Diffractive optics Inprentus manufactures blazed, x-ray diffraction gratings using a new nano-scale contact mode lithography technique that can scribe thousands of lines per millimeter, providing the ultra-accuracy required for diffraction gratings used in x-ray and UV experiments at synchrotron facilities and scientific research institutions. This advanced technique, commercialized by Inprentus, utilizes a mechanical nano-scale scribing process that creates high-precision patterning of surfaces. Inprentus can scribe grating lines with blaze angles below 1 degree with an accuracy of 0.1 degree or better, without the need for ion-milling or other post-processing. Novel interferometry techniques developed at Inprentus allow for grating lines to be positioned with accuracy better than 20 nm over distances of 10 cm or larger. Using this technology, Inprentus creates gratings with resolving power up to 100,000, unprecedented for mechanically ruled diffraction gratings. Inprentus diffraction gratings are a core component of synchrotron spectrometry instrumentation, allowing scientists to discover and characterize new material properties in life science, engineering and physics research.
