Manufacturing
From manufacturing, to assembly and testing, II-VI Aerospace & Defense collaborates with your product development team from initial concept through prototype development all the way to full-scale production to deliver comprehensive turnkey solutions. II-VI Aerospace & Defense has developed many state-of-the-art processes to optimize dimensional accuracy, optical surface figure and mechanical stability of diamond turned substrates. We have pioneered many of the major advances in diamond turned optical components and assemblies.
II-VI Aerospace & Defense assembles and tests all types of optical and electro-optical assemblies and sub-assemblies with challenging specifications including electronic integration. II-VI Aerospace & Defense is well known for producing high performance window assemblies, some quite large, which typically include distortion free bonding, EMI grids, heater blankets, electrical connectivity directly to the window via wires or adhesives, and integration with various sensors.
Among our full range of precision manufacturing solutions, we offer a computer-controlled deterministic polishing process to fabricate high precision aspheric components. We have the advanced technologies needed to produce very steep aspheric components in a wide variety of materials. Combining this with our high-precision metrology, allows us to achieve superb results for virtually every application.


Turnkey Solutions

IR Lens Assemblies | Axicons and Waxicons |
Over the past several years, our diamond turned products have seen an exponential growth in demand for many applications. These include: missile warning optical systems, IR sensing systems for Homeland Security, infrared search and track systems, a broad range of transmissive IR optics and systems, snap-together telescope designs, numerous reflective TMA telescopes and focal plane array back thinning.
Aspheric & High Complex Components
II-VI Aerospace & Defense entered the complex aspheric components manufacturing market several years ago as a production enabler for some of the world’s most sophisticated telescope assemblies.
Among our full range of precision manufacturing solutions, we offer a computer-controlled deterministic polishing process to fabricate high precision aspheric components. We have the advanced technologies needed to produce very steep aspheric components in a wide variety of materials. Combining this with our high-precision metrology, allows us to achieve high quality results for virtually every application.


Assembly
II-VI Aerospace & Defense has pioneered many of the major advances in diamond turned optical components and assemblies.
There have been many state-of-the-art processes developed to optimize dimensional accuracy, optical surface figure and mechanical stability of diamond turned substrates. Our founders were instrumental in developing the diamond turning process used to produce the first truly high-performance “snap-together” off-axis imaging system.
Precision Assembly & Alignment
II-VI Aerospace & Defense assembles and tests all types of optical and electro-optical assemblies and sub-assemblies with challenging specifications including electronic integration.
Testing
Testing and inspection is conducted at every phase of the production process to ensure full compliance with customer specifications. At II-VI A&D, our products are frequently tested under the environmental conditions in which they will be used. This includes humidity, temperature, rain and sand erosion, salt fog, salt-water submersion, shock and vibration testing.
Our testing capabilities and equipment include visible and IR interferometers to measure surface form and/or transmitted wavefront; a white light interferometer to measure surface roughness (non-contact); visible and IR spectrophotometers to measure optical transmission and reflectivity; a Dektac surface profiler to measure coating thickness; various environmental test chambers (humidity, temperature and salt spray/fog) a Form Talysurf profilometer; holographic measuring capability for diamond turned aspheric surfaces; and a coordinate measurement machine (CMM).
