Laser Positioning System

Laser Positioning System (LSP) was designed for precision and accurate patient alignment during X-ray and ?-ray treatment. The System consists of three boxes in which there are five modules with long life laser diodes (Sanyo, Japan). The System can work continuously for years without special service. Two boxes with help of special cylindrical lenses generate light crosses on both sides of table with patient, third one with light lines is for control of the table axis. The System is safely powered from 5 V DC (special adapters 220V AC/5 V DC are included). Fine mechanical positioning rails are helpful for adjustments of the System during installation and after that no special service is necessary.

Moduł laserowy
laser diode module with stand which emits
collimated light beam at 655 nm wavelength ( red color )

power pack with input voltage of 5 V used for supplying the laser module

optical elementsElementy optyczne
  • Lenses (3 pcs) each with different focus: 2 convergent and 1 divergent
  • Standard diffraction grating with a constant d = 10.0 um +/- 0.1 um
  • Diffraction grating of unknown constant (destined for investigations)
  • Glass Plates (3pcs)
  • Polarizing foil (2 pcs)
holders Uchwyty mocujące
  • mechanical holder for diffraction grating, polarizers etc. with a stand
  • mechanical holder for lenses with a stand
detection set UD 1Miernik
  • Photodiode with a stand
  • Multimeter


The Set allows to carry out several optical experiments like:

  1. measurements of the parameters of the lenses
  2. polarization of light by absorption and verification of Malus law
  3. polarization of light by reflection and measurements of Brewster angle
  4. polarization of light by refraction
  5. optical activity of sugar solution
  6. single-slit diffraction and measurement of thickness of hair
  7. diffraction and interference by example of diffraction grating and evaluation of its parameter
  8. measurements of refractive index of the prism
  9. measurements of critical angle for air-glass boundary using a prism

In order to help in experiments a special 25 pages handbook is added in which there is theoretical background for experiments as well.

Price of the Optoelectronic Set is 450 EURO plus 50 EURO as a cost of delivery via Express Mail. The order may be sent directly to Sensomed Company by fax. The Optoelectronic Set will be delivered within one week as an Express Mail parcel with original invoice attached. The payment should be made within two weeks as a bank transfer of money.
