risk prevents it. But they do so at their peril as a failure in these systems could be the most costly of all. The greatest spur to the take-up of IRISS windows
is however the technology itself. Although infrared windows have been available for many years, their design and scope of application has been substantially limited by their material of manufacture, fluoride crystal. Firstly this type of window carries the significant risk of breakage, especially in the presence of vibration. Even an electrician slamming an enclosure door can cause it to shatter. This presents manufacturers, particularly those in the food and pharmaceutical sectors, with a problem. In an attempt to prolong the life of crystal windows,
many are coated, but if this coating does not cover all facets, including the edges, water ingress will eventually shorten their life considerably. During this phase of degradation, their transmission value also changes making readings taken inaccurate unless the operator constantly ensures the camera is calibrated properly. Of course, each crystal window can degrade at different rates. They are also susceptible to UV damage that results in them becoming opaque, ineffective and unsafe. And then there’s the problem of size. A 4-inch diameter is the absolute maximum for these products and when it comes to shape, the only choice is round. So what makes IRISS different? IRISS uses
patented polymer material that makes its products the world’s only industrial grade windows. Reinforced by an aluminium honeycomb grill, they carry an unconditional lifetime warranty against breakage and are not degraded by acids, alkalis, UV, moisture, humidity, vibration or high frequency noise. IRISS windows can also be configured to virtually
any shape or size, a capability that is not achievable with crystal technology. For example, the window can be supplied to allow the inspection of an entire bus bar or multiple components in a single pass of the camera. Originally IRISS windows were only available in
opaque polymer but that changed with the introduction of Platinum. The capabilities of this range are made possible by the IRISS Poly-View System patented clear polymer. It effectively removes the only benefit that a crystal window could claim over the opaque IRISS alternative - the ability to allow visual inspection. Platinum is now the only window available for
inspection in the UV and visual as well as all three infrared spectrums. It can be used in conjunction with any brand of thermal imaging camera, assuring a fixed and stable transmission rate for quantitative and qualitative analysis.
Any shape, any size
While safe thermal inspection of live electrical systems is one of the most common applications for the IRISS
