Our PRODUCTS

Electrons

TEM: CheeTah

An ultra-fast, event-based electron detector for transmission electron microscopy (TEM). Its data-driven mode, and noise-free readout enables up to 1000x faster acquisition with far smaller datasets, supporting 4D-STEM, ptychography, time-resolved EELS, and ultrafast TEM with nanosecond timing and low-dose sensitivity.

Electrons

SEM: FeliS

A hybrid pixel detector for scanning electron microscopy (SEM). It mounts inside the SEM chamber and enables 3D electron diffraction (3D-ED) and 4D-STEM, bringing crystal-structure determination and orientation mapping of electron-transparent samples to nanometer-scale resolution while keeping all SEM functions available.

Photons

Phoebe

A Timepix3- or Timepix4-based single-photon camera for time-resolved imaging and photon-correlation experiments. In event-driven mode it time-stamps individual photons with sub-nanosecond precision when coupled to an optical intensifier.

Neutrons

Lumina

A fully integrated scientific image intensifier that mounts in front of your existing CCD or scientific CMOS camera, adding single-photon sensitivity, nanosecond-scale gating, and cooled dark-count suppression without replacing your camera or optical path.

Neutrons

Telesto | LumaCam

A single-photon-sensitive optical detection system for neutron science. A 256x256 or 512x512 pixel array reads light from neutron scintillators and time-stamps events for neutron imaging, tomography, Bragg-edge, and reflectometry methods.

X-ray

LynX

A hybrid pixel X-ray detector platform for diffraction, imaging, spectroscopy, and time-resolved experiments. With 55 µm pixels, event-driven photon counting, and a choice of Si, GaAs:Cr, or CdTe sensors, it delivers high-throughput X-ray detection across synchrotron, laboratory, and industrial settings.

Ions & Photoelectrons

Hyperion

An event-driven ion and electron imaging detector for velocity-map imaging, mass spectrometry, and time-of-flight experiments. It captures particle arrival time, position, and intensity at once, with multi-hit capability and no dead time between hits.

What do you want to do?
‍
At ASI, this question guides how we work. It shapes everything from sensor design and system integration to the software that transforms complex detector data into meaningful insight. Because no two experiments are the same, we believe no two solutions should be either.

R&D is embedded in our daily work. We work closely with researchers and institutions as a development partner rather than a traditional supplier, helping to enable new techniques and new ways of measuring physical phenomena.

We do not restrict ourselves to predefined applications. If advanced detection can make a difference, we are interested.

Whether you are facing a specific integration challenge, exploring a non-standard configuration, or developing a new experimental idea, we are open to working it out together.

Direct Detection and Particle Counting Principle

When a particle (such as a photon, electron, X-ray, or ion) hits the sensor surface of a Timepix3 or Medipix3 chip, it generates a charge cloud of electron-hole pairs. Due to the polarisation bias voltage, these pairs are collected at the bump-bond junction (the pixel contact). The analogue electronics then record the charge and convert it into a digital signal.
‍
With the Timepix3 chip, a threshold can be applied just above the electronic noise level, effectively eliminating all intrinsic noise in the detector. This is possible due to the high amplification of the sensor and it results in noise-free detection, where only particle hits are registered, making the chip completely data-driven.
‍
Medipix3 chips can have up to 8 different thresholds defined, allowing users to perform energy-resolved detection (e.g., for X-rays or gamma radiation).

TESTIMONIALS

"In TPX3CAM, all individual pixels function independently and are able to timestamp incident 'events'. This transforms the imaging sensor into an array of fast digitizers with both spatial and temporal resolution acting in parallel, so multiple ion species can be registered simultaneously, allowing for coincidence and covariance analyses."

"Hybrid Pixel Detectors: Boost the power of electron Diffraction!"

Prof. Dr. Jan Pieter Abrahams

Biozentrum, University of Basel

"The CheeTah Medipix3 detector, combined with continuous rotation electron diffraction, greatly improved the data quality and shortened the data collection time from hours to minutes. Ab initio structure determination by electron diffraction has now become as feasible as by X-ray diffraction but from crystals thousands of times smaller than what are needed for XRD."
