Freeform Micro-Optics Reel Off New Applications
Freeform Micro-Optics Reel Off New Applications
Tools are needed that can bridge the gap between conventional and emerging micro-optic concepts to improve the design workflow. Leveraging innovative fabrication technologies, freeform micro-optics are redefining the landscape for general lighting, anti-counterfeiting, and other applications. Companies such as Synopsys are starting to integrate CAD platforms such as RSoft that have traditionally been used to design photonic structures and waveguides with LightTools illumination design software.

Non-Contact Thickness Measurement
Bristol’s non-contact thickness gauges utilize the unique properties of light to precisely measure the critical parameter of thickness. Both hard and soft transparent and semi-transparent materials are analyzed without damage or deformation. Up to 31 layers can be measured simultaneously. Reliable accuracy, straightforward operation and rugged design make these instruments ideal for both laboratory and manufacturing environments.
