WS/7 Super Precision
Wavelength measurements with highest accuracy
The WS/7 Wavemeter 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.
 Standard measurement range 350-1120 nm
Relative accuracy 10-7
Measurement speed 150 Hz (Data collection 400 Hz)
Capable of measuring cw and pulsed lasers
Various options available
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 WS/7 Wavemeter permits the integration of additional optical components and software modules, allowing custom
solutions for customer specific application even years after purchase.

| Warm-up time |
No warm-up time under constant ambient conditions (except IR-II: >30 minutes warm-up time required) Otherw. until thermal and air pressure equilibrium is reached. |

| Interface |
High-speed USB 2.0 connection |
| Power supply |
Power consumption <2.3 W, supply directly via USB cable, IR-II: external power supply included; IR-I and WSU via USB or external power supply possible |
| (1) With multi mode fiber |
|
(2) Values for wide-/fine-mode |
|
(3) Only for standard range |
| (4) But not better than 5% of the linewidth |
|
(5) According 3σ criteria |
|
(6) Without autocalibration usage |
| (7) The cw power interpretation in [µW] compares to an exposure of 1s (generally the energy needs to be divided by the exposure time to obtain the required power) |
|
(8) [µJ] interpretation for pulsed lasers; cw signals need more power in [µW] since the exposure is limited at IR-II devices |
|
(9) Not IR devices, external calibration source needed, e.g. SLR-1532 |
