Optical Design of a Dual Channel Microscope

The article presents a new scheme of an optical microscope. The proposed scheme contains two channels: one works with a wide field of view, the other forms a high-resolution image. The simultaneous fulfillment of these conditions significantly increases the information capacity of the system. The proposed scheme overcomes the limitations imposed by the Lagrange invariant. In addition, the presented work solves the relevant task of optical instrumentation: using one device,it becomes possible to simultaneously obtain an image of an object in two scales, one of which gives a detailed image of microstructures, and the other shows the state of the area around the part of the object being studied in detail. This time synchronization is especially important for studying biological objects. The design features of the optical scheme make it possible to abandon the refocusing of the objective, which is necessary in biological microscopes when the magnification is changed. Thus, the proposed system solves not only scientific and technical tasks, but also improves the ergonomics of work in microscopy.
