Detection Beyond The Visible Typical Application Andor’s high energy camera solutions cover a broad wavelength range, spanning VUV, EUV, X-Ray and gamma regions. Detection is achieved either through direct detection of the high energy photon by the sensor or by indirect detection of visible photons emitted from a phosphor or scintillator, either a fiber-optic or a lens coupled to the detector. Soft X-Ray Imaging / Microscopy Soft to Hard X-Ray X-Ray Spectroscopy (e.g. SAXA), Plasma Diagnostics Hard X-Ray Diffraction / Crystallography, Phase Contrast Imaging Hard X-Ray to Gamma Gamma...

High Energy Detection The two main methods of detecting high energy photons with scientific cameras are ‘Direct’ and ‘Indirect’ detection. Direct Detection Indirect Detection Andor employs the notation ‘S’ to indicate cameras that are optimal for detection of ‘soft’ lower energy photons. With direct detection, the incident VUV to soft X-Ray photon is absorbed directly within the silicon of the sensor resulting in the production of multiple electron-hole pairs. This method of detection limits the range of usage of the sensor to photon energies that silicon can absorb directly, as shown in...

The Interfaces Andor has a comprehensive portfolio of imaging and spectroscopic camera platforms developed for use in a wide range of high energy applications. To suit these many different requirements it is often necessary to modify the camera’s interface to allow optimal integration with the sampling environment. The large area X-Ray Andor CCD system has been used to acquire much more data on each shot, enabling researchers using the Central Laser Facilities to make significantly faster progress than previously possible. This section highlights Andor’s dedicated range of interface types...

Interface - ‘Open Front’ design Interface - ‘Fiber-Optic’ design Andor’s ’O’ interface type describes an open front design, coupling directly onto a vacuum chamber’s port, ensuring maximum detection efficiency and spatial resolution. A number of Andor’s camera platforms can be configured with the ‘F’ type protruding fiberoptic interface, ideal for indirect detection of high energy X-Ray or gamma photons that are incident on a phosphor or scintillator. ‘Open front’ cameras are designed to be coupled to the outside of a vacuum chamber. There are two types of sealing options available: knife...

Interface - ‘Stand Alone’ design Andor’s ‘Y’ style interface is available across the iKon and Newton CCD camera platforms, and is built with a window that blocks visible wavelengths but allows higher energy photons through to the sensor. It is ideal for direct detection in the soft X-Ray energy range or, with inclusion of a phosphor coated fiber-optic, for indirect detection of hard X-Ray photons. Description Compact sCMOS platform, multi megapixel array, lownoise, ultra fast frame rates and high resolution imaging. High performance CCD camera with variable readout rates up to 3 MHz through...

Extending Andor’s ‘Standard’ Cameras For High Energy Detection Standard Ultra Sensitive Cameras For Lens Coupled Indirect Detection Many applications require use of lens based cameras within indirect detection systems, where a ‘stand alone’ camera solution images a scintillator screen. Such applications include both X-Ray and Neutron Tomography. Extending to the ‘UV’ Andor’s standard range of ultra-sensitive imaging and spectroscopy camera platforms can be readily customized with a MgF2 window, extending detection in the UV down to ~120 nm. Note, Features the system performance is also...
