Products - VPFC Infrared Viewing Panes - Total Engineering Solutions | Thermographic Surveys | Predictive Thermography Technology

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.

Impact Test Showing Fragility of Crystal Window

VPFC Infrared Window in 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.

Features of the IRISS VPFC Range of Viewing Panes:

	UL94 5VA Flammability Rated Assembly
	IP65 / NEMA 4 Rated Both Open & Closed
	5 types of IR viewing materials available catering to any environmental, operational or budgetary requirement
	Available in 2, 3 & 4 Inch Viewing Diameters
	Allows Safe Thermal Imaging of Fully Energized Electrical Components Through Closed Doors
	Suitable For Use With ALL Makes of Infra Red Cameras
	Manufactured Using Non Conductive Materials
	Simple Installation in 10 Minutes

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.
