Description
Poisson/Arago Spot DOE Teaching Demonstration Experimental Equipment Diffraction Grating Interference
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.
