WSU Ultimate Precision

 Standard measurement range 350-1120 nm
 Relative accuracy up to 10-8
 Measurement speed 200 Hz
 Capable of measuring cw and pulsed lasers
 Various options available

The WSU-Standard 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 WSU-Standard is connected to the PC via the USB interface. After installing the software delivered with the wavemeter, the device is ready for measurements. There is no warm-up time under constant ambient conditions.

Guaranteed Future

The design of the WSU-Standard permits the integration of additional optical components and software modules, allowing custom solutions for customer specific application even years after purchase.
For further particulars on the available options we refer you to our options page.
