ABSTRACT
This chapter first provides a brief review of the physics involved in microlenses, particularly, optics. Refractive index, absorption, and reflectance of materials are dependent on the wavelength of light and are discussed. The relationship between lens parameters such as resolution, field of view, focal length, aberrations, depth of focus, image quality, and designs are also discussed. The chapter continues with a review of surface tension because most microlenses involve the liquid-liquid or air-liquid interfaces at some point.
