How to clean metal filters or
attenuator gratings
This kind of device is extremely fragile. A misalignment of the grating
leads to inaccurate measurements. Never touch the surface of the
metal filter or attenuator grating. Be very careful when using or
cleaning these devices. Do not use cotton-swabs or soft-tissues, as
there is the danger that you cannot remove the lint and that the device
will be destroyed by becoming mechanically distorted.
Use the following procedure on most occasions.
1 Use compressed air at a distance and with low pressure to remove
any dust or lint.
Do not use an ultrasonic bath as this can damage your device.
Use this procedure particularly when there is greasy dirt on the
device:
1 Put the optical device into a bath of isopropyl alcohol, and wait at
least 10 minutes.
2 Remove the fluid using compressed air at some distance and with
low pressure. If there are any streaks or drying stains on the
surface, repeat the whole cleaning procedure.
