RP2 Measuring Head
To access the mirror and the opto-electronic
components, remove the optical assembly from
the measuring head. The two red dots indicate
where the measuring head and optical assem-
bly will separate. When reassembling the
measuring head after cleaning make sure the
two red dots align as shown in the picture.
To remove the optical assembly, pull the two
halves of the measuring head apart. The loose
half is the optical assembly containing the light
emitting and light sensing opto-electronic ele-
ments and gold contacts. The other half con-
tains the mirror, temperature sensor, and some
mating gold contacts. Avoid touching the mirror
and gold contacts with your fingers to prevent
contamination.
Clean the mirror with a clean cotton swab or a
lint free tissue.
Never attempt to polish the mirror.
If necessary clean the mirror with
methanol or alcohol. Then clean
the mirror with distilled water to
ensure the cleaning chemicals are completely
removed from the mirror surface.

Front Panel
The 473 front panel is completely sealed and can easily be cleaned with liquid glass cleaner or other
mild cleaning chemicals applied to a cloth. Clean the front panel periodically as needed.
