- Model Excite Pharos - Femtosecond Laser Ablation System

From

0

The Excite Pharos is a the most user-friendly femtosecond laser ablation system on the market, featuring a compact, fully sealed and factory aligned laser head that does not need routine adjustment or cleaning. The system can be configured for 1028 nm, 257 nm or 206 nm, or configured for a switchable system if desired. An energy density of 10 J/cm2 (1028nm), 5 J/cm2 (257nm) and 3 J/cm2 (206nm) is achievable, with 0.1% RSD on shot-to-shot stability over long runs.

The Excite Pharos is available with the class leading HelEx II Active 2-Volume Ablation Cell, enabling 700 ms washout and a constant ablation environment. The ARIS fast washout accessory is also available to further improve analytical performance providing aerosol transport in the order of 30-50ms.
