Custom Grating Design

At Inprentus, we understand that grating quality and design have a big impact on your optical system’s performance.

In-house optical engineers can customize your own design for your needs, or design from scratch
Inprentus will work with you to design and calculate simulated specifications and assist you with your grating design for custom instrument restraints

Synchrotron and FEL Gratings

We have created over 50 custom gratings for a wide range of Synchrotron and FEL beamline upgrades and commissionings. We work with you to custom-design your optic and provide simulations of in-beamline performance. Our gratings will greatly enhance throughput and efficiency for your beamline.

Industry-leading fast delivery times
High efficiency and resolving power
Variable line spacing (VLS)
Blaze angles as low as 0.1 degree
Large gratings up to 500mm in length
Simulation services to provide reliable predictions of in-beamline efficiency

Synchrotron and FEL Gratings

Metrology Services

Let Inprentus provide you with world-class characterization of your optic. Options include:

Fizeau Interferometry for resolving power
Atomic Force Microscopy for groove shapes, dimensions, and roughness
FIB / SEM to image nano-scale features
2 Circle Diffractometer for optical blaze angle measurement
2 Circle Diffractometer for stray light measurement
Absolute Efficiency measurements
