Click here to download PDF version of this page.
Used for ATR (attenuated total reflection) prisms, infrared windows and
lenses from 0.6-40 microns. KRS-5 is only slightly soluble in water but
can be attacked by some solvents and acids. This material is relatively
soft and care should be taken during handling and processing.
Caution: Thallium compounds are classified as toxic and must be
handled with care.
