Advanced manufacturing of precision optics using proprietary nano-scale contact-mode lithography techniques. Inprentus has developed a new method for manufacturing mechanically ruled blazed diffraction gratings for augmented reality waveguides, synchrotron, FEL and laser applications, offering high resolving power with blaze angles lower than 1 degree. These new diffraction grating products offer a new level of capability to apply to AR optics, spectrometer, monochromator and laser instrumentation.
