Elongated Focus Products

Holo/Or's elongated depth of focus is a new solution achieving extended depth of focus as well as high lateral resolution (small beam waist).
Optical elements that present these two conflicting characteristics simultaneously are needed for a variety of applications, including:

  • Laser drilling and cutting in transparent materials (Glass, silica, …)
  • Microscopy
  • Profile measurements
  • Precision alignment

Conventional optical elements (spherical lenses, mirrors, etc.) cannot achieve these two goals simultaneously; high lateral resolution requires high numerical apertures (NA), whereas long depth of focus requires low NA.
Our novel method achieves a focal "cylinder" with sharp edges and extended depth of focus, while keeping the laser spot size very small.
The new solution completes the existing family of multifocal products. The benefit of the extended focus, vs. Multifocal products, is that it produces a continuous intensity profile along the DOF, and doesn't suffer from areas with low energy between neighboring focal spots

DOE Tuner Module

  Elongated Focus Products Holo/Or’s elongated depth of focus is a new solution achieving extended depth of focus as well as high lateral resolution (small beam waist). Optical elements that present these two conflicting characteristics simultaneously are needed for a variety of applications, including: Laser drilling and cutting in transparent materials (Glass, silica, …) Microscopy […]
