- Model Analyte Excite+ - Homogenized Excimer Laser Ablation System

From

0

The Analyte Excite+ is the ultimate excimer based laser ablation system. It utilizes the latest, highly developed iteration of ATL’s solid-state switched laser engine and includes the acclaimed HelEx II Active 2-Volume Ablation Cell and its unique adaptive inner cell. The system delivers finely controlled flat (homogenized) ablations with high sensitivity and split-second response for shot-to-shot spatially resolved analyses. Stage-synchronized “fire-on-the-fly” lasing provides depth profiling of lines and raster areas like never before. Energy density from 1 J/cm2 to 15 J/cm2 ablates all materials.

The Excite+ also comes fully equipped with the ARIS fast washout accessory, eQC and ExiCheck to allow the best possible performance and flexibility of any excimer-based laser system on the market today. In addition the Analyte Excite+ also has a software controlled integrated Demag switch that allows the selection of 64 spot sizes from 1 μm to 245 μm as a standard feature. All spots are achieved with aperture imaging of the beam to ensure energy densities always remain constant when changing spot sizes.

A complete system comprised of:

  • Analyte Excite Laser Ablation System
  • HelEx II Sample Cell
  • ARIS Fast Washout Accessory
  • eQC Energy Monitoring
  • ExiCheck Gas Exchanger

Using a proprietary component to enable maximum beam homogenization the Analyte Excite system is able to generate beautiful flat bottomed craters with sharp edges and with no visible melting. The 50 μm circle (left) is the result of 10 ablation shots, and the 80 μm square (right) is from a 25 shot ablation.
