Photo Tube (UV Lens)

High sensitivity and high stability: High sensitivity and high stability make phototubes very useful in chemical and medical analytical instruments which require high reliability.
 
Wide dynamic range: Phototubes feature a wide dynamic range from several picoamperes to several microamperes, providing signal output with excellent linearity
 
Superior temperature stability: Phototubes show virtually no fluctuation with changes in the ambient temperature.
 
Large photosensitive area: ompared to semiconductor sensors, phototubes offer larger photosensitive area.
 
Low voltage operation: Phototubes are designed to operate at a low voltage.
