For ultra-fast crystal orientation measurement using the Omega-scan method

The Desktop X-ray Diffractometer for Crystal Orientation Measurement (DDCOM) is an automated tool to determine the orientation of various crystals using the Omega-scan method.

Ultra-fast Omega-scan approach

  • 200 times faster than Theta-scan method

  • Automatic evaluation of the complete lattice orientation in 3D

  • Determination of entire crystal orientation within 5 seconds

Compact, user friendly and cost effective

  • Easily movable and lightweight desktop design

  • Convenient sample handling and easy to operate

  • Low energy consumption and operating costs due to air cooled X-ray tube (no water cooling required)

Efficient workflows for quality control

  • For standard research and industrial workflows

  • Azimuthal setting and marking of crystal orientation

  • Preprogrammed cubic crystal parameters

  • State-of-the-art and convenient software

  • High precision, i.e up to (1/100)°

Control of cutting, grinding and lapping

  • Complete lattice orientation of single crystals

  • Suitable for a unique variety of materials in a large range of size and weight, such as: Wafers from 2-12” and Ingots up to 20kg


  • Determination of the complete lattice orientation of single crystals

  • Ultra-fast crystal orientation measurement using the Omega-scan method

  • Determination of the arbitrary unknown orientation of cubic crystals

  • Designed especially for azimuthal setting and marking of lattice directions

  • Air cooled X-ray tube, no water cooling required

  • Appropriate for research and production quality control
