- 1. Drop a small amount of PDMS onto the slide.
- 2. Bake at 70 degrees Celsius to harden it and create a base.
- 3. Afterwards, drop another dollop of PDMS onto the base and flip the slide over.
- 4. Watch as gravity pulls the new droplet down into a parabolic shape.
- 5. Bake the droplet again to solidify the lens.
- 6. Add more drops as needed to hone the lens shape and enhance the imaging quality of the lens.
