IntroductionPerkinElmer’s new Gigahertz Photon Detection module (GPDM) provides ultra-low-light level detection in DC mode. The DC mode of operation with single photon sensitivity makes the GPDM module superior to traditional counting circuits with their high light level performance limitation. The GPDM offers the world’s highest dynamic range between 1 cps and 1 Gcps in a single operating mode, coupled with extremely low noise performance.

The fully-equipped module includes the Channel Photomultiplier, the high voltage supply, analogue current amplifier, A to D conversion, and a microcontroller with USB/SPI interface, allowing for adapting to a wide range of applications. Additional features like the synchronization I/O offer the ability to synchronize the measurement with other devices, such as flash lamp trigger.

Notes:

1) See below performance characteristics

2) CPM characteristics can be matched to the application’s requirements – see spectral response curve

3) Gain pre-set to optimal single photons sensitivity

4) Actual output information is RLU (relative light unit) – counts per second is the calculated value based on RLU

To enable best performance characteristics for different application depending requirements, the GPDM offers different operating modes, which can either be selected manually or will be set automatically:

Real Counting Mode

Straight Output Mode

Fast Switching Mode

HV Reduction Mode

1 CPS – 10 k CPS

1 CPS – 50 M CPS

1 CPS – 1 G CPS

– 10 G CPS

Real Counting Mode: Represents the digital information whether a photon has been detected or not. This method can be used for internal count rate – Rel. light unit calibration

Straight Output Mode: Output information in rel. light units, no internal switching required

Fast Switching Mode: Output information in rel. light units, extended dynamic range by fast Gain switching

HV Reduction Mode: HV Reduction Mode: Output information in rel. light units, extended light intensity range by manual HV reduction
