Introduction
The EASYSENSE Laser is a solid-state laser module that produces a red light of 645 - 665
nm wavelength. It is designed to be used in optic investigations that require a coherent light
source e.g. Young's slits experiments or single ray optic investigations.
There are two optical slides supplied with the Laser, one is a set of slits and the other a set of
diffraction gratings. Both are suitable for wavelength of light investigations.
The Laser module is not a Smart Q Sensor. The EASYSENSE unit is used to supply power
for the Laser but will not be able to identify it. The Laser module has a push-button switch to
prevent the Laser being turned on by accident.
The Laser module can be used with Smart Q Sensors, such as the Light level or Rotary
Motion Sensor, to provide accurate data collection for optics experiments. It can also be used
as an alternative infrared transmitter for the Smart Q Light Gate to record across a wider area.
Connecting
Push one end of the sensor cable (supplied with the EASYSENSE unit) into the hooded
socket on the Laser.
Connect the other end of the sensor cable to a socket on the EASYSENSE unit.
Set up your investigation. Clamp the Laser module securely and check that the potential
path of the laser beam is not directed to any individual (including you) or into an area
where individuals may wander.
Note: The Laser will not operate until the small push button on the Laser housing has been
pressed
Check the EASYSENSE unit is powered.
Note: If the EasySense unit is in 'sleep' mode (LCD blank), the Laser will not be powered. Press a
button on the unit to 'wake it up' and therefore power the Laser.
Complete all safety checks and press the push switch to activate the laser beam.
Once activated the push switch can be used to turn off the laser beam.
Safety
The cardinal rule of all work with lasers is "never stare into the beam".
ALWAYS MAKE SURE THE LASER IS POINTING AWAY FROM YOU AND NOT
TOWARDS ANYONE ELSE BEFORE PRESSING THE SWITCH.
