Quartz-crystal orientation, cutting, sorting, and testing are just what DIANO's new system does better than anyone else. This compact diffraction instrument is geared to rapid analysis of piezo-electric crystals. System features can be selected to meet the accuracy and repeatability needed for your industrial or scientific application. The DIANO A 4 9 7 6 B A / B B XRD-700 Quartz System utilizes an Xray detector to indicate peak intensities of X-ray diffraction effects from quartz oscillators. An argon-gas-filled Quartz Ionization Cham ber and its Electrometer are mounted in a cylindrical container on the high-precision piezo goniometer. X-ray intensity is read directly from a microammeter on the table-mounted Amplifier. DIANO's XRD Double-Crystal Goniometer is available for greatest accuracy and repeatability in your orientation tests. A reference crystal (monochromator) is mounted to provide its reflected beam for rediffraction from parallel planes in the work crystal. This unique feature enables exact crystal orientation to within 5-15 seconds of arc, with over 9 5 % repeatability by skilled operators. Quartz testing from four positions is quickly accomplished. The built-in 0-50° vernier scale on the quartz goniometer arm eliminates gear-train error and provides exceptionally easy direct measure ment of test angles. For critical tuning, a 2 " dia. micrometer and vacuum chuck with three-point sapphire tip backing are standard on the Double-Crystal Goniometer. Crystallographic studies now can be faster, simpler, and more accurate with this new performer from DIANO. See your nearby DIANO representative for more details, or write:
