With new technology, Holo/OR has expanded the manufacturing options for diffractive optical elements (DOEs), thereby significantly reducing the cost of mass production of low and medium power optics in medium and large quantities.
In the new polymer-on-glass (POG) optics, the polymer layer that has DOE structures is applied to one side of a stable quartz glass substrate. The other side can be equipped with an antireflective coating for the wavelength used. POG optics offer a laser damage threshold of more than 10 J/cm² for laser pulses of 8 ns at 1064 nm. With a high transparency in the wavelength range between 450 nm and 1080 nm, they are suited for many types of lasers in the visible and infrared range.
POG DOEs are used as beam shapers and splitters in applications such as 3D sensor technology, medical technology, and industrial image processing.
