IRISS INFRARED SOLUTIONS
Engineered for Reliability.
Designed for Safety.
The world’s most advanced infrared windows, delivering clarity, durability, and unparalleled accuracy.
Why should you choose IRISS Infrared Windows?
PEOPLE FIRST
Inspections that keep people out of harm's way
Every IRISS infrared window is designed with one priority: keeping your team safe. By enabling accurate diagnostics with panels closed, our windows eliminate unnecessary exposure to energized equipment and reduce arc flash risk on every inspection.

FAST TECHNOLOGY
Stable transmission. For life.
Our patented polymer optic delivers Fixed and Stable Transmission (FAST), meaning your thermal readings stay accurate from the first inspection to the last. Unlike crystal alternatives that degrade, cloud, or absorb moisture over time, IRISS windows perform exactly as specified across the life of your asset.

BUILT TO LAST
The only window with an unconditional lifetime warranty
IRISS infrared windows are arc flash rated, seismic tested, and UL listed as standard. They’re engineered to withstand the realities of heavy industry and backed by the only unconditional lifetime warranty in the sector. No conditions. No small print.

S.M.A.R.T. TRAINING
Training that transforms careers and cultures
Our flexible, CEU-accredited S.M.A.R.T. Training programs give your team the skills to get the most from every inspection. From Cat 1 to Cat 3, we build technical confidence and a safety-first mindset that stays long after the course ends.

SUSTAINABILITY
Longer asset life. Less waste. Smarter operations.
By enabling regular, safe inspections without equipment shutdown, IRISS windows help catch failures early, extend asset lifespan, and reduce the energy loss and material waste that come with unplanned downtime. Better reliability and better ESG outcomes from a single investment.

FlexIR solutions meet the stringent safety standards of NFPA 70E, CSA Z462, and UL, ensuring your facility stays compliant with electrical safety regulations while maintaining operational efficiency.
Proudly Made in the United States
IRISS manufactures and assembles all FlexIR products at our global headquarters located in Bradenton, FL.
No Guesswork, No Compromise
FlexIR ensures a perfect fit for every window or panel, eliminating field modifications, saving time, reducing labor costs, and maximizing safety from day one.
FlexIR-Clear Infrared Window
The FlexIR-Clear range of products is another innovative addition to the custom solutions from IRISS to ensure that your inspection windows meet your needs and assist in your Reliability Program.
QwikFit-IR
The QwikFit-IR is a unique solution for panel board applications where a small-frame breaker’s load-side connections would not be visible for infrared inspection, even if a custom dead-front replacement panel had been installed.

Frequently asked questions about IRISS Infrared
What are IRISS infrared inspection windows, and why not just use a standard sight glass?
A standard sight glass is usually plain polycarbonate or acrylic — fine for a visual check, useless for thermal. Infrared windows use materials that pass long-wave infrared radiation, so a thermographer can shoot an accurate temperature reading through the window without opening the panel. IRISS windows go further: the same window supports infrared, visual, ultrasound, and partial discharge inspection, so one opening covers every diagnostic method your program uses.
How is this different from the crystal-based IR windows most manufacturers sell?
Most infrared windows on the market use a crystal optic — usually germanium or a similar material. Crystal is brittle, hygroscopic (it absorbs moisture over time, which degrades transmission), and limited to small round openings, typically no larger than 4 inches. IRISS uses a patented, reinforced polymer optic instead. It doesn’t crack under mechanical stress, doesn’t degrade from moisture or chemical exposure, and isn’t limited to a small round format — which is why IRISS can build windows in custom sizes and shapes.
What does "Fixed and Stable Transmission" (FAST) actually mean for my readings?
It means the window’s infrared transmission rate doesn’t drift over the life of the asset. Crystal windows lose clarity as they absorb moisture or develop microfractures, which means your thermal readings get less accurate over time even if nothing’s wrong with the equipment. FAST material holds its transmission rate, so a reading taken five years from now is as reliable as one taken on day one.
Can these windows handle harsh environments — outdoor substations, washdown areas, chemical exposure?
Yes. The polymer optic resists moisture absorption, chemical exposure, and mechanical stress, and the CAP-ENV series adds an environmental seal with an optional dust cover for extreme conditions. These are built for continuous outdoor and industrial exposure, not just clean indoor switchgear rooms.
Are they rated for arc flash environments?
Yes. IRISS windows are arc flash rated and arc containment tested to IEC 62271-200, and the product line is built to support NFPA 70E and CSA Z462 compliance. The entire point of an infrared window is to let your team inspect energized equipment without opening the enclosure — the arc flash rating is what makes that a real risk reduction, not just a convenience.
What inspection methods can I run through one window?
Depending on the series, a single IRISS window supports infrared thermography, visual inspection, ultrasound, and partial discharge detection. The CAP-CT-PDS, for example, covers thermal imaging, visual, UV, ultrasound, and PD in one opening. That means you’re not cutting a separate port for every inspection technology your reliability program uses.
What's the warranty, and what's actually covered?
IRISS backs its infrared windows with an unconditional lifetime warranty — the only one of its kind in the industry. It’s tied to the material itself not degrading, which is the whole argument for polymer over crystal: a window that doesn’t crack, cloud, or absorb moisture is one a manufacturer can actually stand behind for the life of your asset.
Can these be installed on existing equipment, or only in new builds?
Both. The CAP series and VP series are designed for retrofit onto existing switchgear, MCCs, and bus bar enclosures, and the Flex IR series offers fully customizable solutions for non-standard installations, including factory-fitted OEM panels for equipment manufacturers building inspection access in from the start.
How do I know which series is right for my application?
It comes down to what you’re inspecting and how. CAP is built for larger openings like bus bar compartments and multi-spectrum monitoring. VP is a smaller, round transparent format for standard panel inspection points, with ultrasound and thermographic variants. Flex IR is for anything non-standard — unusual geometries, OEM integration, or a combination of technologies in one custom port. IRISS’s team will typically size this to your equipment rather than making you pick blind from a spec sheet.
Where are these manufactured, and is there a quality/compliance angle to that?
IRISS infrared windows are conceived, designed, and built in the U.S., out of the company’s Bradenton, Florida headquarters, with global distribution from there. For buyers who need to document domestic sourcing for compliance or procurement reasons, that’s a straightforward answer rather than a supply chain question mark.
Our commitment to sustainability
We stopped whispering
about sustainability.
We fly hundreds of people across the globe to exchange information that could be delivered digitally. We build temporary structures designed to be thrown away. We measure success by badge scans and call it engagement. And we do it while talking about sustainability on panels and in annual reports.
The IRISS Sustainability Manifesto is our public declaration. The whitepaper is the proof. Together, they lay out the environmental cost of traditional engagement, the measurable alternative, and the framework we believe the entire industry can adopt.

Sustainability starts with safer maintenance
IRISS solutions extend equipment life, reduce energy loss, and prevent failures, helping you hit Environmental, Social, and Governance targets through safer, smarter operations.
Less waste.
More impact.
We’re rethinking our materials and methods starting with sustainable packaging that reduces plastic use and prioritizes recyclability. From product to delivery, we’re designing with the planet in mind.
Smarter connections. Lower emissions.
To reduce our carbon footprint, we’re cutting back on in-person events and investing in virtual training and digital collaboration. Because global reach doesn’t need to mean global travel.
