Diffractive optical elements (DOEs) offer the ability to change the intensity or phase profile of a beam of light. Creative Microsystems produces custom diffraction elements including beam shapers, homogenizers and coherence randomizers specifically designed to produce a desired beam profile.
Diffractive optical elements can duplicate most of the functions provided by refractive optical systems. Some of the unique functions that DOEs provide are multiple function optics, unusual configuration, and narrow spectral response. These typical characteristics of DOEs provide advantages in beam combiners, head-mounted displays, spectral filters, compact rugged spectrometers, diode laser couplers, laser aresonators, laser material processing, beam shaping optics, laser collimators, computer interconnects, solar concentrators, and wavelength division multiplexers/demultiplexers. Large aperture DOEs are useful for null optics, laser scan systems, laser beam delivery systems, and projection displays
