WS Ultimate Precision

Wavelength measurements with highest accuracy

 Standard measurement range 350-1120 nm
 Relative accuracy up to 10^-8
 Measurement speed 150 Hz (Data collection 400 Hz)
 Capable of measuring cw and pulsed lasers
 Various options available

The WS Ultimate is a sensitive and compact wavelength meter for laser sources. It is capable of measuring pulsed and continuous laser sources. Both, optical elements and assigned electronics are housed in a compact, thermally isolated casing.

Easy Set-up

The wavelength meter is connected to the PC via the USB interface. After installation of the supplied software, the device directly is ready for measurement.

Guaranteed Future

The design of the wavelength meter "WS Ultimate" permits the integration of additional optical components and software modules, allowing custom solutions for customer specific application even years after purchase.
