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.

Each individual splitted beam inherits the basic properties of input beam such as polarization phase and size. What are fan out diffractive beam splitters. 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. Beams are usually separated into 1d or 2d arrays and may be arranged regularly or irregularly.

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. You use diffractive diffusers from jenoptik to absorb a monochromatic laser beam and scatter the light into any imaginable pattern. 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. Each output beam retains the same optical characteristics as the input beam such as size polarization and phase.

Binary and analog solutions. There are two basic design approaches to producing a diffractive beam splitter. 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. 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.

Used to produce arbitrary phase and amplitude distributions. 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. Holo or can manufacture a diffractive beam splitter pattern directly on plano convex lens. If so the output beam array becomes an array of focused spots at a certain distance behind the lens.

A diffractive beam splitter splits the incident laser beam into a 1 dimensional or 2 dimensional array of beams. Contact a sales expert. The split orders are identical copies of the incident beam identical in parameters such as size divergence intensity distribution polarization and beam quality. The diffractive element that produces a beam splitter is basically a grating with some complicated shape that generates the desired distribution of spots.

This will produce a focused multispot pattern with an inter spot distance defined by the customer at a specific working distance. Typically diffractive beam splitters are used in combination with a focusing lens.
