New UV laser targets microscopy & semiconductor wafer inspection

Vanguard One UV125

MKS Instruments has launched the Spectra-Physics Vanguard One UV125, a compact, all-in-one, quasi-CW laser delivering >125mW of UV power.

The new laser operates air-cooled with low noise of <1% rms and delivers long-operating life and low cost of ownership. Vanguard One is ideal for applications in bio-instrumentation including flow cytometry, microscopy, and cell sorting, as well as semiconductor wafer inspection.

The ‘all-in-one’ laser combines its electronics, laser cavity, and cooling in a single housing for ease of integration and bench-top tools. Its quasi-CW operation ensures high fluorescence signal-to-noise ratio while preventing damage to cells in bio-instrumentation. 

The laser firmware enables closed-loop power control, ensuring long-term stability with less than 2% power variation for consistent measurement results. Vanguard One lasers pass extensive environmental qualification testing to deliver high reliability and low cost-of-ownership needed for bio-instrumentation and demanding industrial applications.
