Service

In normal operation the WFS series Wavefront Sensors does not need any service. It

is recommended to screw on the dust cover when the Wavefront sensor is not used.

Remove dust in the instruments entrance aperture with oil-free compressed air.

There is no need to recalibrate the WFS series Wavefront Sensors after a period of

time.

Troubleshooting

1. No Wavefront Sensor found after start of wfs.exe

Look if the Wavefront Sensor is connected to the USB 2.0 port of the PC by

the delivered USB 2.0 cable. The LED at the back of the Wavefront Sensor

will indicate the instrument state:

- LED = off USB cable or USB port is defect

- LED = red Sensor not recognized by the Windows system, install the

Wavefront Sensor drivers (see Software Installation )

- LED = green Wavefront Sensor is properly installed an can be used by the

application program

Did you complete installation from the Wavefront Sensor Installation CD?

NOTE

If you connected the Wavefront Sensor to another USB port of the PC as you

did during installation process you have to enable this USB port for Wavefront

Sensor, too. If so, wait a few seconds until the new hardware (for this port) was

found and the popup window occurs and look at Connection to the PC .

Be sure to have administrative rights on your computer which enables you to

install software at all. Ask your system administrator to give you such rights or

to do the installation himself.

Click 'Refresh' button on the 'Select Instrument' popup window. The system

needs a few seconds from connecting the device to make it ready to use.
