The Challenge


- Useful to characterize, in optical bench, the diffractive profil·le independently and/or in combination of the refractive element.
- Useful to design new optical components and evaluate their properties before production.
- Useful to characterise an already manufactured hybrid Optical component and to compare it with its original design.

The Technology


Illuminating unit / Spatial filter: condenser (microscope objective) and pinhole / Lens and diaphragm / Beam splitter / Mirror / Spatial Light Modulator (SLM) / Lens (IOL) / Supporting structure (wet cell) / Microscope objective and tube lens / Acquisiton system / OT: object test / OP_S: Optical system / Ai: Arm i

Current stage of development


A first operational prototype has been built and tested.

Applications and Target Market


Testing physically new diffractive intraocular lens designs: Extended focus, trifocal, bifocal, aberration compensation. Also applicable to diffractive contact lenses.

Innovative advantages


The hybrid diffractive/refractive optics simulator is a rapid, economical and low consumption system in optical bench. Unlike numerical simulation, the proposed system provides empirical results, which are closer to the final behaviour of an optical component. This versatile system permits to characterize a diffractive profile independently or in combination with a refractive element before production.
