Diffractive optical elements (DOEs)

Optical elements and units

Forming a smooth DOE structure with high-level gradation enables the production of high-efficiency, low-noise DOEs.
Application of our proprietary high-durability AR coat allows the use of DOEs for laser processing in combination with high-power fiber lasers.


  • High efficiency, low noise intensity
  • Excellent uniformity of spot intensity
  • Low zero-order light intensity
  • Compatibility with high-power fiber lasers


  • High-power laser machining (enhancement of welding/cutting quality)
  • Soldering
  • Light sources for special sensors
  • Improvement of machining efficiency by enabling multipoint lasers
  • Laser tempering, surface finishing
