MANUFACTURING OPTICAL ELEMENTS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240042710 titled 'MANUFACTURING OPTICAL ELEMENTS

Simplified Explanation

The abstract describes a method for manufacturing an optical element, specifically a micro-optic lens. The method involves using a substrate with a surface profile that defines flow stop features. A mold tool with a corresponding mold surface profile is used to dispense viscous material. When the mold surface profile and substrate surface profile are aligned, they create an optical element cavity and a peripheral cavity. The peripheral cavity includes flow stop features and an air flow path for air to enter and exit. The optical element cavity and peripheral cavity create a peripheral constriction.

  • The method involves using a substrate with a surface profile and a mold tool with a mold surface profile to manufacture an optical element.
  • The substrate surface profile defines flow stop features, while the mold surface profile corresponds to the desired shape of the optical element.
  • When the mold and substrate are aligned, they create an optical element cavity and a peripheral cavity.
  • The peripheral cavity includes flow stop features and an air flow path for ventilation.
  • The optical element cavity and peripheral cavity create a peripheral constriction.

Potential Applications:

  • Manufacturing of micro-optic lenses for various optical devices such as cameras, microscopes, and sensors.
  • Production of optical elements for telecommunications equipment, fiber optics, and laser systems.
  • Integration into medical devices for imaging, diagnostics, and surgical procedures.
  • Use in virtual reality and augmented reality devices for improved visual experiences.

Problems Solved:

  • Provides a method for manufacturing optical elements with precise surface profiles and flow stop features.
  • Enables the production of micro-optic lenses with high accuracy and repeatability.
  • Allows for the creation of optical elements with peripheral constrictions for improved performance and functionality.
  • Provides a solution for controlling air flow in the peripheral cavity to prevent contamination and maintain optical quality.

Benefits:

  • Improved manufacturing process for optical elements, leading to higher quality and performance.
  • Enables the production of complex micro-optic lenses with enhanced functionality.
  • Provides better control over air flow, reducing the risk of contamination and maintaining optical clarity.
  • Offers potential cost savings and efficiency improvements in the production of optical elements.


Original Abstract Submitted

a method for manufacturing an optical element such as a micro-optic lens may include providing a substrate having a surface profile, the substrate surface profile defining one or more flow stop features. the method may include providing a mold tool having a mold surface profile and dispensing viscous material. when the mold surface profile and the substrate surface profile are disposed towards one another and aligned relative to one another, the mold surface profile and the substrate surface profile define therebetween an optical element cavity, a peripheral cavity disposed around a periphery of the optical element cavity where the peripheral cavity includes one or more flow stop features, and an air flow path for air to flow in and out of the peripheral cavity from and to an external environment. the optical element cavity and the peripheral cavity define a peripheral constriction therebetween.
