Why Choose Holographix as your Slanted Grating Supplier?

 

Holographix offers customers a turnkey solution to their diffraction grating-based optical system needs, from design of custom diffraction grating masters, to reliable and repeatable manufacture of replicated diffraction gratings and opto-mechanical assemblies, in production quantities.

 

Slanted Grating Mastering

In order to provide high quality custom replicated diffraction gratings, a high quality master mold is required. Holographix has developed a proprietary ion milling process that allows us to manufacture custom slanted masters of exceptionally high quality. Our unique process allows us to produce large area slanted masters.

Slanted Grating Replication

Holographix manufactures custom slanted gratings using our proprietary replication technology. Slanted gratings are replicated from custom Holographix supplied, or customer provided master molds. Our replication process is capable of producing a wide spectrum of pitches and aspect ratios. Holographix’ replication process is also suitable for a variety of other profiles including sinusoidal, rectangular (binary), multilevel, slanted or undercut, as well as high aspect ratio profiles for both transmission and reflection applications.

 

Opto-Mechanical Assemblies

Holographix is well positioned to add value to our custom diffraction gratings by taking them through the next steps in your assembly process. Holographix has the capability and experience required to support your production requirements ranging from simple component/mount assemblies to more complex assemblies involving the build-out of fully aligned optical systems.
