For research applications, the Laser µFAB tabletop laser micro-fabrication workstation is viable for use in both additive and subtractive processes. These include 3D micro fabrication by two-photon polymerization (TPP), laser ablation and surface structuring of various materials, volumetric writing of waveguides and microfluidics, nano surgery, and micro dissection. The station is configurable for use with femto-second laser oscillators, amplifiers, OPAs, and other types of lasers in the visible to near-infrared range. Computer-controlled variable attenuation is on tap to prevent over or under exposure at the sample. The standard Laser µFAB includes stages covering 100-mm X and Y and 4.8-mm Z with a resolution of 50 nm. The top plate includes a holder with features for slides, cover slips, wafers, or large samples. NEWPORT CORP., Irvine, CA. (800) 222-6440.
