  • Advanced Back-Illuminated CMOS Provides an Alternative to EMCCDs for Dynamic, Faint Astronomy

    Ground-based optical astronomy investigates various objects in space, from galaxies to exoplanets, via visible light. Some of these objects are dynamic and move at high speed through the sky.

  • Sensor Improvements to Enhance UV Sensitivity from 10 – 400 nm

    Ultraviolet light spans over the wavelength range of 10-400 nm. It is used for many different applications, from material analysis to plasma diagnostics, with different sections of the wavelength range providing different application solutions.

  • Silicon-based CCDs: The basics

    A CCD is an imaging device that detects photons, converts them into photoelectrons and moves electrical charge. They are comprised of a silicon surface onto which an integrated circuit is etched.

  • Deep Penetration In Vivo Imaging in NIR-II

    Prof. Fan Zhang’s research group, from Fudan University, is centred around in vivo­ fluorescence and biomedical imaging that cannot be detected using traditional fluorophores emitting over the visible wavelength range. His team focuses on creating and characterizing fluorescent probes to detect human disease, as well as imaging approaches to optimize fluorescent probe detection.

  • Automating Acquisition with MATLAB® as Camera Temperature Changes

    Before certain experiments, it is useful to take a series of measurements while key acquisition parameters change. The resultant data can then be utilized to optimize acquisition conditions.

  • Teledyne e2v launches new OctoPlus line scan cameras for Optical Coherence Tomography

    Teledyne e2v, the global innovator of imaging solutions, has developed a new range of line scan cameras for Optical Coherence Tomography (OCT) applications in healthcare and industrial markets.

  • Introduction to X-ray Diffraction

    X—ray diffraction is a non-destructive technique that utilizes elastic scattering to determine atomic structural information about crystalline samples. It requires high energy hard x-rays, as they have an extremely small wavelength, to discern details on the atomic level.

  • eXcelon® Technology – Novel, Performance Enhancing CCD Technology

    Since their invention in 1969, charge-coupled devices (CCDs) have been used to detect the faint light from items as nearby as cells under a microscope to those as far away as stellar objects at the edge of the known universe.

  • Full Well Capacity and Pixel Saturation

    Full well capacity is defined as the amount of charge that can be stored within an individual pixel without the pixel becoming saturated. It is dependent on the pixel size of the sensor and the camera operating voltages.

  • Cooling in Large-Area CMOS

    In Scientific Imaging, we are met with unique challenges. Signals from our imaging subject can often be very weak. With the move to CMOS technology, Quantum Efficiency, Read Noise and Dynamic Range are all optimized to work with weak signals.

  • emICCD Cameras Facilitate Use of Trapped Ions for Quantum Research

    Laser-cooled ions in linear Paul traps are quantum systems with remarkable properties. Trapped ions offer an unprecedented degree of preparation and control of their parameters, can be cooled to the ground state, and can be coupled to engineered reservoirs.

  • Improving the Collection Efficiency of Raman Spectroscopy

    Laser Raman spectroscopy is a powerful technology that is successfully used in a variety of scientific research and industrial applications. The cross-section afforded by Raman scattering is typically orders of magnitude lower than that of other optical spectroscopic methods (such as infrared absorption, laser-induced fluorescence, and ultraviolet-visible absorption), which in many cases serves to limit its utility.
