For optimum results, your TEM and synchrotron research needs reliable, high-performance, easy-to-use direct detection and readout solutions.

Filter by:



The V2F100 allows users to perform high resolution frequency to voltage conversion, a technique widely used in synchrotrons and other scientific applications.

Quantum C100

Quantum C100

QD introduces the Quantum C100. Born from discussions in the Cryo-EM field. This detector is designed as the ideal detector for performance at 100keV.



The MerlinEM Direct Electron Detector (DED), a pixelated detector ideal for applications such as 4D STEM and TEM dynamic imaging, offers rapid readout and improved signal to noise.



HEXITEC detector is a self-contained system that measures the energy and position of every incident photon in the 4-200 keV range.



Zebra, a digital signal level converter and position capture unit. Signals from multiple single channel inputs in TTL, LVDS, PECL, NIM or Open Collector format, are converted to LVTTL and passes the signals to an FPGA.

Xspress 3

Xspress 3

The Xspress 3 family of readouts has revolutionised the analysis of fluorescence detector data. Improvements in throughput and resolution optimisation, allow faster experiments with improved results.



The MerlinX photon counting detector system utilises a Medipix3 ASIC. MerlinX is packing a lot in for its size. With a vast range of applications, MerlinX is a high performance X-Ray imaging detector.

BREXIT: how does it affect shipping products to our customers?

Unfortunately, the impact of BREXIT means shipment of goods will take more time and more paperwork. However, besides this, the cost of goods should remain the same as if purchasing within the EU.

Outbound goods

  • More detailed shipping paperwork will be provided at the point of shipment by QD
    • Invoices will always detail the Harmonised Commodity codes for the products we are shipping
      • It is this HC code that dictates the tariff that the goods trigger when they are entered into the customers country
      • Our product HC codes are listed below:
        V2F100 9030333090 90303330
        Xspress3 9030820000 90308200
        X3M 9030820000 90308200
        Merlin (see note)* 9030100000 90301000
        Merlin accessories e.g. metalwork, VHDCI cables 9030900000 90309000
        Zebra 9030893000 90308930
        PandA 9030333090 90303330
        Hexitec 9030100000 90301000

        *N.B. – any Merlins being exported from the US (e.g. loan items being returned) must be marked EAR99 to indicate that no license or license exception is required; the UK equivalent is “UK Not Controlled”

  • Under WTO tariffs, our products do not attract import tax when they are brought into foreign counties (or if we have to bring them back into the UK for any reason)
  • Our Invoices will be more detailed, to help with clearance. This will include country of origin info and a more substantial description.
  • Our invoices will be electronically submitted to DHL when we make a shipment so that the courier has all the info needed to clear the goods into the receiver’s country to hand.
  • As they would when buying from any country outside the EU, the entry is smoother if the buyer nominates a customs broker to work on the import
    • This info should be provided on the PO when purchasing from QD (if not it should be secured before shipment)
    • A person of contact in the customer’s procurement team should also be provided, as the customs broker often needs to liaise with the receiver about the entry
    • QD will detail your customs broker detail on the shipping paperwork
    • QD will email your customs broker and POC with the relevant shipping info when we dispatch goods
