  • Temperature: 0 °C to +40 °C
  • Storage: -10 °C to +50 °C
  • Humidity: 30% to 80% operating (non-condensing), up to 90% storage (non-condensing).

Key Features:

  • Photon Number Resolving (PNR) output capable of counting photoelectrons through ultralow noise (0.27 electrons rms) technology, enhancing quantitative imaging accuracy.
  • High Resolution and Speed: Surpasses conventional EM-CCD and sCMOS cameras with 9.4 MP and about 47 megapixels per second pixel rate readout.
  • Back-Illuminated Sensor with Trench Technology: Combines high quantum efficiency with reduced pixel crosstalk, preserving spatial resolution.
  • Applications: Quantum technology (neutral atom and ion trap experiments), astronomy (lucky imaging), Raman spectroscopy, and plant delayed fluorescence measurements.

This camera is designed for advanced scientific research requiring precise, ultra-low noise imaging and quantitative photon counting with high resolution and readout speed.

Why Questpair exists

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.

We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.

We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
