photometric channels. It consists of two identical fringe sensors for dual-star operation in PRIMA astrometric mode. Methods. Unique among interferometric beam combiners, the FSU uses spatial phase modulation in bulk optics
  • Laser Engraving Equipment - Features, Accessories and other Must-haves (.pdf)
    be focused to its smallest spot size at the point where it contacts your material. Auto-focusing the laser beam is simply a matter of using a motorized table lift and a sensor to move the table up or down until the top of the work surface is the correct distance from the focus lens. Manufacturers use
  • Machine Vision: Seeing (Electronically) Is Believing
    and Thru-Beam sensors, with choice of cable or quick disconnect. Omron s ZX laser measurement sensor system features a single amplifier unit that supports 11 different sensing heads interchangeably, eliminating the need to purchase unique amplifiers for each sensing head. Heads available include eight
  • Photodiode Characteristics and Applications (.pdf)
    sensors, beam alignment, surface characterization, laser range finders, optical communications, and medical imaging instruments.
  • Linear Actuators for High-Speed Low-Load Applications
    are available, accurate positioning at high speeds is still difficult with pneumatic systems. High-speed linear actuators that use disc magnet motor (DMM) technology, however, provide excellent linear speed for low-load applications such as sensor movement, positioning a laser beam, pick and place
