It is difficult to achieve realistic, diffraction-limited results using Zemax OpticStudio¢â simulation software tool when designing a system with DOEs integrated in it. This is especially true near the focal point of the system, and for multi-mode lasers.

Nonetheless, Zemax geometrical RayTracing methods are much faster and better developed than physical optics methods.
Therefore, and due to the fact that many of our customers use this modelling software to design their systems, Holo/Or has recently published an article on a new method to achieve realistic, diffraction-limited results using scattering models.
This is especially useful for modelling multi-mode laser behavior with focusing systems, and for getting realistic transfer region in beam shapers. Read our full article.

New Products

 

Scanning HEDS Beam Splitters

Customers involved with many laser applications- including welding, cutting, brazing and perforation, can benefit from the use of our HEDS family of 1X2 beam splitters, which offer high efficiency splitting.  Based on your feedback, we have designed an improved version of the HEDS, optimized for scanning double lines. These Scanning HEDS have no effect on the line width of the scanned lines, even for single mode lasers. They also maintain diffraction-limited line width when used in scanning applications while maintaining high efficiency (>95%).

Diffractive Lens Arrays

 


Many laser applications require precise and efficient diffusers at low angles. Holo\Or¡¯s new diffractive lens array diffusers have total (<10-5) ROC accuracy and feature diffraction efficiencies of ~ 95%, with no dead zones between the lenses.
