Laser Optical Engineering has extensive experience and knowledge in the production of highly efficient DOEs, known as kinoforms, for high power laser applications. These elements can be designed to generate laser intensity profiles that cannot be achieved using conventional lenses and mirrors.
Diffractive Optical Elements (DOEs) are computer-generated holographic devices that can be used for laser beam shaping. They have applications in glass cutting, plastics processing, laser hardening, laser soldering, welding and laser surgery.
The use of DOEs:
- enable you to overcome the limitations of current refractive and reflective beam shaping devices
- greatly enhance processing characteristics and efficiency, allowing the realisation of novel applications
LOE can produce DOEs to your specification for both standard and complex laser applications. Alternatively, we offer a unique design service to meet your application needs.
DOEs can be used to transform high powered laser beams into virtually any shape and is a unique service offered by LOE.
Thermal models, developed at LOE, are utilised to design optimised beam shapes which can achieve superior performance and realise processing characteristics unattainable using conventional optics.
DOEs have been successfully used in the following applications:
- Simultaneous soldering of multiple connections on circuit boards, by use of beam splitting optics
- Multiple point simultaneous drilling
- High performance glass cutting using a line intensity distribution
- Single shot component marking/branding by use of diffractively shaped character sets
- Simultaneous production of a weld and a cut for the manufacture of plastic bags
- Production of variable depth, controlled hardening on gear teeth in a single laser shot
- Laser curing of protective coatings using an even intensity distribution generated by a diffractive
