Quantum Limited Photoreceiver QL01-B
Description
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. We also do specials and other OEM products, so if you have an unusual requirement, give us a call or send an email.

Frequently Asked Questions
The QL01-A/B photoreceivers have a full 1 MHz bandwidth.
The QL01-A/B can measure light levels as low as 35 nanowatts.
The QL01-A/B achieves its outstanding performance through a proprietary bootstrap topology that reduces the effect of photodiode capacitance by a factor of over 1000, with sub-nanovolt noise densities.
The QL01-A model offers a 7x increase in detector area for more light collection and ease of alignment, while the QL01-B model provides shot-noise-limited detection performance at its full 1 MHz bandwidth.
The QL01 can be used in low-light applications in solid state physics, spectroscopy, chemistry, biology, and other fields.
