With a quantum-limited photoreceiver, the signal-to-noise ratio of the measurement is just that of the light itself – all the information present in your optical signal is preserved for the measurement. Typically we’re working pretty hard to get that signal, so it’s a shame to let a poor photoreceiver degrade it. That’s where the QL01 comes in.

Competing products may reach this level near DC, but none beyond 10 kHz, a full factor of 100 slower than the QL01.
Why should you care about speed? First of all, with 100 times the bandwidth and the same noise level, you get 100 times more data. More subtly, you can do your measurement further from DC, where many sources of noise and interference are much less troublesome.
