  We have developed an economical dual CCD camera that can replace the traditional Polaroid Laue camera with real-time readout.

  
  

  The large aperture lens is used to image the scintillator onto the CCD, and the CCD also has a micro lens on each pixel.

  
  

  The camera is similar to the traditional Polaroid Laue camera, simple, efficient and low-cost, but the image can be used to determine the crystal orientation immediately

  
  

  NeutronOptics Laue cameras use dual CCD units to increase efficiency, expand the image field, and avoid the shadow of the central collimator.

  
  

  Use the free ImageJ software to automatically stitch together separate images to correct the relative position of each image,

  
  

  The angle and lens aberrations then produce a single 160x120mm image.

  
  

  Below is a more detailed raw Lloyd data of a highly compressed JPEG image obtained 300 seconds with

  
  

  35kV/50mA copper anode x-ray backscattered 30mm from strong absorption of Pt(111).

  
  

  Data provided by Nakkiran Arulmozhi, the laboratory of Professor Gregory Jerkiewicz, Department of Chemistry, Queen's University, Ontario, Canada.

  
  

  Touch the mouse on the image to apply imageJ's bandpass filter to emphasize peaks.

  
  

  The central collimator (not shown) collects the light beam transmitted through the crystal in forward scattering,

  
  

  Or allow the incident beam to pass through the camera before being reflected by the backscattered crystal.

  
  

  In either case, many Bragg spots are obtained from different wavelengths in the white light beam.

  
  

  When the crystal is too absorbing for forward scattering, back scattering is used, although the intensity is much lower.

  
  

  Our Laue cameras can provide scintillators, windows and collimators suitable for neutrons or X-rays.

  
  

  The photo shows an X-ray camera with dual high-resolution CCDs. The 160x120mm carbon fiber window adopts a collimating tube through its center.

  
  

  Even for CuKα X-rays (8KeV), the transmittance of the carbon window is estimated to be> 70%

  
  

  
  

  
  

  Laue Camera Build

  
  

  First read the description of the standard NeutronOptics camera, or the description of the high-resolution CCD option.

  
  

  If the Laue camera has two CCD units, and you have two power supplies and two USB connections, it is best to use different USB hubs.

  
  

  Use the 4mm bolt hole on the back to mount the camera as close to the light source as possible; minor adjustments to position and direction should be provided.

  
  

  Before inserting the collimator tube into the camera, check that it conforms to the source outlet and that there is no X-ray leakage.

  
  

  Insert the processed end from the rear of the camera first, and tighten it slightly until the x2 CCD camera protrudes from the front window.

  
  

  Do not apply lateral force because the collimator passes through the hole between the two mirrors. With an x1 CCD camera, the fixed internal collimator will not protrude from the front window.

  
  

  Carbon fiber windows and plastic scintillators are not fragile.

  
  

  The camera and collimator must be precisely aligned, and the source voltage and current are set to the maximum x-ray intensity passing through the collimator.

  
  

  Our mini i-Cam camera can be used to maximize the position of the beam and the sample,

  
  

  Otherwise, the Laue camera itself is used for image transmission through the collimator.

  
  

  If you have a single CCD camera, just follow the instructions for the high resolution CCD,

  
  

  Then jump to the index

  
  

  The typical exposure time of backscattered Laue is ?300 seconds.

  
  

  But first try a shorter exposure, without beams, to check that everything is ok-you should see background noise.
