Image Intensifiers
Unfilmed
In 2010, L3 released the first filmless tubes (without an ion barrier film). Over the years, continual improvements to the technology were made, extending reliability and increasing performance, while producing at an ever increasing consistency.
L3 Unfilmed image intensifiers, as of today, outperform all other tubes by a considerable margin, with exceptional performance even in very low ambient light conditions, often exceeding an SNR of 30 and reaching a FOM of up to 3000.
Due to patents L3 is currently the only company producing filmless image intensifier tubes. [1]
