Laser Material processing |
|
Experienced
Material Processing Teams know that most laser processing jobs will perform
better with a Top-Hat
Shape. This shape applies a well defined spot to the material, and enables
sharp and accurate transitions in the material under process.
A uniform spot enables equal
treatment to a surface, excluding over/under-exposure of specific areas. In
addition to that the spot is characterized by a sharp transition region that
creates a clear border to the treated and untreated area.
HOLO/OR also delivers beam multiplication solutions for various industries where there is a need
to perform Laser perforation in thin sheets of Material as for the following applications:
- Plastic and metal sheets in
the packing industry to Enhance shelf life of foods
- Labels to indicate the
day of manufacture or end of use date
- Paper Carton
- Metal foil to enable
easy tear-off
- Filters for cigarettes
- Tubes for Liquid or Gas
Drainage
- Pre-weakening of metal
sheets for airbags in the car industry.

Diffractive Optics for Medical
Applications |
|
Specific requirements
for optics in medical applications are not always met by conventional bulky
optics. Laser systems for surgery and welding require sharper focusing,
convenience of targeting, simultaneous exercising of several points,
straight lines or even curved contours, while laser therapy requires
uniformly illuminated circular or rectangular area under treatment.
Diffractive optical elements (DOEs) open new degrees of freedom in light
transformation and offer basically new opportunities for optical systems.
Even though DOEs are well known, medical applications demand more oriented
investigations on light diffraction, materials and tests.
HOLO/OR offers a large choice of diffractive optical elements for medical
applications including:

Laser Beam
Splitting |
|
Recent advances in diffractive optics theory and
technology have
made beam splitting a valuable resource
for optical designers.
Programmable, multichannel optical systems can be designed
based on diffraction gratings, lenslet arrays and
digital holography
algorithms. Spot array
generation, multiple and multifocal imaging,
matched filtering, laser beam mode selection and simultaneous
contour shaping are among the most promising applications of
diffractive beam splitting today.

Diffractive
optical elements have found many applications in the field of Astronomy. One
of the recent applications make use of an optical Vortex Lens in order to
detect light from distant planets by blocking light from parent stars. HOLO/OR offers a large choice of diffractive optical elements (DOEs) for applications in
Astronomy including:
