Freeform Optics

Tool Making

Tools are designed and manufactured in house. Also mould validation and volume production can be done in-house. Mould inserts are typically produced by diamond machining, micro milling an polishing.  A roughness of 30nm Ra can be achieved by micro milling and 5nm Ra by polishing.

Injection Moulding

For the replication of freeform optics two in-house moulding methods can be used:

  • Injection compression moulding
  • (Vario Thermal) straight injection moulding

Depending on your product, we will select the favourable method for you.

QA

For measurement of the mould insert and/or replica’s we use either an 3D confocal Laser Microscope, surface profiler or a CMM using a probe and freeform software.
