Overview
The Spectra-Physics Vanguard One UV125 is a compact, all-in-one, mode-locked quasi-CW laser delivering more than 125 mW of UV power at 355 nm. The laser operates air-cooled with low noise of less than 1% rms and delivers a long operating life with low cost of ownership. Vanguard One is ideal for bio-instrumentation applications, including flow cytometry, cell sorting, wafer inspection, electron microscopy, confocal microscopy, and laser-induced fluorescence.
Designed for 24/7 Applications
Vanguard One operates air-cooled with low noise of less than 1% rms and delivers a long operating life and low cost of ownership for bio-instrumentation applications such as flow cytometry, microscopy, cell sorting, and semiconductor wafer inspection.
All-in-One Design
Vanguard One combines electronics, laser cavity, and cooling in a single housing, and its closed-loop power control keeps power variation below 2% for consistent, long-term measurement results.
