Signal-to-noise Ratio it the ratio between the actual image (signal) and noise like shot noise, scintillation and MCP induced noise.
Typical specs are:
- Gen 2 (introduction of the MCP)[1]
- SNR ~11
- Gain 3.5k to 10k
- Gen 2+[2]
- SNR <30
- Gain 10k to 60k
- Advanced Gen 2+[3]
- SNR <40
A very noisy and possibly dim image can be one sign of a end of life conditions if it can be assumed the factory specifications were considerably higher than what is observerd.
