Q2- 2017 Newsletter



 



Holo/Or thanks all customers that came to
meet us at the Photonics West in San Francisco and at the 
Laser World of Photonics in Shanghai. For
those who did not make it, we will be participating in the Laser World of
Photonics expo in Munich for the first time in our own Booth!
  You are most welcome to visit us.

Next Exhibition – Laser World of Photonics
Munich – 26-29 June, Messe Munich, Germany.



 



Holo/Or will be participating in Laser World of Photonics Munich, bringing new products to answer our customers
evolving beam shaping needs. Come and visit us at Hall B3, Booth 108, Messe
Munich Germany.        






What's
New



 



New product releases in Q1-Q2 2017       





In the first half of 2017, Holo/Or has
added 193 new designs, including large angle line Top-Hat designs (up to 10
degrees at 1064nm), M-shaped homogenizers for applications involving 
sintering and heating on highly heat
conducting surfaces, a 1X4 beam splitter with reduced undesired orders for
sensitive parallel processing and a new product category- mode
converting phase plates
. Check our product
release page
for the latest new designs that are
available with no NRE cost.




         



Resizing of existing designs is now offered
at reduced cost and short lead time

By investing in new production
technologies, Holo/Or now offers our customers the ability to resize existing
designs to different element size at reduced cost. If you find an existing
design that fits your needs in our extensive products
page
, but the element
size does not meet your requirements, do not hesitate to contact us to resize
the element. Resizing is available at significantly lower cost compared to a
new custom design, and will only add 1 week lead time to the order. You are
welcome to contact us for more details regarding specific products.



 



Applications



                               



High Efficiency 2X2 beam splitter              



Following the success of our high
efficiency double spot design (HEDS), Holo/Or has developed a High Efficiency
Quattro Spot (HEQS) 2X2 beam splitter. This new product offers splitting
efficiencies of >98%, compared to 64-79% efficiency of regular 2X2 beam
splitters. HEQS 2X2 splitters work best with multi-mode lasers, and enables an
independent tuning of the spot intensities to achieve desired uniformity or
correct system induced non-uniformity. This design is highly useful in material
processing application, to reduce undesired orders and improve throughput. Read more about it here



                               





Tailored Diffusers – Custom diffusers with reduced
zero order and sharper edges



Holo/Or has recently developed new
algorithms for the design of custom diffusers for aesthetics and heat treatment
applications. In these applications, it is often required that the illumination
profile be very smooth, without a rise in center caused by zero order. Also,
sharp edges (short transition length) are often required of the diffused spot,
to give accurate energy doses without overlap when moving the spot on a
surface.

 




Using our new methods, it is possible to
design high angle diffusers that have almost now zero-order effects, while
maintaining sharp edges. Contact us to inquire about designing your own
application-tailored diffuser.




 




 




 




Technical Tips




 




Integrating Homoginzers in Zemax™ Using
our  BSDF files




Holo/Or continually strives to offer value
to our customers and potential customers by providing them with free modelling
to enable integration of our DOE into common optical simulation setups.
Recently, we have added a method of simulating our Homogenizer elements (Flat
top diffusers) in Zemax™ by using BSDF scattering files.




These BSDF files are offered free to
download for most of our existing Homogenizer designs – click the
"tools" column for the desired product in our product page to
download.  You can read more about BSDF files
in our Manual




         







Modeling beam splitter DOE in Lighttrans™
using Blackboxes




 




Holo/Or has recently added Black Box models
of our Diffractive Beams Splitters in VirtualLab Fusion™ - a Physical Optics
Software. These Black Boxes allow our customers to utilize the full range of
simulations analysis and systems optimization. Each Black Box is supplied as a
basic optical setup including a Gaussian source, a Black Box of a Diffractive
Beam Splitter, an ideal focusing lens, and a screen.




The Black Box includes the complex data of
the diffractive design and will work nominally for any wavelength defined by
the Light Source element.
