About This Product
On its own, the LED laser serves for experiments on reflection, refraction, diffraction and interference. Connected to the LED modulator, its intensity follows an analogue signal, which the LED Rx can receive and demodulate for output to an audio amplifier or oscilloscope. When the light is modulated with a 1 MHz signal, the speed of light can be measured directly. Export supply of the LED laser can be arranged to laboratories and schools in Malta, Namibia, Côte d'Ivoire, Tanzania, Turkey and South Sudan.
Frequently Asked Questions
Q1. Can the LED laser be used without the modulator?
Yes. It works as a standalone light source for reflection, refraction, diffraction and interference experiments. The LED modulator and LED Rx, available separately, extend it to signal transmission and direct measurement of the speed of light.
Q2. How can the LED laser be positioned?
Its flat-bottomed cylindrical housing stands on the bench, and the boss on the back allows it to be mounted on a retort rod.
