RF1 Quantum Amplifier

RF1 Quantum Amplifier

A quantum amplifier is a device that amplifies the quantum noise figure of a signal. It works with geiger mode sensors or amplifies the shot noise present in other signals. It is very  useful for noise reduction or comparison of common shot noise identities in more signals, if used with a correlator.

The RF1 is a quantum amplifier with high gain and a builtin square-law high bandwidth quantum detection circuitry.
It’s suitable with the XC crosscorrelators and allows to connect to the correlator any analog sensoring device.

HSP17 Photomultiplier Assemblies

HSP17 Photomultiplier Assemblies

The HSP17 is a photomultiplier assembly, a device designed for extreme sensitivity in terms of quantum counting techniques (photons).

Photon counting is useful when measuring photon noise, as usually light is measured treating the light flux as a wave, or at larger scales as an intensity over time, photon counting measures the quantity of single light energy pulses over time, where a wave is composed by a sum and series of pulses.

Photomultipliers are the first type of photosensitive electronic device. It offers high sensitivity  in UV rays, and its spectral response can reach VIS to IR in some cases. Its very fast light variance response make it a nice choice for high speed photometry, optical intensity interferometry, spectrometry and time-of-arrival photon statistical applications.

The HSP17 offers various sensibility and spectral response sensors. The enclosure in aluminium can house a thermal cooler or specific adaptive optics and contains the sensor, the power supply and the readout circuitry. The front optical entrance has a C-type thread.
The supply and readout connector is compatible with the XC series cross-correlators and power supply and pulse readout are made by using a single cable.
