Diffractive Beam Splitter

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.

Diffractive beam splitter.

Beam splitter elements are diffractive optical elements used to split a single laser beam into several beams each with the characteristics of the original beam except for power and angle of propagation. 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. Each individual splitted beam inherits the basic properties of input beam such as polarization phase and size. Contact a sales expert.

Such a device was used in three pickup tube color television cameras and the three strip technicolor movie camera. 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. A diffractive beam splitter is used with monochromatic light such as a laser beam and is designed for a specific wavelength and angle of separation between output beams. The split orders are identical copies of the incident beam identical in parameters such as size divergence intensity distribution polarization and beam quality.

Used to produce arbitrary phase and amplitude distributions. 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. This will produce a focused multispot pattern with an inter spot distance defined by the customer at a specific working distance. You use diffractive diffusers from jenoptik to absorb a monochromatic laser beam and scatter the light into any imaginable pattern.

Holo or can manufacture a diffractive beam splitter pattern directly on plano convex lens. What are fan out diffractive beam splitters. 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 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. Typically diffractive beam splitters are used in combination with a focusing lens. There are two basic design approaches to producing a diffractive beam splitter. Each output beam retains the same optical characteristics as the input beam such as size polarization and phase.

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. 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.
