WSXC10 X-Ray Laue Camera

Application:

The WSXC 10 camera is designed for the orientation of single crystal samples where cutting is required along strictly determined crystallographic planes.

General Characteristics:

The WSXC10 camera is used to hold crystals in the process of determining crystallographic orientation using Laue back reflection. The diffracted beams are registered by the wet film photographic method.
WSXC10 X-Ray camera is a set consisting of : A crystal can be rotated 360o in one axis with 0.1o vernier and 120o in second axis with 0.1o vernier. The goniometer can be fixed to the WS 22 , WS 22B or WS 22C Wire Saw. The WSXC10 camera is constructed of hard stainless material. The scales are deeply engraved and filled with a black ink. The crystal is cemented to a mounting table which is the central element of the goniometer. There are precision rises available toincrease the height of the goniometer when working with crystals that are too small to reach the beam. If the face of the crystal is rotated to a position that is not in the path of the x-ray or optical beam, the table can be moved up to 10 mm on either side of center in order to realign the crystal with the x-ray or optical beam. After the crystal is properly oriented, the whole goniometer is transferred to a saw for cutting the oriented surfaces or slices.

WSXC 20 Optical Orientation Device

The WSXC 20 Optical Orientation Device is used to determine the orientation of a crystal or to align a crystal so the specifically oriented surface can be cut. The model WSXC20 uses a laser beam reflected from a cleaved or preferentialy etched crystal surface back onto a target that is perpendicular to the laser beam.
WSXC 20 optical orientation device is the set consisting of: This type of orientation can be very accurate but it depends on getting a good reflection of the laser beam. With resolution of less than beam diameter, on a distance of 50 cm between the target and the face of the crystal, it is easy to reach an accuracy of 0.02o on the goniometer. The base of the WSXC 20 optical orientation instrument is a 750 mm long optical track. A 0.5 milliwatt laser is mounted on the end of the track. Attached to the output side of the laser is a 120 mm diameter round target that has been factory adjusted to be concentric and perpendicular to the laser beam. The mount that holds the laser on the track has both horizontal and vertical adjustments that are used to position the laser beam parallel to the optical track and to the goniometer face with all settings at zero.

Technical data:

voltage 220 V or 110 V
Output 30 Watts

Short 3.5 min
Long 7 min

The DURAN ultrasonic cleaner employs ultra sound to penetrate objects of the most complicated shape, thus accomplishing exceptional cleanliness. High efficiency in an ultrasonic system is achieved by the energy generated by mechanical oscillations. High frequency (44 000 Hz) sound waves, too high pitched to be heard, cause the phenomenon of cavitation, that is creating bubbles of low pressure vapours in liquids. These bubbles remove all impurities from the least accessible parts of immersed objects. Scientific research has proven that ultrasonics improve the efficiency of desinfecting agents by a factor of four. Thanks to thermic insulation and to ultrasonic energy, while the cleaner is on, one can keep the liquid at a temperature of 50oC.

The WSXC12 X-ray Laue camera with Polaroid cassette system. The Polaroid system is used in conjunction with two axis goniometer for recording reflected Laue patterns. This device makes it easy to produce high quality, accurate, instant photographs for crystallographic analysis. The Polaroid film produces 4x5" black and white photographs in seconds.
The system consists of: An integral part of the XR-7 cassette is a special intensifying screen with a high-speed, high resolution phosphorous alows coating on its surface. During exposure the coating thereby producing a visible light pattern of the x-ray information. The emulsion side of an ultra sensitive 4x5 negative is held in tight contact with the screen by a unique air-filled pillow. This pillow exerts an even pressure over the entire picture area to assure image sharpness. The visible light pattern is recorded on the negative. After exposure the film is withdrawn from the cassette and left to develop within its protective envelope. The cassette has four reference marks on the intensifying screen. These are recorded as small, distinct, black dots in each photograph, two on the vertical axis and two on the horizontal axis. The intersection of lines drawn between these two pairs of dots locates the center of the picture. Recommended for the system is the Polaroid 3000 speed 4x5 Land film, Type 57. The combination of this highly sensitive film and the special intensifying screen makes possible significant reductions in x-ray exposure times. It also permits operation of the x-ray tube at relatively low voltages-for example, in the range of 15-25 kV with currents between 20-30 mA-with special kinds of specimens. The picture is developed within seconds, permitting immediate analysis of results and facilitating rapid determination of correct exposures. The another main element of the system is the two axis goniometer. The goniometer is equipped with a table on which theivestigated crystal can be waxed. The table height can be adjusted with two nuts on the table console. A crystal can be rotated 360o in one axis within 0.1o vernier and 120o in second axis within 0.1o vernier. After orientation, the goniometer can be transferred to either the WS 22 or the WS 22B/C high precision wire saws to cut the sample.(Goniometer can be attached to each type of Unipress wire saws).

Print size: 4x5"
Image size: 3.5x4.5"
Polaroid film type: 57 high speed fil
Speed ISO/DIN equivalents ISO 3000/36
