The QL01:
Quantum Limited Photodetection at 25nA in 1MHz

From The Designer

The QL01-A/B are the first of a family of advanced photoreceivers from Hobbs ElectroOptics. Offering a previously unattainable combination of low noise and high speed, they allow measurements at the quantum (shot noise) sensitivity limit in a full 1 MHz bandwidth at light levels from as low as 35 nanowatts up to a few microwatts. The QL01s are all-new designs based on expertise gained through our own research and from designing dozens of advanced instruments for our consulting clients.
