Mirror and Lens Cleaning

The mirrors and lenses of the LIO headpiece and Slit Lamp adaptation must be

kept clean and unscratched. Cleaning them requires special care and the following

materials:

• Standard lens cleaning paper

• Methanol of spectrographic quality.

The following tips will aid you in cleaning the optics:

• Use each piece of cleaning paper only once.

• Move the cleaning paper across the optic surface from one end to the other in one

continuous motion. Discard the cleaning paper and use a new piece for the next cleaning

pass.

• Do not use a back and forth rubbing motion on the optic surface.

CAUTION

Care and cleaning operations must be performed with the instrument turned off and

power cord disconnected. Use only optical quality paper and spectroscopic quality

methanol when cleaning the mirrors and lenses, otherwise the optics could be

scratched and their coatings destroyed.
