Why Choose Holographix as your Diffraction 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.

Diffraction Grating Mastering

In order to provide high quality custom replicated diffraction gratings, a high quality master mold is required. Holographix offers mastering services for the production of these molds to facilitate the manufacture of custom replicated gratings. Holographix specializes in the design and production of high quality custom surface relief diffraction gratings operating in transmission and/or reflection mode. We provide several types of custom master gratings including holographic, binary (E-beam), ruled, slanted-groove, and blazed.

Diffraction Grating Replication

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