Product Description
Poisson Spot, also known as Arago Spot, is an optical phenomenon caused by the diffraction of light.
When monochromatic light illuminates on a small circular plate or bead of a certain size, annular diffraction fringes of concentric circles will appear on the observation board, and a very small bright spot will appear at the center of all concentric circles, which is called Poisson Spot.
Please do not use high-power laser light source to avoid damaging the grating. - Additional Information
