The UV Power Puck is a self-contained, electro-optic instrument designed to measure and display peak UV irradiance and total UV energy density used in the UV curing process. The Power Puck's unique compact design, only 4.60 inches in diameter and 1/2 inch high, allows it to be placed directly in most curing environments. The instrument operates successfully in the extremes of UV and thermal radiation often encountered in UV curing systems.

A carefully designed optical sensing system measures total UV dosage on 4 different channels simultaneously. These four different channels represent four different UV bandwidths of interest for most curing applications: UVA (320-390nm),UVB (280-320nm),UVC (250-260nm) and UVV (395-445nm). The output of the sensing system is converted to digital form and displayed on the LCD by scrolling through a user-friendly menu. Total UV dosage, measured in Joules/cm2, is the result of the integrated irradiance during exposure time. It is how much actual UV energy was impinged on the unit from the time it encountered UV until the time the UV source was removed.

The UV Power Puck also has the distinct advantage of being the only radiometer able to monitor the peak irradiance in Watts/cm2 in each bandwidth. This allows the operator to determine not only the total energy density, but also how that energy density is delivered; i.e., what irradiance at what wavelength.
