EASYSENSE Laser module with Optical slides

EASYSENSE unit will automatically go into sleep mode between readings so the power

supply to the Laser module will be interrupted and the Laser will switch off.



The Laser diode produces a fixed focus oval beam of light. When conducting a Young's

slit investigation the beam of light should be orientated to match the slit.

Optical Slide information

There are two optical slides supplied with the Laser module.



The slides should be used with the front image facing towards the Laser module to

reduce back scattering of the laser beam.

Note: If the letters appear reversed the slide is the wrong way round.



The Laser module should be set up within 5cm of the optical slides surface for the best

results.



Handle the slide by its mount only. Mishandling will damage the film.
