Abstract: Provided herein is a macroscope comprising an objective apparatus comprising a multifocal widefield optics comprising a plurality of optical components configured to focus on a plurality of planes. Also provided herein are methods for analyzing a three-dimensional specimen, the method comprising obtaining, via a macroscope, synchronous multifocal optical images of a plurality of planes of the three-dimensional specimen, wherein the macroscope comprises an objective apparatus comprising a multifocal widefield optics comprising a plurality of optical components configured to focus on a plurality of planes. The three-dimensional specimen can be a biological specimen, such as brain.
