APPARATUS FOR DETERMINING POSITIONS OF OBJECTS CONTAINED IN A SAMPLE

摘要

The invention relates to an apparatus for determining positions of objects contained within a sample. The apparatus comprises an image sensor configured to transform incident light to image data, an optical system comprising a lens arrangement and an aperture, a light emitting device configured to generate light towards said image sensor, and an image data processor configured to receive image data from said image sensor and to determine positions for objects in said image data. The optical system is configured such that a depth of field of said optical system is larger than or equal to a thickness of said sample.
