Holo/Or is a leading company in the field of diffractive optical design and manufacture. Among the more popular products offered by Holo/Or are Top-Hat beam shapers, used in many industrial micro-machining and materials processing applications, high-power beam homogenizers/diffusers, beam splitters/samplers for multi-spot and power monitoring applications, and Vortex lenses, used in metal-cutting and particle-trapping.
Holo/Or was founded in 1989 by Israel Grossinger., as a pioneer in the commercialization diffractive optical elements (DOEs). Back then, DOEs were found almost exclusively in various research institutes. Mr. Grossinger, occupying then the post of VP R&D at Indigo (sold later to HP), identified the commercial potential of this area. The first product manufactured at Holo/Or was the DWM (Dual Wavelength Module), proposed to a leading company in the field of medical laser systems, Coherent Medical. This was also the first commercial partnership of Holo/Or.
Holo/Or's Dual Wavelength lens was the first commercial DOE in the world. These lenses correct the strong chromatic and spherical aberrations between a CO2 laser and its red aiming, and unite both beams to a single diffraction-limited focal point beam, by the use of a diffractive surface pattern. This product continues to be used in surgical laser systems and FTIR systems.
The company has recorded several international patents. in various applications such as: IOL  (Intra-ocular Lenses), Fundus cameras, hair coloring diagnostics, guiding systems, portable scanners  and aesthetic laser treatment.
