Used on its own, the LED.laser can be used to investigate reflection, refraction, diffraction and interference.
It can also be driven by the new LED.Modulator, which allows the intensity to be modulated with an analogue signal. The signal can then be received with the LED.Rx, which can demodulate the signal for output to an audio amplifier or oscilloscope. By modulating with a 1MHz signal, the speed of light can be measured directly.
The laser has a convenient flat-bottomed cylindrical housing for work on the bench, and a boss on the back allows mounting on a retort rod.
The wavelength is 640nm, and is a class II unit with a power output of 1mW.
A plug-top power supply and an experiment guide are included.
