screen is almost clean from random background.
Below is an example with Ofil's laboratory corona generator. The corona is in the

When operating in the LI mode the UV channel of the DayCor® Superb camera turns

image will be smeared. When recording while operating in the LI mode, the camera
should preferably be used from a tripod, or the operator should be able to hold the
camera without moving it
