Abstract
A device for measuring adhesion strength between a first optical element and a second optical element includes a force gauge, a first magnet, and a second magnet. The second magnet is fixed to the force gauge. The first magnet and the second magnet are configured for magnetically attaching to opposite sides of the first optical element. An attractive force between the first magnet and the second magnet is greater than the adhesion strength between the first optical element and the second optical element.
