Abstract
A micro-optical element is provided that includes a glass substrate, a microstructure layer, and a bonding strength between the glass substrate and microstructure layer. The glass substrate has a thickness of less than or equal to 1500 μm and exhibits a glue contact angle of less than 45°. The microstructure layer is formed from polymer imprinted on the glass substrate. The bonding strength is larger than 0.5 MPa.
