Using diffractive optic elements

IMOS diffractive optics bend light

The superb possibilities inherent in microstructure technology come into their own here. Because of the wave-like nature of light, the finest microstructures are suitable for light deflection. This permits the generation of numerous variants and the presentation of numerous lenses.

 

All operations specific to your task, from complex calculations to the finished precision optics, are controlled by the IMOS quality management system.

 

IMOS manufactures diffractive optics in synthetics, glass and silicon.

The IMOS instruments for DOEs are of the highest precision

Our Research & Development division has designed all manufacturing steps for our DOEs in such a manner that they can be carried out swiftly and reliably. Serial production that meets our quality standards, has been par for the course for us for a long time.

 

Not only do we produce diffractive optics that already comply with industrial standards, we are also in a position to develop diffractive optics entirely according to your requirements.

 

Starting with the mathematical calculations, through intermediate inspections and simulations, right through to the functional, isolated precision optical element in glass or synthetics. With the diffractive optics of IMOS, you can endow your light source with completely new capabilities.

The diffractive structures of IMOS create new opportunities

Enlargement of the DOE structure

Pixel sizes of 500 nm (= 0.0005 nm) to 1500 nm are used for light diffraction structures.

 

The diffraction structures can be expressed in synthetics so as to be accurate in every detail.

 

Where the collimated light ray shines perpendicularly through the DOE structure is virtually irrelevant. Because the presence of only a small number of pixels is enough to bend the light in such a manner that the desired light distribution occurs on the image plane.

IMOS Diffractive Optical Elements (DOEs)

DOEs are diffraction structures. They can be expressed in synthetics so as to be accurate in every detail. It does not matter where exactly the laser beam perpendicularly shines through the DOE structure. The light is bent by means of the finest microstructures and nanostructures so that it can project the desired complex information.



DOEs stipulate the direction and form of the collimated light of a laser. DOEs unite the functions of various optical elements in one, and yet are only a few millimeters in depth. This low space requirement is a definitive advantage.

Projection with DOEs

Light grid projection

Light-intensive projections can be generated with DOEs.


The diffractive structures of DOEs create wave fronts of light, which have either a self-negating or a self-reinforcing effect. By means of only a small number of pixels, light distribution is configured in such a manner that the desired projection occurs on the focal plane. Some DOE structures are today used as standard, for example grids with lines, circles, or dots.
