ATN Image Intensifier Tubes
Image Intensifier Tubes (IIT) are the core of any Night Vision device. Performance of an NVD is a direct result of the IIT quality. At ATN we offer the majority of our products with a wide array of IIT configurations to choose from. Image Intensifier performance is determined by two major parameters: Signal to Noise Ratio and Resolution. Here is a brief description of some of the types of IITs ATN uses. All of our IITs are of new production. We do not use used or refurbished IITs like some of our competitors. This even includes our standard 2nd Gen. IITs. |
2nd Gen + (2I) IIT
ATNs standard 2nd generation tubes are high quality with exceptional brightness and resolution. Each tube has a micro channel plate, multi-alkaline photocathode with built-in power supply |
2I IIT Features:
Photo Cathode type: Multi-Alkali
Resolution from 40 to 45 lp/mm
Signal-to-Noise Ratio from 14 to 18
5,000+ hour tube life |
2nd Gen + (2IA) IIT
ATNs 2nd generation + (2IA) tubes are high quality with exceptional brightness and resolution. Each tube has a micro channel plate, multi-alkaline photocathode with built-in power supply. The 2IA tubes are hand picked for additional performance with less cosmetics over the standard 2I IITs |
2IA IIT Features:
Photo Cathode type: Multi-Alkali
Resolution from 40 to 50 lp/mm
Signal-to-Noise Ratio from 14 to 20
5,000+ hour tube life |
CGTI IIT
The CGTI type of Image Intensifier are engineered for significantly enhanced performance over current 2nd generation IITs. The CGTI IIT is a Multi-Alkali compact 18mm format MCP Image Intensifier. Highlights of the CGTI specifications are the typical SNR of 15-22 and a resolution of 45-54 lp/mm. CGTI IITs are sensitive in a wide spectral band and thus provide good contrast in all scene circumstances |
CGTI IIT Features:
Photo Cathode type: Multi-Alkali
Resolution from 45 to 54 lp/mm
Signal-to-Noise Ratio from 15 to 22
10,000-hour tube life |
HPTI FOM 1250 IIT
HPTI tubes are an upgrade of the CGT Generation tube. They are a Multi-Alkali compact 18mm format MCP Image Intensifier. The HPTI tube increases sensitivity, resolution, Signal-to-Noise Ratio (SNR), and the Modulation Transfer Function (MTF). These improvements produce an exceptional image clarity and brightness.
Most HPTI specifications typically are equivalent or exceed standard 3rd generation. Highlights of the HPTI specifications are the typical SNR of 18-24 and resolution of 51-64 lp/mm. These tubes are designed to give optimal performance while being in compliance with the FOM 1250 requirement. State Department export license required |
HPTI IIT Features:
Photo Cathode type: Multi-Alkali
Resolution from 51 to 64 lp/mm
Signal-to-Noise Ratio from 18 to 24
10,000-hour tube life |
3rd Gen FOM 1250 (3I) IIT
Our 3I FOM 1250 Tubes (3I) are designed to support international sales of 3rd generation equipment to friendly countries. They have a micro channel plate, GaAs photocathode, and a completely self-contained integral high-voltage power supply. These 3rd Generation tubes provide a combined increase in resolution, signal to noise and photosensitivity over tubes with a multi-alkali photocathode. Generation 3 is the standard for the USA military.
These tubes are designed to give optimal performance while being in compliance with the FOM 1250 requirement. State Department export license required |
3I IIT Features:
Photo Cathode type: Gallium Arsenide
FOM: <1250
Resolution 51-64 lp/mm
Signal-to-Noise Ratio 18 to 24
10,000-hour tube life |
3 Gen FOM 1600 (3N) IIT
Our 3N FOM 1600 Tubes (3N) are designed to support international sales of 3rd generation equipment to NATO countries. They have a micro channel plate, GaAs photocathode, and a completely self-contained integral high-voltage power supply. These 3rd Generation tubes provide a combined increase in resolution, signal to noise and photosensitivity over tubes with a multi-alkali photocathode. Generation 3 is the standard for the USA military.
These tubes are designed to give optimal performance while being in compliance with the FOM 1600 requirement. State Department export license required. |
3N IIT Features:
Photo Cathode type: Gallium Arsenide
FOM: <1600
Resolution 64 lp/mm typical
Signal-to-Noise Ratio 22 Typical
10,000-hour tube life |
