A Unique Cost Effective Solution
Holo/Or’s Polymer on Glass (POG) elements are the most accurate beam shaping solutions available for the low to medium power-range applications. They are cost effective, and can be produced in high-volumes as per customer requirements. POG elements can be either beam splitting dot / line generators, or beam shaping products including homogenizers / diffusers with flat-top distribution, broad band diffusers and micro-lens arrays.
Material Compatibility:
- LDT > 10 J/cm^2 laser pulses at 8ns, 1064 nm
- Low angle tolerance < 2%
- High transparency between 450nm to 1080nm
- High environmental stability -40 to + 120 deg C, no yellowing in most common use scenarios
- Reflow soldering compatible at 260 deg C
- Flat, thin and lightweight components
- Cost effective, high volume production capabilities
- Delivery available on wafer, diced or un-diced, and as single parts
In the past few years, a sharp decline in laser power density prices, allowed for many new laser applications to emerge. Processes and equipment that were once blocked from using lasers due to their high cost entry barriers, are now thriving. Amongst those, the most prominent is the rapidly growing 3D sensing segment including mobile, automobile, metrology, surface inspection and mapping systems, robotics and home appliance applications.
To meet the beam shaping needs of these new and exciting applications, Holo/Or has developed a brand-new line of products, fabricated on Polymer on Glass instead of pure Fused Silica which is offered to the more high-end, high-power applications.
