Blazed Diffraction Gratings
Blazed Diffraction Gratings for Research FEL and Synchrotrons
Inprentus has worked with governments around the world to provide the most advanced blazed diffraction gratings for synchrotron and free-electron laser facilities.
US-based government customers include Lawrence Berkeley National Laboratory, Brookhaven National Laboratory, Stanford Synchrotron Radiation Laboratory, Argonne National Laboratory, and NASA.
Spectral Beam Combining Gratings for High Energy Lasers
Inprentus manufactures radiation-hard, metal-master diffraction gratings for High Energy Laser (HEL) systems used in counter-UAS and directed-energy applications. In Spectral Beam Combining (SBC), our high-efficiency, high-damage-threshold gratings concentrate multiple laser beams into a single high-power output in the 10–50 kW range. Our master gratings are ruled directly into metal—making them inherently rugged and radiation hard—with multi-layer dielectric overcoats for high laser damage thresholds.
Built to scale: Our modular digital ruler architecture, built from off-the-shelf components, goes from start of assembly to start of production in three months. With 24-hour production, >70% manufacturing yield, and a fully domestic design-and-manufacturing supply chain, we're positioned to scale HEL grating production and strengthen the directed-energy supply chain.
Technical capabilities: sizes up to 600 mm · groove densities 50–6000 lines/mm · blaze angles 0.1°–90° · surface roughness <1 nm rms · constant and variable line spacing · flat, curved, and freeform surfaces.
Waveguides for Military Applications
Inprentus can work with you to design and integrate a fully-blazed diffraction grating waveguide into your Augmented Reality display, including headsets and heads-up displays (HUD). Our waveguides reduce eye glow and increase optical efficiency for superior performance PLUS offer unmatched ease of replication
Blazed Diffraction Gratings for Gas-detection Sensing Spectrometer
Inprentus’ blazed diffraction gratings are used in spectrometers for gas-detection, identification, and quantification.
