Consumer expectations and industry requirements are constantly changing, and manufacturers should be aware of this as they progress through the production process. Whether it is camera resolution on interferometers or surface quality analysis on profilometers, it is vital to deliver customers an optical system that exceeds all measurable standards
The Need for Optical Components
While optical manufacturers follow metrology advances, optical engineers push material limits. Today's production floors are dominated by high-index glasses and crystals, as well as engineered polymers. The optical properties of these materials are unique, but they are challenging to machine and polish. Emerging materials require manufacturers to find an appropriate balance of consumables.
There is a need for reactive chemistry in every glass that has the latest chemical composition. This allows polishing technicians to achieve exceptional quality and remove material. Polishes and pads must be selected appropriately in today's manufacturing world. There are many variables involved in optics fabrication. Taking control of these variables gives us the opportunity to improve.
A deep understanding of optics and manufacturing processes is in high demand as technologies and manufacturing processes advance. U.S. optics manufacturers face a workforce shortage as their most pressing problem. Those approaching employment age have little interest in manufacturing because skilled laborers are retiring. The national workforce is experiencing a void that must be filled. The industry may have difficulty meeting increasing demand if there is a shortage of qualified personnel.
Developing technologies, consumables, and workforces
The industry is constantly evolving. It is crucial to align companies' expectations and performance by matching inspection methods. If the inspection methods are not aligned, third-party confirmations are available. It is common for independent contractors or metrology tooling manufacturers to measure components. It costs less for one-off projects, but more for long-term ones. Developing and maintaining cooperative relationships with the industry's leading inspection companies is essential. Optics are made or broken by manufacturing processes and consumable choices.
A blank is cut internally using raw materials directly from the glass manufacturers. Optimal results are ensured by homogeneity testing on transmission-sensitive projects. It is more efficient to take quality-assurance measures at the beginning of the production cycle. The best way to control quality is throughout the production process.
In an industry that moves at a rapid pace, the development of the workforce is vital. The knowledge of master opticians must be documented and passed on to tomorrow's technicians as they retire.
The American Precision Optics Manufacturing Association (APOMA) offers workforce development programs. Optical Manufacturing Technician Apprenticeship Programs across the country, as well as community college-based optical systems technology programs, are excellent programs that support workforce development. Future opticians will be defined by industry awareness and educational opportunities.
