WebThe best way to determine the resolution of an optical system is to test it directly using MTF testing. One can purchase expensive MTF testers or pay someone to do the testing, but we like cost effective methods. Read below to learn more about MTF testing and an inexpensive testing method we’ve developed. WebFigure 1 shows an architecture such as this in schematic form. However, when measuring the MTF of high-NA microscope objectives, for example with an NA >0.70, we begin to run into two significant obstacles. First, the NA of the relay lens (consisting of the microscope objective and tube lens in Figure 1) must exceed that of the lens under test ...

The optical transfer function (OTF) of an optical system such as a camera, microscope, human eye, or projector specifies how different spatial frequencies are captured or transmitted. It is used by optical engineers to describe how the optics project light from the object or scene onto a photographic film, detector array, retina, screen, or simply the next item in the optical transmission chain. … WebThe magnitude is known as the Modulation Transfer Function (MTF) and the phase portion is known as the Phase Transfer Function (PTF). In imaging systems, the phase …
