Relative SNR—How does your camera compare?

Compare microscope cameras or understand how specs affect performance.

How many photons do I have?

Find out how to measure how many photons are present under your experimental conditions.

Calculating SNR

Understand the different components that go into calculating the signal-to-noise ratio (SNR).

A visual guide to CCD vs. EM-CCD vs. CMOS

Different chip architectures, different capabilities.

Contrast versus noise, eye versus machine.

Contrast appears good, but good looks can be deceiving.
