Features

  • Transimpedance Gain: 30 200 V/A
  • Large Operation Bandwidth: DC to 60 MHz
  • Low Input Current Noise: 4.8 pA/√Hz @ 1 MHz
  • Designed for Multiphoton and Other Laser Scanning Microscopies
  • Ideal for Hamamatsu H7422, H10720, and H10721 Series PMTs

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.

  • Bandwidth and equivalent input current noise are typical values, which depend on the source capacitance. Keep the source capacitance as low as possible by using short cables at the input to achieve best possible bandwidth and noise performance.
  • Positive Gain. Current is considered positive flowing into the amplifier input, and produces a resulting positive output voltage.
  • A significant chance of damaging the amplifier exists if operating above this specification.

Hi, we are attempting to use the TIA60 together with a Hamamatsu H10770PA-40 PMT, is this trans-impedence amplifier compatible the PMT as we are struggling to get it working? Many thanks, Joseph

Hello, Joseph. Thank you for contacting Thorlabs. While I don't have a Hamamatsu H10770PA-40 on hand to test, I see that the max output current is about 2uA, only a little less than PMTSS. I will reach out to you directly to troubleshoot.

We are using the TIA60 together with the Thorlabs PMTSS PMT. (We are connecting the PMT to the amplifier with the supplied BNC to SMA cable and driving them from the same 15V source.) It seems that this combination results in an excessive noise level. Already at very low PMT gain and light levels the amplifier is completely saturated and/or there is excessive number of voltage spikes in the signal. (We have tested the PMT and TIA60 separately and they function as expected). Is there a problem specific to this amplifier/PMT combination?

Response from Bweh at Thorlabs USA: You can in principle use these together as the KPS101 that is used for the TIA60 should have enough power if proper wiring is done, which may not be the case with your setup now. We can actually provide a special version of the PMTSS with the amplifier and power supply integrated that should give you the desired performance. Or you may test using a separate power supply for the PMTSS. I will follow-up with you.

I have a number of biased Si photodiodes e.g. DET100A DET10A and was wondering on the compatibility of this amplifier (TIA60) with them to boost their output when observing low power beams and scatterred light that is modulated at high frequency (close to MHz). I am aware of the PDA200C for photodiodes but I wish to sample beyond 1 MHz if possible to avoid undersampling the signals.

Response from Jeremy at Thorlabs: The TIA60 can be used with the DET series detector. Please make sure the cable between them is as short as possible (one short SMA to BNC cable is included with the TIA60).
