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 You will then need special software (included with the camera).
The slim USB CCD requires no control box or powerOur modern slim USB CCD uses a single 10m USB cable (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 high Frame Rate FLIR and BASLER CMOS Cameras
All our small x-ray or neutron cameras can be supplied with an optional FLIR (Point Grey) or BASLER CMOS camera when high frame rates are required (up to 41 fps). The maximum exposure of the IMX249 camera with USB3 is only 4 seconds (30 seconds for the GigE version); dark current noise is higher for CMOS cameras, limiting them to short exposures.
The IMX249 is a slower frame-rate version of the IMX174, and currently the best Sony CMOS detector for low-light imaging. It is a relatively large sensor, with big pixels favouring light capture, with high Quantum Efficiency. The USB3 camera is powered by a USB cable, and the GigE version by a powered GigE cable.
The high resolution CCD is for more serious imagingThe high resolution cooled CCD provides a choice of high resolution with low noise, depending on the FS14 or FS60 chosen 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. This 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.
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).
The New Macro x-ray or neutron camera
High Resolution Macro Imaging CamerasOur new 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 of our high resolution CCD units can be used, or even an ordinary Nikon or Canon SLR camera. 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).
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.
