Precautions
Mirrors
In order to provide the maximum transmission in the infrared, with the minimum spectral interferences,
the mirrors used in this device are uncoated (bare) aluminum on a glass substrate. Since the coatings are
soft, care must be taken to avoid damage. Normally, these mirrors will not need cleaning, since they are
contained within the housing of the accessory. If they do need cleaning, they may be gently wiped with
a lint-free, abrasive-free cloth, such as lens tissue, or with a camel hairbrush. Under no circumstances
should the mirrors be rubbed with paper products such as “Kleenex” since this will scratch the mirror
surface resulting in reduced IR throughput.
SAFETY
Caution should be used when handling and using ATR crystals since some of the materials can be
hazardous. Specifically, zinc selenide is a heavy metal material and should be handled with this in mind.
If the crystal is broken or pulverized, the dust may be harmful by inhalation, ingestion or skin
absorption.
