Trigger Diode Assembly |
TDA 200 |
 |
| |
As an accessory for the PicoQuant Systems or the TCSPC devices, PicoQuant offers a trigger diode assembly for use with free running laser systems. It contains a high speed Si pin-photodiode, short focus collimation lens, integrated filter holder and threads for a mounting post. The range for optical wavelength is from 350 to 1100 nm with a maximum sensitivity at 800 nm. A multicolor LED allows to adjust the light level suitable e.g. for the TimeHarp series input. Color and brightness are responding to the energy of the input pulses and therefore provide an easy to use adjustment tool. The required 12V DC power supply is shipped with the product. |

Pre-Amplifier Module |
PAM 102 |
|
| |
The PAM 102 pre-amplifier is specially targeted at timing sensitive applications such as Time-Correlated Single Photon Counting (TCSPC) with fast photon detectors like Microchannel plate PMTs or standard PMTs. It offers an amplification of 25 dB (optionally 20 dB) up to a frequency of 1.8 GHz. The bandwidth is optimized for minimum timing jitter at typical detector pulse rise times. Different modules are available for MCP-PMTs, PMTs or solid state detectors. The required 12V DC power supply is shipped with the product. |

LTT 100 Sync. Adaptor |
LTT 100 |
|
| |
As an accessory for PicoQuant TimeHarp series TCSPC-board the LTT 100 adapter is offered. It is designed to optimize the synchronization output from the PDL 800-B for use with the TimeHarp series. The signal is differentiated and transformed into a short pulse optimally suited for the TimeHarp boards. The LTT 100 will be supplied with PicoQuant systems and the TimeHarp 200, but needs to be ordered separately when individual components are purchased. |

SMA Inline Attenuators |
ATM 20 / 10 / 5 |
|
| |
The ATM series attenuators are used to attenuate signals from e.g. Single Photon Avalanche Diode (SPAD) modules. The higher signal amplitude of the TTL pulses from these detectors exceeds the input voltage range for e.g. the TimeHarp 200. Typically a 20 dB attenuator unit is used to connect a SPCM-AQR(H) SPAD to a TimeHarp 200 TCSPC-board. Available from PicoQuant are attenuators with 5, 10 and 20 dB. |

Inverter and Attenuator Module |
SIA 400 |
|
| |
The SIA 400 module is a passive module designed to invert and attenuate (20dB) TTL pulses produced e.g. by Single Photon Avalanche Diode (SPAD) modules to negative pulses compatible with TCSPC electronics such as the TimeHarp 200 PC-board or the PicoHarp 300 module. It can also be used as a sync. inverter for the TimeHarp 200. The SIA 400 has BNC connectors at both ends. |

Power Splitter Module |
PSM 50 |
|
| |
The PSM 50 power splitter (reflection free T-pad) allows a 50 Ohms RF source to feed two 50 Ohms loads simultaneously. This task cannot be performed by an ordinary T-pad without severe reflections and consequent signal distortion. This is particularly important in timing sensitive applications such as TCSPC. Max. power dissipation 0.2 W. |

Cables |
Cables |
|
| |
PicoQuant can offer a range of special made signal cables with SMA or BNC connectors as well as delay cables with Lemo connectors for the PDL 808 "Sepia" laser drivers. For signal connections we recommend RG 223 cable. This cable type has a double braided silver plated screen which provides optimum shielding in timing sensitive applications such as TCSPC. |
