    Magnification Maximum
Click For Summary
SUMMARY

The maximum magnification of an object is fundamentally limited by the dispersion of emitted or reflected photons, which affects the image's signal-to-noise ratio (SNR). As the size of the object increases, the SNR decreases due to the spreading of photons over a larger surface area. While there is no theoretical limit to detection through time-exposures, the likelihood of detection errors escalates with diminishing SNR. Understanding these relationships is crucial for optimizing image clarity in magnification processes.

Assuming an object is emitting/reflecting a finite number of photons, then, there is a magnification procedure that will magnify the image of that object so much that the emitted photons will be so dispersed that the image will become unrecognizable. Do we know what this maximum is? How does it vary with respect to the size of the object? Linearly?

As you spread the reflected photons over a larger surface, the image's signal-to-noise ratio (SNR) goes down. There is no theoretical limit at which proper detection can be done, particularly when you consider taking time-exposures of the image, but the probability of detection errors varies with the SNR.
