Direct Laser Writers

grating 3d4PICOs' line of Direct Laser Writers are used for a broad range of applications. The PicoMaster 200 has a strong base in the security label industry due to its abilities to write gratings with features down to 300nm on pasport size substrates while the PicoMaster 100 is an excellent and afforable R&D machine for substrates upto 4". With it's unrivaled optical properties, grayscale exposure and flexible software the PicoMaster is a high precision and versatile tool.

With the PicoMaster 200 Direct Laser Writer, custom designed micro- and nano-structures can be written directly in a photosensitive film on a flat substrate. The PicoMaster 200 is designed to be fast, flexible and cost efficient. The device can write structures as small as 220 nm. As this is our newest generation of direct laser writing equipment, it incorporates grayscale writing capabilities for mastering 3d-structures as well. The PicoMaster 200 Direct Laser Writer comes with an easy to operate software library and is compatible with the glass preparation unit PicoMaster Preprep P200.

Application areas: R&D, micro fluidics, optics, MEMS masks.

Direct Laser Writer 4P C200 (cylindrical substrate)

A laser writer for writing on cylindrical substrates, the 4P C200, is currently under development. In order to replicate a large amount of micro-structures, roll-to-roll systems can be used to duplicate micro-structures in a continuous way. In these roll-to-roll systems, a master shim is usually wrapped around a drum. The use of such shims naturally leads to seams in the result. 4Pico is designing a direct laser writer that can create a seamless cylindrical mold with a pattern of micro structures. These cylindrical molds enable the reproduction of micro structures without seams. Applications areas for writing on cylindrical molds include, among others: micro fluidics, optics, MEMS, roll-to-roll systems, masks and holographic labeling structures.
