The COMPACT DISC RADIOMETER (CDR) is a self-contained, electro-optic instrument designed to measure and display peak UV irradiance and total UV energy density applied to a workpiece in a UV curing system. The CDR has a unique compact design, only 120mm in diameter and 25mm high, which 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 energy density in a particular bandwidth. The output is converted to a digital form and then displayed on the LCD. Total UV energy density measured in joules/cm² is the result of the integrated irradiance during the 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 CDR also has the distinct advantage of being able to monitor the peak irradiance in watts/cm². This allows the operator to determine not only the total energy density, but also how that energy is delivered; i.e. at what irradiance level.
