System Integration
Integrate your meta-surface components into optical systems with 3rd party ray-tracing and CAD software. Full system design is a prerequisite to capture the full advantages of Meta Optics.
Fast, Accurate on Time Delivery of Projects
The right tools, people and the right methods matter. Proper methods and execution keep the project on schedule and on budget.
Keep your IP
PlanOpSims unique business model allows for the transfer of the IP after a succesful project has been completed.
Fabrication Assistance
PlanOpSim has years of experience putting customers in touch with the right fabricators with the right fabrication technology for any run ( large volume, small prototype, etc ). We can and will take their design rules into account while designing.
Software Customization
You want the software that models the parameters you need, for the applications you are focussing on. PlanOpSim can deliver custom features, interfaces and even entire models tailored to your wishes. In the past we have delivered the following algorithms for specific analyses:
Light emission and micro-cavity effects in birefringent materials: liquid crystal lasers and OLEDs
Algorithms for calculating light extraction and efficency of OLEDs
Identification of plasmon modes for material characterization and loss analysis
Optical modelling
PlanOpSim’s primary expertise is numerical modelling and design of thin film and other optical components. Next to PlanOpSim’s own tools, we use third party tools as required for the task:
Finite Difference Time Domain simulations of micro-optics
Non-sequential Ray tracing for non-imaging applications: solar concentrators and LCDs
Design of thin film light emitting devices
Measurement and Characterization
Optical measurement setups for light scattering,
Photometric characterization of (O)LEDs
Characterization of thin films, determination of refractive indices, birefringence and absorption
These are just the areas in which we already have extensive experience. We never shy away from new challenges

Project showcase
Multi-level diffractive lens
Project statement
❖ Diffractive optical element lenses (DOE) are used for
their small volume in optics for beam shaping,
imaging and other optical systems.
❖ Single layer DOEs are known to cause low efficiency
due. This is an inherent feature of single layer
components.
❖ For these applications the requirements are
➢Control output light shape
➢Single component (robust + lower cost)
Project results
Multiple DOEs designed, the
efficiency increases with increasing
# of layers until it saturates near the
efficiency of a continuous ‘kinoform’
lens
❖ The relation between the number
of layers, step width and focusing
efficiency was simulated
❖ Focusing efficiency in the primary
and higher order spots was
simulated
