Abstract
Systems and methods for focusing optics are disclosed herein. In some embodiments, methods are disclosed for focusing an optical device, wherein the methods can include: collecting light from a region of an object to be imaged with an objective lens, said region having a feature with a known geometric characteristic; splitting the collected light into a first portion and a second portion, and directing said first portion through a weak cylindrical lens to a focusing sensor, and directing said second portion to an imager; observing, with said focusing sensor, a shape of the feature; focusing the optical device by moving at least one of the objective lens and the object to be imaged until the observed shape of the feature has a predetermined relationship to the known geometric characteristic. In some embodiments, the feature can be a fluorescent bead. In some embodiments, the splitting step can be accomplished with a dichroic mirror. In other embodiments, the splitting step can be accomplished with a partial mirror. In some embodiments, the known geometric characteristic of the feature can be substantially spherical, the observed shape can be an oval, and the predetermined relationsh…
