The tube types below are available in green or white phosphor and thin or un-filmed. Each tube is rated by FOM or Figure of Merit. This number is calculated by multiplying the Signal to Noise ratio by the resolution of an image intensifier. The FOM number allows a quick estimate of the general performance level of that tube. Every order will come with a spec sheet that states that tube’s characteristics and its compliance with advertised specs.

IMAGE INTENSIFERS

Gen I

Gen I: Developed in the 1960s, it uses a three-stage cascaded fiber optic coupling structure. It is large and heavy, lacks a microchannel plate (MCP), has image distortion of 15%-25%, is sensitive to strong light, easily damaged, and has poor resistance to strong light. It utilizes basic principles to amplify existing light thousands of times, allowing you to see objects clearly in the dark. Typical performance of Gen I image intensifiers: brightness gain 2×10⁴-3×10⁴ cd/m²·lx⁻¹, resolution 35 lp/mm.

Gen II

Gen II: Gen II image intensifiers utilize both electrostatic focusing and proximity focusing structures. Image distortion is reduced to 2%-3%, brightness gain is approximately 5×10⁴ cd/m²·lx⁻¹ (18/18 tube type), and resolution is 30 lp/mm. Developed in the 1970s, Gen II offered a substantial increase in performance over Gen I systems. This performance enhancement was obtained by the addition of a micro-channel plate, commonly referred to as an MCP. The MCP works as an electron amplifier and is placed directly behind the photocathode. The MCP consists of millions of short parallel glass tubes. When the electrons pass through these short tubes, thousands more electrons are released. Gen II lifespan 2000 to 4000 hours.

Gen III

Gen III: Developed in the 1980s, it uses gallium arsenide (GaAs) photocathodes and anti-ion feedback film technology, increasing sensitivity by 4-8 times compared to Gen II image intensifiers (up to 1400 μA/lm), extending lifespan by 3 times, and achieving a resolution of 50 lp/mm. The manufacturing process is complex and costly, but the performance is significantly improved. This makes Gen III image intensifiers the highest-performing image intensifiers currently available. Gen III image intensifier systems have a lifespan exceeding 12,000 hours. The US military equipped this generation of products during the Gulf War, with more noticeable results.

Gen IV

Gen IV: Gen IV image intensifiers utilize the latest technology with film-less MCP and automatic pulsed gating power supply, significantly improving signal-to-noise ratio and resolution, resulting in clearer imaging and operation in a wider range of lighting conditions, but the technology is not yet fully widespread. Some companies are still attempting to use the "fourth generation" designation as a marketing tactic, selling products that are identical to Gen III image intensifiers offered by other manufacturers at significantly lower prices.
