Note: Both sides must be adjusted evenly.

Irradiance and Dose

Refer to your material manufacturers recommendations for UV irradiance and dose
requirements for your material.

•

Irradiance

: Irradiance is the intensity of the UV. The maximum irradiance is

achieved with the lamp assembly at 2.1 in (53.3 mm) from the target (see Section
14.2). Distances farther and closer will result in lower intensity.

•

Dose

: UV dose is a function of irradiance and time. Slowing down the conveyor

speed will increase time, therefore increase the total UV dose.
