  • Understanding Read Noise in sCMOS Cameras (Beitrag von Andor Technology)

    sCMOS based cameras can provide a much lower noise floor than typical CCD based cameras. A low noise floor means that the camera can detect signals that would otherwise have remained hidden within the noise background which helps to produce a high-fidelity image. A low noise floor also allows for the widest possible dynamic range. One of the main types of noise that makes up this noise floor comes from “Read Noise”. What is Read Noise? What factors affect Read Noise?   Read here more about Readout Noise in sCMOS Sensors on Andor Technology's website

  • The History and Development of sCMOS (Beitrag von Andor Technology)

    sCMOS cameras are now the most common type of camera technology used for scientific imaging. Read the interview with Dr. Colin Coates who has been involved in the development of sCMOS cameras at Andor Technology, how and why these cameras have come to be so popular.

  • Fallstudie: Experiment mit einer ANDOR Marana Kamera an einem High End Amateurteleskop auf La Palma

    Ein erstes Experiment mit einer ANDOR Kamera an einem High End Amateurteleskop erfolgte im Juli 2020 auf La Palma, in Zusammenarbeit mit dem bekannten Astrofotografen Christoph Kaltseis. Dabei hat sich herausgestellt, dass durch die Empfindlichkeit und das saubere Signal der ANDOR Kameras mit deutlich reduziertem Zeitaufwand hervorragende Aufnahmen gewonnen werden können. Sicherlich ist das Potential der ANDOR Marana bei diesem Test nur ansatzweise genutzt worden. Findige Amateure werden in Zukunft das Zusammenspiel von kleineren Teleskopen und ANDOR Kameras noch weiter erkunden und bisher unerreichte Ergebnisse erzielen. Mehr dazu auf Andor Technology

  • What is an Electron Multiplying CCD (EMCCD) Camera? (Beitrag von Andor Technolgy)

    EMCCD technology, sometimes known as ‘on-chip multiplication’, is an innovation first introduced to the digital scientific imaging community by Andor Technology in 2001, with the launch of our dedicated, high-end iXon EMCCD Camera platform of ultra-sensitive cameras. Essentially, the EMCCD is an image sensor that is capable of detecting single photon events without an image intensifier, achievable by way of a unique electron multiplying structure built into the chip.

  • EMCCD vs sCMOS Cameras | A Comparison (Beitrag von Andor Technology)

    sCMOS technology is unique in its ability to overcome many of the mutual exclusivities that have marred other scientific detector technologies, resulting in an imaging detector that simultaneously optimizes a range of important performance parameters whilst maintaining Snapshot exposure capability.

  • Webinar – Impact of EMCCDs on Speckle Imaging (Beitrag von Andor Technology)

    Speckle imaging produces diffraction-limited images from ground-based telescopes in the optical wavebands. While the technique dates back almost 50 years, recent advancements in detectors such as electron-multiplying CCDs (EMCCDs) have spawned a resurgence of this technique. The use of EMCCDs has greatly improved sensitivity and observing efficiency for speckle instruments. The high angular resolution provided by speckle imaging can discern blended binary system contamination and validate suspected exoplanets discovered by the Kepler, K2, and TESS transit surveys. Three speckle instruments have been built to this purpose: one at the WIYN telescope, one at Gemini-North, and one at Gemini-South. These instruments are supported by NASA's Exoplanet Program Office and available for the community via the proposal process for each telescope. Multiplicity can be determined along with...
