IRISS National Distributor * Infrared Windows for All Electrical Safety Applications
The IRISS VPFC (Viewing Pane Fixed Crystal)
ranges of IR windows are our crystal based Viewing Panes. The
VPFC range utilizes Calcium Fluoride as the standard lens,
however we also offer Germanium, Zinc Selenide, Sapphire and
other more specialized materials as lens materials; the choice
of material required will depend on the application.

Use
These have been subjected to the UL 508 test,
and the body assemblies are UL94 5VA flammability rated.
However the crystals we use for the infrared lens are 3mm
thick and currently exempt impact and flammability testing and
are not required to be subjected to the UL746c tests, and as
such do not have the strength of our VPFR range of IR windows.
See the Impact
Test Video.

Important Safety Note:
Due to the
material limitations associated with crystals this range is
not really considered suitable for Industrial applications.
This is primarily due to the fact that no crystal IR viewing
pane lens can meet the mandatory impact and load tests
required by IEEE for viewing panes fitted to electrical
switchgear.
