General information
- Short Summary
- A new process developed by a German university improves the measurement capabilities and monitoring of optical material properties in the production of optical components, such as lenses. The university is offering a license agreement and the opportunity to jointly develop the technology further as part of a technology cooperation.
- Full Description
-
In optical component development, and especially for plastic lens systems, it is critical that material properties be known as precisely as possible – properties such as dispersion, or the frequency-dependent refractive index. But these material properties depend on such factors as manufacturing processes – on injection molding parameters such as temperature and pressure, for instance. Since quality requirements are very high in the mass production of smartphone cameras, optical sensors for automobiles, and the like, material properties resulting from temperature and production parameters must be monitored.
A new method developed by a German university ascertains dispersion (refractive index wavelength dependency) with a simplified setup that features no moving parts and does not even have a wavelength scan. The resulting precision is lower than that of current commercial refractometers, but the movement-free setup and high measurement speed allow parameter studies that could not previously be achieved.
This technology offer mainly addresses manufacturers of optical measurement and manufacturing systems, lens and objective manufacturers as well as camera module producers.
The university is offering a license agreement and the opportunity to jointly develop the technology further as part of a technology cooperation. - Advantages and Innovations
- A major advantage is that the material properties are easy to monitor in production and work processes, so that the effects of preset production machinery on the final product’s optical quality can be assessed. Large measurement series with lots of samples and various production parameters can also be used to create a robust material database – which could include a spectrum expanded into the IR range. This may also be commercially attractive to manufacturers.
