Excimer laser micro machining using image projection technique allows removing consistent volume of material per each laser pulse.
Due to the consistent area of the image, it allows controlled removal of material to a required depth.
Combination of consistent material removal with additional techniques, like material drag and coordinated motion, allows creating three-dimensional structures in wide range of materials.
It can also be performed on practically any shape of material: flat, cylindrical, conical or spherical.

Applications:
Applications include machining lubrication or air channels in bearings, machining variable shape nozzles for ink jet devices, machining channels, reservoirs and elements for micro-fluidic, bio-medical, MEMC and photonic devices.

Materials:
Type of material determines optimum energy density and size of the area machined with single exposure. Material shape and 3D pattern geometry determines how many axes of motion should be involved in creating a pattern.
|
|
|
Machine Type:
LLTI micro machining systems have multiple axes of controlled motion to perform machining to each demanding application. Vision systems with image recognition assure consistent quality of machined products.
