Raman spectroscopists, when using CW lasers, often make us of long exposure times (1 sec to 20 minutes) in order to reach a resired signal to shot noise ratio, and in those instances a multi-MHz readout camera is not required. However, there are many cases where shorter exposure times must be applied, such as when following fast reactions, temperature jump experiments, and also for Raman mapping with high throughput. In these instances, the read noise floor of the sensor can contribute significantly to the overall signal- to- noise ratio. Also, there are many intances in which light levels are fundamentally or necessarily low, such as when studying photolabile molecules, or when the concentration of the probed species is low. Again, this can render the read noise floor more significant.
