About This Product
A visible beam lets students compare a real light path with the ray diagram they have drawn, whether the beam is bouncing off a curved mirror or bending through a block. With a grating or slit in place, the same laser produces diffraction and interference patterns on a screen.
Frequently Asked Questions
What precautions apply to the Green Diode Laser?
Do not look into the beam or point it at eyes, faces, reflective jewellery, polished metal or uncontrolled reflective surfaces. Use it under supervision and switch it off straight after the experiment.
