Since 2014, HOLO/OR produces plastic DOEs. Low to medium power applications do not necessarily require DOE made of glass.
HOLO/OR offers low cost, mass production of diffractive elements using an injection molding technology. The main plastic types are: Polycarbonate, PMMA, Zeonex and Zoner.

Standard plastic DOEs

Our standard list is constantly growing with new DOEs available in plastic for mass production; All standard DOEs do not have antireflective coating.

Target DOEs

Multispot DOEs with the remark “target” is an element that produces a number of spots building a typical target, refer also to below image.

Random DOEs

Multispot DOEs with the remark “random” have a random pattern of spots, when 50% of the dot matrix are potential spots and will be “on”, and this is determined by a randomizing algorithm.

Standard MS DOEs

Multispot DOEs without any additional remark, show a homogenous distribution of the spots, as shown in the image below:

For custom DOEs

If you are interested in custom plastic DOEs, please provide the following data:

  • Description of application
  • Wavelength
  • Beam definition (diameter, input mode, divergence)
  • DOE dimension – if some specific values are needed
  • Working distance
  • Requested output shape at working distance
  • Special needs (high efficiency, high homogeneity, AR coating)
  • Quantity for samples and serial production
