Abstract
A corona detection device includes a bandpass filter having a primary passband that includes at least wavelengths in the range of about 250 nm to about 400 nm and a secondary passband that includes wavelengths in the range of about 675 nm to about 850 nm. The corona detection device also includes an image intensifier in optical communication with the bandpass filter. The image intensifier is configured to generate an image based on radiation passed through the primary passband and the secondary passband of the bandpass filter.
