Custom Optics and Crystals Quality

ADVANCED
Optical Materials, Design and Manufacturing

Inrad Optics fabricates optical materials to exacting quality standards and incorporates those materials into advanced optical components, assemblies and systems. Our materials know-how is reflected in our broad portfolio of standard and build-to-print optical components—including large form factor, extreme precision components, bent crystal assemblies, and metal optics. Our optical design-for-manufacturability expertise allows us to execute even the most challenging custom optics designs.

Our Mission
We improve the world’s safety, security, and scientific understanding by transforming challenging requirements into optical realities.

Crystals to Components

We produce optical materials to the highest quality standards. At our facility in New Jersey, we have developed proprietary methods for processing optical crystals, diamond turning and surface treatment methods for metal optics, and micro-thinning of x-ray crystals for spectroscopy applications.

Optical Problem Solving

Working on a build-to-print basis or as part of your design team, we specialize in the integration of optical components into mechanical assemblies and electro-optic systems.

Zinc Germanium Phosphide (ZGP)

Zinc Germanium Phosphide (ZGP) is one of those few reliable, efficient, high quality non-linear crystals that is beginning to dominate applications in a particular spectral region due to the unique properties of the material. A high non-linear coefficient (75 pm/V), good thermal conductivity (35 W/mK), relatively high Laser Damage Threshold (2-5 J/cm2 typically), and transparency with phase-matchability over the 2 μm – 8 μm range (and beyond) highlight the desirable properties of the material.

Guidelines to Metal Optics Roughness and Flatness

Although a mirror’s surface appears smooth to the naked eye, if you looked at it through a microscope you’d see many peaks and valleys. These surface imperfections can cause interference with light waves and other electromagnetic radiation. For this reason, understanding the degree and nature of this interference is crucial to successfully designing a metal based optical system.
