【1】General Handling
All the《EVER-COLORS》should be handled with the special care as same as
forprecise optical glass elements like lenses, prism, mirror, etc. employed
in various
fine optical instruments.
【2】 Durability
A piece of《EVER-WHITE》No.9582 which had been stored for more than eight
years in the original case at room temperature with average relative humidity
of 60%,
and it was confirmed that the piece did show any practical change in its
charateristcs
of reflectance and other properties [1].
However, as a rule, use and keep《EVER-COLORS》 in the neutral dry atmosphere
for regular measurements.
【3】Cleaning Surface
For the polished optical flat surface most of the reliable cleaning agents
and wiping
fabrics specially woven are available not only for optical glass but also
for《EVER-
COLORS》,However, before applying these procedure, surface dust must be removed
thoroughly by browing or washing lest give any scratches on the surface.
Howadays, new types of disposable texture for the purpose have been developed by
some of polymer-fiber makers in Japan.
For cleaning ground (mat) surface, ultrasonic cleaner can be used with
neutral pH
media, following thorough rinse to remove residual media.
【4】Environmental
Temperature
Data of the reflectance and chromaticity characteristics have been obtained at room
temperature, therefore, avoid using《EVER-COLORS》under such harsh conditions
as in which sudden change of temperature and uneven thermal distribution
may occur.
