Note:

• Our 511 silicon supply has become exhausted. We regretfully can not continue to manufacture these slides.
• Quartz and silicon plates can be supplied unmounted in any rectangular or circular size up to 50 mm. These plates may be used directly or mounted by the customer in their own specimen holders. Larger sizes are possible, but they are only necessary in special diffractometer arrangements. Users should supply desired dimensions with tolerances. It is recommended that the requestor supply one specimen holder if the unmounted plates are to by used as inserts. The manufacturer and model of equipment is useful information when ordering plates without supplying a holder for size.
