Abstract
We demonstrate a novel method for fabricating glass microlens (arrays) with single step on conventional lens surface. In this method, the glass microlens can be achieved by only one step with sol gel glass material. The microlens aperture and focus length can be controlled easily and uniformly. The fabricated sample shows good focusing property. This work will be useful to improve the performance of compound eyes optical system such as camera, telescope, 3D integral imaging and so on.
Highlights
The number of applications for which microlens are used has grown so large it is no longer realistic to provide a comprehensive list
Photoresist reflow which is propagated from planar lithography is not proper to pattern on curved surface
We have demonstrated the technique to fabricate gratings on conventional lens surface. [8, 9, 10] In this letters, we demonstrate a novel method which is proper for fabricating hybrid glass microlens on conventional lens surface
Summary
The number of applications for which microlens are used has grown so large it is no longer realistic to provide a comprehensive list. [8, 9, 10] In this letters, we demonstrate a novel method which is proper for fabricating hybrid glass microlens on conventional lens surface. [11, 12] By sol gel hybrid glass material, the glass microlens can be achieved by only one step without the transferring of microstructure into substrate. [13] The hydrophilic opening is formed in a hydrophobic background by planar lithography, which is not proper to get opening and microlens on curved surface. We can fabricate microlens directly on many types of substrate, the hydrophobic surface, and the hydrophilic glass one
