Optical beam Positioning


Preview

  
Under the trade name of SpotOn we offer a wide variety of computerized position measurement systems. This is a family of cost-effective and versatile solutions to numerous industrial and laboratory applications.

Among the measurement applications, are:
  • Measure laser power and centration or displacement
  • Align beams and QC of optical systems
  • Measure target rotation and displacement
  • Monitor vibration, deflection and motion

The advantages:
  • A simple, fast and cost effective means to control laser beams in real time
  • Transforms your personal computer into a powerful measurement instrument.

Optical beam position measurements can be done by a variety of sensor heads, including:
  • CCD's or
  • Miniature and Large Area PSD's

These are offered over a broad wavelength range, from the deep UV through the near IR. Each sensor head can be equipped with an appropriate optical filter to improve its performance. The accompanying electronics allows interfacing to a computer via a variety of plug-in cards, like: PCI, PCMCIA or ISA bus. For harsh industrial environment we offer a complete stand alone system.

The standard SpotOn program user interface includes a numerical and graphical presentation of position and Power, long term fluctuation (Strip Chart type), and a communication protocole via RS232.

Several types of detectors are used for sensing the position of a beam's centorid incident on the detector's surface:
  1. CCD type of detector
  2. 4-Quadrant detector
  3. Dual axis Lateral Effect detector
Duma Optronics offers a variety of sensor head sizes to accommodate numerous application needs.

SpotOn comprises of:
  • A PSD detector head (Lateral Effect/ Four Quadrant/ CCD)
  • A PC compatible plug-in card (ISA/ PCMCIA / PCI)
  • A software package for Windows

Main Features:
  • Precise: 1 µm accuracy, sub-micron resolution
  • Versatile:
    • Measures both Position and Power
    • 3 Types of plug-in cards are available
    • A variety of sensor head types and sizes
  • Easy to use: Simple installation, user friendly software
  • Convenient: Works with any PC computer under various Windows platforms
  • Simple interface: with other programs like Excel and LabView
  • Enhanced software features: Data recording, statistics, RS232 Link to another computer, printing

Industrial Solutions:
In the effort to provide better solutions for measuring the position and power of laser beams for places with limited room, the Stand Alone versions are offered, featuring:
  • Rugged small footprint device
  • Simple to operate
  • Perfect for factory floors, areas where shock and vibration are common and too harsh for a commercial PC
  • Data storing and RS232 link to another computer

Analog Beam Positioning:
Spoton Analog is a complete solution for fast and extremely accurate laser position sensing, where main applications are:
  • Measure laser displacement in real time, at a rate up to 30 kHz bandwidth for 9mm X 9mm, or up to  60 kHz for 4mm X 4mm
  • Measure fast steering mirrors 
  • Monitor vibration and deflection at high bandwidth from long stand-offs
  • Perfect for close loop applications
