Opto-Mechanical Assemblies

II-VI Optical Systems recently built a new assembly area utilizing the latest techniques in lean manufacturing. U-shaped work cells in modular and reconfigurable work areas are used to efficiently manufacture precision optical assemblies. This assembly area also makes use of automated electrical and environmental test chambers, high tech lens alignment tools, and in-situ optical testing at 0.633, 3.4, and 10.6 micron wavelengths.

II-VI Optical Systems assembles and tests all types of optical and electro-optical sub-assemblies with challenging specifications including electronic integration. II-VI Optical Systems 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.

II-VI Optical Systems offers a series of F/1 long wave infra-red (LWIR) fixed focus objectives with fine adjustment operating in the 8-14 μm spectral region. These LWIR objectives are manufactured for high optical performance with an easily adjustable focus. A wide range of standard field-of-views are provided for various applications. II-VI Optical Systems also provides customized LWIR objectives engineered and built to customer requirements. Optional camera integrations are available upon request.

Assembly Technology

II-VI Optical Systems' Assembly area is equipped to provide simple to complex opto-mechanical and opto-electronic assemblies. The Assembly group builds assemblies to established engineering drawings as well as refining current optical designs to reduce cost and/or improve performance. With over 100 years of combined hands-on experience, II-VI Optical Systems can also design and test precision optical assemblies based on your concept. Realization of assembled products is accomplished through leveraging manufacturable solutions by establishing realistic component and sub-assembly specifications and by carefully considered design of specialized alignment tooling. In-house testing capabilities include interferometric, spectrophotometric and light polarization measurement as well as mechanical, electrical, environmental and laser damage testing. II-VI Optical Systems currently has 4,000 square feet of class 1,000 work stations located throughout the class 10,000 assembly area dedicated to current and future manufacturing of optical assemblies.

Bonding Technology

II-VI Optical Systems is proficient in various types of optic-to-optic bonding methods including optical contacting, UV cure bonds, and chemically activated bonds. Optic-to-metal bonding processes utilize MIL-SPEC adhesives, sealants and potting materials as well as soldering of optical components into housings to form a hermetic seal or to facilitate efficient heat transfer. 

II-VI Optical Systems utilizes a proprietary chemically-activated bonding method referred to as the V-LOCK bonding process. The advantage of this process over traditional methods is in it’s ability to provide superior bonding of both similar, and a multitude of dissimilar, glass and crystal materials.
II-VI Optical Systems will employ optimum bonding methods, depending on your application.
