Custom Transmission Gratings

High Quality, Low Stray Light Custom Transmission Gratings

At Holographix, we work closely with our customers to assist them in the development of custom transmission grating-based solutions from concept to production. We have successfully advanced the design and manufacturing processes for custom transmission gratings. This approach allows us to produce surface-relief components that consistently meet or exceed the performance of volume gratings, but at a fraction of the cost! Holographix differentiates itself from the competition by offering:

Optical Design:

Our optical design team fully utilizes the unique abilities of Holographix’ proprietary replication materials to develop high aspect ratio solutions required to meet our customers’ transmission grating specifications.

Exceptional Performance:

Holographix produces transmission gratings with high diffraction efficiency in both polarization planes (low PDL) and with low stray light. Our customers confirm our independent test results: Holographix’ custom surface-relief transmission gratings provide superior performance compared to Volume Phase Holographic (VPH) gratings!

Development Flexibility:

Unique replication technology allows for state-of-the-art transmission grating-based solutions. Our proprietary replication materials are capable of producing exceptionally high aspect ratio gratings. This capability allows Holographix the freedom to design and produce custom gratings that are not achievable elsewhere.

Manufacturing Excellence:

High quality, custom transmission gratings with repeatable performance! Holographix is ISO 9001-2008 certified, and proudly manufactures all optical components in the USA.

Why Choose Holographix as your Transmission Grating Supplier?

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

Transmission Grating Mastering

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

Transmission Grating Replication

Holographix manufactures custom transmission gratings using our proprietary replication technology. Transmission 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 the most demanding transmission grating applications.
