Diffractive Beam Splitter

Diffractive elements are thin phase elements that operate by means of interference and diffraction to produce arbitrary distributions of light or to aid in the design of optical systems.

Diffractive beam splitter. Typically diffractive beam splitters are used in combination with a focusing lens. A diffractive beam splitter is a diffractive optical element doe used to split a single collimated laser beam into several beams with the same optical characteristics as the original beam. The split orders are identical copies of the incident beam identical in parameters such as size divergence intensity distribution polarization and beam quality. A diffractive beam splitter splits the incident laser beam into a 1 dimensional or 2 dimensional array of beams.

If so the output beam array becomes an array of focused spots at a certain distance behind the lens. Fan outs are multi level doe components designed and fabricated with the aim of splitting an input beam into n x m beams with adjustable separation between them. Each individual splitted beam inherits the basic properties of input beam such as polarization phase and size. You use diffractive diffusers from jenoptik to absorb a monochromatic laser beam and scatter the light into any imaginable pattern.

What are fan out diffractive beam splitters. Beams are usually separated into 1d or 2d arrays and may be arranged regularly or irregularly. A third version of the beam splitter is a dichroic mirrored prism assembly which uses dichroic optical coatings to divide an incoming light beam into a number of spectrally distinct output beams. Such a device was used in three pickup tube color television cameras and the three strip technicolor movie camera.

Like the diffractive beam splitter the diffuser converts an input beam into a multitude of output beams the angle and intensity of which can be controlled. Each output beam retains the same optical characteristics as the input beam such as size polarization and phase. This will produce a focused multispot pattern with an inter spot distance defined by the customer at a specific working distance. Holo or can manufacture a diffractive beam splitter pattern directly on plano convex lens.

The diffractive beam splitter also known as multispot beam generator or array beam generator is a single optical element that divides an input beam into n output beams. Binary and analog solutions. The diffractive element that produces a beam splitter is basically a grating with some complicated shape that generates the desired distribution of spots. A diffractive beam splitter or multispot ms is a grating like periodic diffractive optical element doe used to split a single laser beam into several beams called diffraction orders in a predefined configuration.
