The image above shows how to use the included screwdriver to adjust the DC offset.
Thorlabs' TIA60 Transimpedance Amplifier is designed to amplify the output signal from a photomultiplier tube (PMT), PIN photodiode, or other devices that require an amplified current to voltage signal. It offers a large operational bandwidth range from DC to 60 MHz (3 dB) and low noise output (4.8pA/√Hz @ 1 MHz). A trim pot, accessible through a hole in the top of the amplifier (see image to the right), provides a DC offset adjustment to improve the dynamic range of the data collection system.
The TIA60 can be powered by the KPS101 Power Supply Unit (sold below). Internal electronics of the TIA60 regulate the power to the amplification circuitry, isolating the performance of this amplifier from electrical noise that may be inherent to the power source.
The compact amplifier housing is designed to be mounted close to the detector in order to reduce the noise coupled into the unamplified signal between the detector and the amplifier. It comes with an SMA to BNC adapter, a 4-pin to power jack adapter, and a trim pot adjuster. M3 screws are also included for mounting the amplifier to the Hamamatsu H7422 series PMT.
This amplifier is fully compatible with Hamamatsu's H7422, H10720, and H10721 series PMTs, but the mounting hole pattern will only accommodate the H7422 series. The TIA60 amplifier is also compatible with our biased photodetectors and passive electrical filters.

Please note that the TIA60 does not ship with a power supply. A compatible power supply is our KPS101, sold below.
The KPS101 Power Supply Unit supports a single TIA60 Transimpedance Amplifier. It is connected to the TIA60 using the 4-pin to power jack adapter that is included with the TIA60. A location-specific adapter plug is shipped with the KPS101 based on your location.
