Abstract
A microscopic lens, of size approximately 1 micron is used for its optical characteristics.
Claims12
An optical device comprising:
- a spherical lensing element having a diameter of 10 μm or less, the spherical lensing element configured to collimate incident light to generate a collimated light beam;
- and an optical imaging element receiving the collimated light beam,
- wherein the incident light is generated by a source element having a diameter of 10 μm or less that is in physical contact with the spherical lensing element, the diameter of the source element is smaller than the diameter of the of the lensing element.
A method of focusing light comprising:
- collimating incident light with a spherical lensing element having a diameter of 10 μm or less, and
- generating the incident light from a source element having a diameter of 10 μm or less in physical contact with the spherical lensing element, the diameter of the source element is smaller than the diameter of the lensing element.
A method of focusing light comprising collimating incident light with a spherical lensing element having a diameter of 10 μm or less, and
- detecting an amplitude of the collimated light.
