wavemeter ws8

Unrivaled Precision

The HighFinesse/Ångstrom WS8 is worldwide the most accurate instrument for wavelength measurement of pulsed or continuous laser sources.
By developing novel optics and software specifically adapted to photonic crystal fibers with endlessly singlemode operation, the WS8 can now measure the whole sensor range (330 – 1180 nm or 630 – 1750 nm) at ultra-high wavelength accuracy (< 2 × 10-8). With each device an optical multichannel switch is included. This allows the user to simultaneously measure and control several lasers at any wavelengths within the complete sensor range of the wavemeter.
The WS8-series delivers unsurpassed absolute and relative accuracy supporting cutting-edge scientific research, as well as industrial and medical applications.
