The Fast Imaging Camera is for TomographyThese 250x200mm cameras use large CCD or CMOS detectors coupled with bright lenses. Larger or smaller cameras, with FOV from 125x100mm to 500x400mm can be custom made.

To reconstruct 3D tomographic images you can use the free MuhRec Tomography.
The slim USB CCD requires no control box or powerOur modern slim USB CCD uses 10m amplified USB cables (supplied with the camera) for power as well as 16-bit image collection and exposure control. You need a computer to display real-time images, not a TV monitor, but the slim USB CCD has much higher grey-scale resolution as well as being a little more efficient. It has the same spatial resolution and costs the same as the video CCD.
All components of the slim USB camera can be easily replaced.
To control this camera and display the image on a PC, you need special software (included with the camera).
The fast FLIR, BASLER and ZWO CMOS Cameras
All our small x-ray or neutron cameras can be supplied with an optional FLIR (Point Grey), BASLER or ZWO CMOS camera when high frame rates are required (up to 41 fps). Dark current noise is higher for CMOS cameras, limiting them to shorter exposures of up to minutes, but cooled versions with the 3000x3000 pixel IMX533 can also be provided.
The IMX174 is currently the best small Sony CMOS detector for low-light imaging. It is a relatively large sensor, with big pixels favouring light capture, with high Quantum Efficiency. The ZWO camera is powered by a USB cable, and the FLIR GigE version by a powered GigE cable.
The video CCD can be used with a monitor or a PCThis is our original neutron camera, and is still available. The advantage of the Watec video CCD is that you can display the image in real time on a simple TV monitor over an extension cable or eventually a wireless-video transmitter. The camera integrates the image over the set exposure time, but outputs a real-time video signal. The exposure is controlled by a small box via a 3-metre 16-wire cable. To record and analyse the image on a PC, a video frame grabber is needed (included with the camera). Please the the NeutronOptics Video Camera Manual.
The high resolution CCD is for long exposuresThe high resolution cooled CCD provides a choice of high resolution with a low noise CCD.

The 1-CCD Laue x-ray or neutron camera
The NeutronOptics 1-CCD Laue Camera is usually preferred to the older 2-CCD camera, since it is less expensive, simpler to operate, and usually faster, since it uses a larger CCD to image a smaller, but still sufficient area of 120x100mm.
Si backscattered Laue pattern was obtained by Dr Dean Hudek at Brown University, and a
Sm2Fe17 pattern was obtained by Dr Léopold Diop and Prof W. Donner at the Technische Universität Darmstadt in only 2 minutes on a 1960'6 Philips x-ray generator with a spot size of ~1mm and power of 30-50 kV and 30-50 mA.
To control this camera, you need special software (included).
The 2-CCD Laue x-ray or neutron camera
The NeutronOptics 2-CCD Laue Camera uses twin CCD units to increase efficiency, extend the image field, and avoid the shadow from the central collimator. The separate images are automatically stitched together using free ImageJ software to produce a
160x120mm image. To control this camera, you need special software (included).
High Resolution Macro Imaging CamerasOur standard macro camera provides 1:1 macro imaging, where the object is the same size as the CCD. The resolution of small objects is limited only by the resolution of the the latest Gd2O2S:Tb high resolution neutron/x-ray scintillators now available from RC-TriTec. It is supplied with standard x-ray and neutron scintillators that can be interchanged easily.
Any C- or F-mount detector can be used, or even an ordinary Nikon or Canon SLR camera with the appropriate adapter. A 50µ grid can be imaged with 3.9µ CCD pixels to an optical resolution of <10µ (detail), though the real resolution will depend on the scintillator and collimation.
To control this camera with one of our high resolution CCDs, you need special software (included).
High Resolution Tandem Macro CamerasOur Tandem Macro camera also provides 1:1 macro imaging, and the intensity is up to x8 greater, but over a maximum FOV of only 10mm. The resolution is again limited by the resolution of the the latest RC-TriTec Gd2O2S:Tb neutron or x-ray scintilltors. Standard OG2 x-ray and 400µ neutron scintillators are supplied and can be easily interchanged.
Any C- or F-mount detector can be used with the appropriate adapter, or even an ordinary Nikon consumer camera. This image was obtained in 3s on the ILL NeXT D50 beamline from our twin Nikkor 50mm 1:1 camera using a 10µ thick RC-TriTec Gd2O2S:Tb(LiF) scintillator with 6% of the light output of their 200µ scintillator. The inner circle shows that at least 25µ resolution was obtained.
To control this camera you need special software (included).
The Old Macro x-ray or neutron cameraOur old macro camera provided magnified images of small objects, with a resolution limited only by the resolution of the scintillator. It is supplied with standard x-ray and neutron scintillators that can be interchanged easily; high resolution scintillators must be obtained separately.
Our old Macro camera was supplied with the
cooled Mammut CCD (shown), and special software must be used with that camera. Those instructions also describe how to set up the camera, even if your camera uses instead the slim CCD or the hi-res CCD.
