More Structural Integrity: The XIR series IR Windows were designed to be stronger that the enclosure you will attach it to so that if there was ever an arc event, the enclosure would fail the way it was designed to fail (or in the case of Arc Resistant enclosures, the enclosure would contain and redirect the blast as designed). Compare our construction to any other offering and see if you agree that Exiscan™ is uniquely robust.

• Cover and base anodized and powder coated for belt-and-suspenders protection from the elements
• Hinged cover with captive, spring loaded1/4-20 screws
• UL Type 4 / 4X recognized, and IP65 certified for indoor and outdoor use in the most aggressive environments
• All stainless steel hardware
• Stainless steel reinforcing plate to spread load and flatten mount even under intense pressure
• Impact resistant optic
• Polymer optic will hold mechanical integrity and transmission characteristics even under prolonged environmental exposure

More Field of View: Exiscan's™ unique square 4"x4" (100mm x 100mm) aperture will not "crop" your image on your camera's squared display even when shooting at steep angles. Smaller windows and round windows were originally fine when research laboratories would shoot straight ahead, but industrial thermographers shoot through windows at angles.

Exiscan's™ polymer optic also allows the thermographer to place his lens directly against the optic, thereby delivering a fuller view. Imagine watching a ball game through a knothole in a fence – are you going to stay 2" back from the fence (as required when using antiquated crystal windows)? Or are you going to put your eye right up to the hole to see the entire game?

More Accuracy: Exiscan's^TM optic transmits at roughly 66% throughout the mid-wave (MWIR: 3-5µm) and long wave infrared spectrum (LWIR: 8-14µm). Because of the relatively stable transmission rate across the spectrum, users can expect accurate temperature calculations, within +/-3 to 5%.

Conversely Calcium Fluoride (CaF2) crystals, are great transmitters in the MWIR, and were therefore very accurate when the industry used MWIR cameras. However, all of today's industrial cameras use LWIR technology, and by crystal window manufacturers'  own admission in technical papers, crystal windows are inherently inaccurate when paired with today's standard long wave imagers:

Compliance: Comply with insurance mandates to perform annual infrared inspections, while also complying with the regulations imposed by NFPA 70E and CSA Z462. The de-risked work process of using an IR Window eliminates the high-risk tasks (opening the enclosures) associated with typical infrared inspections. As a result elevated levels of PPE are not required, and complying with the standards is automatic.

Inspect the Un-Inspectable: After completing arc flash surveys / incident energy analyses, many facilities discover that some percentage of their equipment has extraordinary incident energy levels (per ANSI/IEEE 1584 or similar calculations). Such equipment receives a "Dangerous" label, and becomes off limits to thermographers. IR windows allow the thermographers to still survey desired targets in "Dangerous equipment" (through the IR window) while equipment remains closed and guarded in compliance with standards like NFPA 70E and CSA Z462.

Ease of Inspection: Imagine the benefits of monitoring hyper-critical applications and "bad actors" more frequently using IR windows. In just a few minutes, without requiring elaborate PPE or work processes, thermographers will troubleshoot and inspect critical electrical equipment through the specially designed IR window optic, thereby eliminating inherently risky and time-consuming tasks. The ease of inspection provides facilities with the latitude to inspect more frequently to ensure maximum facility up time.

Data Quality: Industry best-practices and standards (including NFPA 70B) note that IR scans must be performed when conductors are fully loaded (or as close as possible). Yet on inspection day(s) it is quite common that at least some percentage of equipment is unloaded or lightly loaded. Consequently, data is gathered and analyzed under conditions that could easily yield false-negative results. The ease, safety and speed of inspecting through an IR window means that thermographers can schedule inspections on days and hours when equipment is "running all out" – the best time to gather data.

Another factor to consider is that open-panel inspections, by their nature, introduce the possibility of many variables for reflected energy (off highly reflective metallic components. Less experienced thermographers could easily misinterpret theses these reflections from hot or cold elements in the background, resulting in false-positive and false-negative reports. Because the closed doors and panels of the enclosure are a relatively uniform ambient temperature, actual differences in temperature are more easily identified.

De-Risked Work Process: Open-panel inspections are, by their nature, high risk because they introduce a host of potential variables: stirring dust, agitating a conductor or misplaced tool, scaring a rodent, possibly dropping parts into the enclosure, etc. Infrared windows maintain an enclosed and guarded state (per the standards) and remove the high-risk work tasks, thereby reducing the risk of performing thermography through an IR window. The new closed-panel work task does not expose personnel to energized conductors, and is not a task that could trigger an arc. As such, using an IR window is similar to looking in a visual inspection window {Link visual inspection window to our page for same}, reading a panel meter, or simply walking past the same equipment. Facility managers can take comfort in knowing that the new closed-panel is de-risking their inspection process. No longer does an IR inspection represent a threat of a catastrophic outage.

Why Polymer? Exiscan^TM designed it’s IR windows for the industrial electrical market. With this in mind, traditional laboratory crystals were not an option.  After extensive testing and research, we saw that only polymer satisfies the most important demands of the industrial market:

• Durability: Industrial electrical equipment requires impact resistant optics
• Longevity: Transmission characteristics must be resistant to humidity, moisture, chemicals
• Accuracy: Accurate Temperatures and ΔTs require an optic that transmits the entire LWIR spectrum
• Large Field of View: Larger, square windows allow Thermographers to evaluate more with less
• Value: Closed-panel inspection is safe and efficient, but industry requires affordable solutions

XIR Infrared Windows with patent-pending polymer infrared optic is uniquely suited for industrial and facilities maintenance environments: Built like a tank, resilient and warranted for life, accurate and compatible with all models of cameras, big enough to see it all with fewer windows, yet surprisingly affordable.

Exiscan^TM won’t compromise on safety, accuracy or usability. That’s why we over-engineer our design and only use industrial-grade materials - like polymer, aluminum and stainless steel.

Infrared (IR) Window

• Square IR window optic provides best in class field of view, with 28% to 65% more optic area than similar sized round windows.
• Square format yields superior field of view. When images are taken at broad angles through the window, the square aperture matches the camera’s squared display resulting in little to no cropping.
• Impact-resistant optic for unsurpassed durability.
• User get’s full field of view by placing camera lens on the window optic.
• Polymer optic is inherently resistant to moisture, humidity, broad spectrum of acids and alkalis for longevity and stable transmission.
• Transmission throughout the entire long wave and mid wave IR spectra for accurate temperate and ΔT calculations.
• Fail safe stainless steel finger guard.
