PlanOpSim develops dedicated R&D software for simulation of metalenses, diffractive optical elements, holograms and planar optics. PlanOpSim's numerical modelling can be used for design of nano-structrured optics, flat lenses and optical system integration. Planopsim has extensive experience in optics and photonics and is available to support your projects on a freelance or consulting basis. Our team has concluded several projects in: *Modeling of photonic devices: metalenses, diffraction gratings, displays, solar cells and more *Development of measurement setups *Modeling of liquid crystal and OLED display and other devices *Characterisation and fabrication of thin film devices
