VPFC SeriesCalcium Fluoride (CaF2) has long been used in research applications. It performs best in controlled environments where humidity, chemical exposure, vibration and high frequency noise are minimized or eliminated. The transmission rate characteristics of CaF2 are suitable for higher temperature applications, shortwave and midwave thermography and for the visual spectrum. Medium to longwave transmission rates (7-14 micron) are typically between 40-50% based on the infrared (IR) camera detector sensitivities at different wavelengths. VPFC Series (Viewing Pane Fixed Crystal) IR windows are specially coated to reduce the transmission drift due to moisture/humidity. However, industrial users are strongly encouraged to investigate the VPT Series of industrial-grade IR windows which are specifically designed for stability in harsh industrial environments and have an unconditional lifetime warranty. When purchasing crystal windows, ask for the Material Safety Data Sheet (MSDS) to ensure that the crystal does not contain hazardous substances. Some window manufacturers use crystals made of Barium Flouride (BaF2), a toxic substance, especially hazardous to the food and beverage industry.
VPFC Series is crystal infrared windows for short, mid, and long wave and visual inspections.

Tested and Certified to The Highest Industry Standards
IRISS IR windows are the most certified windows in the industry with IEEE (impact & load), UL, cUL, Lloyds and CSA C22.2 14-13 for industrial control equipment Check out this product certifications!
UL 50V applies to infrared windows and is more of a classification than a standard that applies for performance-of-build characteristics.
CSA C22.2 No. 14-10
Canadian Standards Association shows that a product has been independently tested and certified to meet recognizable standards for safety and performance.
UL 508 & 508A
UL 508 and UL 508A are classification for the components used on electrical panels. UL 746C is a standard requiring flammability and impact tests for polymeric materials used on electrical equipment.
These equivalent ratings certify enclosures for indoor or outdoor use. They protect against access to hazardous parts, ingress of foreign objects and water from rain, sleet, snow, splashing or hose directed water & ice formation damage.
UL 50E standard applies to enclosures for electrical equipment intended to be installed and used in non-hazardous locations.
Lloyd’s of London
Lloyd’s provides independent, third-party approval certificates attesting to a product’s conformity with specific standards or specifications. It verifies the manufacturer’s production quality systems through a combination of design reviews and type testing.
Requirement covers metal-enclosed, low-voltage power circuit breaker switchgear assemblies containing but not limited to low-voltage power circuit breakers, switches, control, instrumentation and metering, protective and regulating equipment.
American Burea of Shipping
An ABS assessment is the pre-approval of a product for use on a variety of ABS- classed ships following a technical evaluation. Ship designers, builders and owners can select the product to be placed aboard and ABS-classed vessel.
Sets the impact & flammability standards for polymer materials used in electrical equipment to 1500 volts. Plastic/polymer parts of an IR window must pass flammability tests at room temperature & remain intact during an impact test performed at 0°C (32°F).
IEC Vibration & Humidity
Certified IRISS IR Windows experienced no obvious signs of damage due to vibration or extream humidity when put under IEC testing conditions for IEC 60068-2-6, 60068-2-3, and 60068-2-78.
DNV Certification is awarded for marine and offshore applications and allows preventative maintenance on electrical equipment in these vertical markets. DNV covers Rules for Classification of Ships and Offshore Standards (vessels, tankers, military and cruise ships, and oil drilling riggs).
IEEE C37 20.2a.3.6
The IEEE C37 20.2 Section 3.6 is the impact and load requirement for all viewing panes installed on medium and high voltage switchgear. Panes made from crystal of glass will not pass these requirements.
