MICROLENSES

摘要

Microlenses which are easy to handle are produced by providing rotation-symmetrical recesses in a glass plate, depositing vitreous layers by means of a vapor deposition process onto the plate, until the recesses are fully filled up, whereafter the thickness of the coated glass plate is reduced to the original value or to a smaller value. Two lenses produced in this manner are then combined to one lens by placing the embedded lenses on top of one another by means of their flat sides.
