With
the completely newly developed HBPR
photoreceiver/photodetector platform, FEMTO has
raised the bar in the field of balanced
photoreceivers to a new level.
Two
photodiodes connected in anti-parallel subtract the
two input signals and feed the difference to a
subsequent low-noise transimpedance amplifier. The
extraordinarily high common mode rejection, the low
input noise and bandwidths up to 500 MHz set new
standards and enable highly sensitive signal
acquisition.
In
addition to the outstanding technical data, great
importance was attached to user-friendly details and
versatility when developing the new HBPR platform:
thanks to:
- Free space and
fiber-coupled inputs
- Switchable gain and
bandwidth
- Switchable AC/DC coupling
- Broad mechanical
compatibility with common optical accessories
the
photoreceivers of the HBPR series are among the most
versatile balanced photoreceivers/photodetectors on
the market.
Typical
applications are:
- optical spectroscopy
- coherent heterodyne
detection
- homodyne detection of
optical quantum states
- optical coherence
tomography (OCT)
- differential optical front
end for oscilloscopes
- spectrum analyzers
- A/D converters and lock-in
amplifiers
