Over the last couple of years In-Vision’s Product Development Team has grown substantially bringing on new people every year. By now, it consists of an optical design, a mechanical design and an electronics engineering group covering people from various disciplines.
We are one of very few companies to have their own optical designers. Working on both, our proprietary design software developed together with senior optical designers' experience of more than 30 years, and the industry standard Zemax, they regularly simulate new optical solutions. These simulations are calculated on state-of-the-art multi-core hardware.
It is paramount for the quality of the final product, that our optical designers have profound knowledge about different types of glass, workable geometries of prisms and the application and components of adequate coatings.
Our mechanical design group makes sure the product itself is robust and easy to assembly, also in serial production. Our designers regularly come up with innovative approaches so that In-Vision may manufacture a product fully aligned with the needs of the customers. In wafer lithography for example, we have developed a piezo-empowered focus mechanism that adjust the focus of the optical system to a level of 2µm on a 50 Hertz basis.
The mechanical designers mostly work on Creo software and dedicated programs for multi-physics simulations (thermal, fluid and mechanical simulations amongst others). All product revisions or versions are documented meticulously in our Product Lifecycle Management software Windchill.
The latest addition to In-Vision’s capabilities is electronics design. In 2015, we started ramping up resources in this area to complete our vision of a one-stop-shop for the customer. By now, we have a team developing hardware, software and field-programmable gate arrays (FPGA). Our developers work on Altium and simulations software such as Mentor Hyperlinks and Mentor Model Sim. For programming purposes VHDL, C, C++, C# or Labview are used among other programming languages.
Optical elements such as lenses, prisms or other flat optics are coated with certain chemicals to influence transmissive charteristics of the specific optical element. These chemicals are based on more than 200 proprietary recipes of In-Vision and tailored to the specific requirements of the overall optical system. The coatings are applied in manufacturing through electronic beam vaporization in our own vacuum-based coating centres.
