we know diffraction.

Since its founding in 1967, Proto Mfg. has been developing cutting-edge instrumentation for the characterization of materials. Our product line includes various x-ray diffraction (XRD) instruments: residual stress and retained austenite measurement systems, powder diffractometers, Laue single-crystal orientation systems, and high-resolution diffractometers. In addition, we supply x-ray tubes and custom equipment to meet customers’ unique needs. For over 30 years, we have been providing effective measurement systems for laboratory, factory, and field environments. Our trained specialists also offer measurement services in our American and Canadian laboratory locations, which are ISO/IEC 17025:2017 accredited.

Residual Stress and Retained Austenite

We offer an extensive range of residual stress XRD products to provide the most suitable equipment for your measurement needs. Choose from our high-speed LXRD Laboratory system, flexible iXRD® Portable system, lightweight iXRD Mini system, innovative roboXRD system, or versatile mXRD® Ultra-Portable system.

Powder Diffraction

Our high-end powder diffractometers have been developed to provide the ultimate solution for your measurement needs. Choose from our benchtop system, compact floor model, or full-featured laboratory systems. Equipped with powerful photon-counting detectors, our powder diffractometers have extremely fast data collection capabilities while producing highly accurate data. The AXRD® product line brings you years of convenience and value for even the most demanding x-ray diffraction material investigation.

Custom Diffraction

If you need a diffractometer for a highly custom application, we can develop a unique solution for your XRD needs. Our customizable products include powder diffractometers, single-crystal systems, and many more options that can assist with your applications.

Laue Single-crystal Orientation

We have a range of options for orienting single crystals. Our cost-effective Laue-COS system is ideal for orienting and cutting crystals in R&D laboratories. Alternatively, our high-speed Laue-HT systems are designed for production-level inspection environments, such as single-crystal turbine-casting facilities.

X-ray Tubes

We manufacture a wide selection of high-quality x-ray tubes in house. Our x-ray tube fabrication facility can also create custom designs for XRD, XRF, or imaging.

Measurement Services

Trust your x-ray diffraction measurement needs to our highly skilled and knowledgeable team. Our accredited laboratories have the highest quality standards and carefully follow all procedures, ensuring accurate data collection. With over 20 dedicated XRD systems, we can accommodate your laboratory and field measurement needs with fast, accurate, and efficient service.
