ffOptik - Free-Form Illumination Optics

Products

ffOptik^® is our high-performance software package for designing free-form optics.

ffOptik^® lets you design free-form lenses and reflectors for an arbitrary distribution of light on a target.

This applies to lighting streets or buildings just as well as to illuminating tiny spaces such as for scanning devices, touch switches or head-up displays.

Whether your problem is a homogeneous light distribution or the highly irregular distribution of your company logo - ffOptik^® is the tool of choice.

ffOptik^® is not a simulation program, instead it finds an exact solution by solving a differential equation whose result is a unique optical free-form surface.

A single optical surface can either guarantee a desired distribution of light on a target or a desired distribution of the direction of rays in the target.

With two simultaneously calculated free-form surfaces both, amount of light and ray direction in the target can be determined.

Examples

Reflector bounded by hexagonal prism

ffOptik offers many possible boundaries for a lens or reflector, such as cylinder, cone, prism or free-form curves.

Reflector bounded by free-form curve

The boundary for this reflector is an extruded free-form curve.

Surface Source

Lenses may have different entrance surfaces, such as spherical, Cartesian oval or free-form.

Non-rectangular target

Illumination targets can be of arbitrary shape and do not have to be planar.
