Prototype and production of electro optics
in production. 3. Critical Design Review. The final optical design with tolerances showing yield relative to specifications is produced. The goal is to release all parts for fabrication.
4. Prototype. Prototype units are tested and built. Update prints are also produced concerning any manufacturability issues that are uncovered. Any required qualification tests and performed, and production process improvements are identified.
5. Low-Rate Initial Production (LRIP). Improved designs and processes are implemented and designed. Prints are refined if any further manufacturability issues are uncovered. Designs are placed under full production design control.
6. Production. Routine production is initiated under ZYGO EOG’s ISO 9001 certified quality system. Automated electronic data management for larger volume programs is implemented. Once we have a finalised and viable

any electro-optic devices are expensive and used in mission
critical end-use applications, and so there is no room for error, and customers must have the confidence and trust in their chosen supplier to deliver to budget and on-time. Program management covers all
aspects of the design and development of advanced electro optic devices, including the full cycle of product development from proposal and design, through prototype development and analysis, to product development and manufacturing. It is therefore vital that your chosen supplier should have a detailed and transparent management process, which is at the same time instantly accessible to all parties, and contains the detail and agility to respond to unforeseen circumstances in a timely and cost- effective manner. ZYGO’s EOG programs follow a standard
process to get from idea to finished device. The schedule is published as a Microsoft project document, and is

typically reviewed and updated on a weekly basis by all relevant team members.
ZYGO’S 6-STAGE PROJECT MANAGEMENT PROCESS 1. Specification Development. ZYGO’s EOG works closely with the customer to develop first order candidate designs and review specifications to determine the technical and commercial feasibility of the proposed project. Specifications that are key cost and performance drivers will be identified and alternatives will be proposed as applicable.
2. Preliminary Design Review. A preliminary optical design and mechanical model is produced with estimated performance (including preliminary Finite Element Analysis [FEA] where appropriate) relative to specification. The key goal is to develop the proposed design to the point that long lead-time items can be ordered thereby eliminating unnecessary delays
design, the prototypes and production can be bid on a firm fixed basis. We don’t bid prototypes and production until the design is at the state where we can get quotes for materials. This allows out-of- the-box accurate and detailed pricing which barring major unforeseen circumstances should see little budget variation moving forward. When embarking on an electro-optic
device development project you want to make sure that your chosen supplier not only has the best equipment to hand, but they have the experience, knowledge, versatility, passion, drive, and enthusiasm to get the most out of it. Values, knowledge, and competencies combine to get the best results. To manage surge capacity in ZYGO’s
EOG we can access a network of consultants that have been associated with us for years or, bring in resources from other groups in Zygo Corporation. Regardless of how the project is staffed we will always be clear about the expected schedule, and demonstrate the ability to keep resource levels optimised for project success on time and to budget.
