Abstract

We present a telecentric design to obtain constant magnification with long axial scanning range in an optical sectioning microscope. A Moiré lens is included and utilized for this purpose. The design principles of our system are explained through mathematical expression and simulation results are provided for different conditions, which include the case of variation displacement of the focal plane with different Moiré lens focal length, and the scanning range in terms of the magnification value. Furthermore, we also use the Zemax ray-tracing simulation method to show the telecentric examples for different magnification value with corresponding Moiré lens focal length.
