Imaging systems and scientific cameras from X-ray to IR
Highly-sensitive, scientific imaging cameras based on CCD, EMCCD or sCMOS sensors from the innovator in camera technology, Andor Technology. Common features are their high-sensitivity in the UV and visible range. Thermo-electric cooling and high-quality AD converters reduce noise to allow application even in extreme low-light conditions.
For photon energies between 10 eV and 20 keV CCD sensors without micro lens arrays and anti-reflection coating are required. Direct detection of VUV, EUV and soft X-rays occurs by photon absorption and generation of electron hole pairs. Our cameras for high energy detection provide a solution for almost any energy range and experimental condition. This can be stand-alone operation, indirect detection methods using scintillator screens or vacuum compatible detectors.
Cameras and detectors for time-resolved imaging and spectroscopy have an image intensifier in front of the sensor. The image intensifier acts as an ultra-fast optical shutter for exposure times of a few nanoseconds. Because of the image intensifier’s high gain, extremely faint signals down to single photons can be detected. The series of intensified charge coupled devices, ICCD for short, is called iStar. The iStar ICCD cameras and detectors from Andor Technology are characterized by scientific grade CCD sensors, fast gate electronics and high-quality image intensifier. In addition, we offer the iZyla, an intensified sCMOS camera with a detachable image intensifier. The iZyla acquires up to 100 frames/s at 5.5 megapixel resolution.
Near infrared cameras
InGaAs cameras have the highest quantum efficiency in the NIR. NIR cameras cover the wavelength range of 900 – 1700 nm, a range that is best suited for absorption and radiation characteristics analyses. Typical NIR cameras feature either 320 x 256 or 640 x 512 pixels. You may choose between USB, analog, cameraLink, GigE or even GigE Vision interfaces.
Shortwave infrared cameras
Thermal imaging cameras in the shortwave infrared become more and more important. Typical applications can be found in photovoltaics, agricultural technology, laser beam profiling, the food industry, and the synthetics industry. Our shortwave infrared cameras cover the full range from 1000 – 2350 nm.
Spectral analyses or applications in photovoltaics demand sensitivities in the visible range and at the same time recordings in the near infrared up to 1700 nm.
Our standard InGaAs detector is combined with an InP layer. When the InP layer is etched away, the detector becomes sensitive in the visible range. Our models XS, Xeva and Cheetah may be fitted with this novel VISNIR detector. Thus equipped they can reach continuous sensitivities of 500 – 1700 nm.
Cameras in the mid infrared wavelength range 3-5 µm are already considered thermal imaging cameras, but the focus is on high-quality images rather than temperature measurements and mobility. The main detector materials in the mid infrared are InSb and MCT. Both camera systems are also offered as large format and high-speed versions. All cameras of the Onca series come with a built-in filter wheel, full trigger option, and GigE Vision, analog and CameraLink interface. Our InSb infrared cameras are also available with an enhanced spectral range of 1 – 5 µm.
The main application fields are non-destructive testing, scientific applications with a focus on high temperature resolution and frame rate, and usage as spectral camera and thermal imaging camera in surveillance.
Our longwave infrared cameras take advantage of a high-quality microbolometer camera which is combined with high performance electronics this leads to uncooled LWIR cameras with unsurpassed image quality in the market.
Although our uncooled microbolometer cameras are small and light weight their image quality is the reason that they are well known as scientific measurement systems.
Our partner Cordin is the world leader in ultra high speed imaging technology. Depending on the camera system in use frame rates up to 200 000 000 frames per second are possible. Very short integration times and inter frame times are standard. Gated and intensified models are available. Among other modules Cordin offers ultra-high speed camera systems with up to 2000 x 2000 pixel at full frame rate in colour or black and white.
Streak camera systems for scientific applications are available and developed with modern technology.

Atomic Force Microscopy (AFM) traces the topography of samples with extremely high- up to atomic- resolution by recording the interaction forces between the surface and a sharp tip mounted on a cantilever. AFM provides spatial information parallel and perpendicular to the surface. In addition to topographic high-resolution information, local material properties such as adhesion and stiffness can be investigated by analyzing tip-sample interaction forces. We offer AFMs suitable for research in materials science, polymers, electrochemistry, and other applications in nano-science and engineering.
Confocal Raman microscopy is a high-resolution imaging technique that is widely used for the characterization of materials and specimens in terms of their chemical composition. With 2D and 3D Raman images, information regarding the chemical compounds and their distribution within the sample can be illustrated clearly.
In scanning near-field optical microscopy (SNOM), the excitation laser light is focused through an aperture with a diameter smaller than the excitation wavelength, resulting in an evanescent field (or near-field) on the far side of the aperture.
A spectral camera images a line of an object and provides the spectral information of each pixel in the second dimension of the line. Corresponding software displays a 3 dimensional spectral cube of an object or displays spectral information of moving objects.
A hyperspectral camera set-up includes optics, an imaging spectrograph, a camera displaying the spectral information and a software package to display and calculate the results.
Optical radiometry is the science of light measurement, spanning across the ultraviolet, visible and infrared regions of the electromagnetic spectrum. Photometry is the subset of radiometry dedicated to the measurement of visible light as it is perceived by the average human eye.
International Light Technologies (ILT) has been the most respected name in research oriented light measurement for 40 years. They offer a variety of modular light meters. Optical radiation is perhaps the most difficult form of energy to measure accurately. Light energy is distributed over wavelength, position, direction, time and polarization.

Atomic force microscopy traces the topography of samples with extremely high resolution by recording the interaction forces between the surface and a sharp tip mounted on a cantilever.
The sample is scanned under the tip using a piezo-driven scanning-stage and the topography is displayed as an image. Atomic force microscopy provides spatial information parallel and perpendicular to the surface with resolution in the nm range. In addition to topographic high-resolution information, local material properties such as adhesion and stiffness can be investigated by analyzing the tip-sample interaction forces.
The WITec atomic force microscope (AFM) integrated into a research-grade optical microscope provides superior optical access, easy cantilever alignment and high-resolution sample survey.
ARTIDIS (automated reliable tissue diagnostic) is a new tool for automated nanomechanical tissue diagnostics and soft material analysis which provides nanomechanical investigations and their quantitative and statistical analysis. Nanomechanical measurements on suspect tissues, for example, provide a characteristic “fingerprint” that allows automatic classification into healthy tissue, benign material, or malignant tumor.
