Image Intensifier Tubes

Elbit GEN 3 18mm White Phosphor Image Intensifier Tubes

Elbit White Phosphor Image Intensifier Tubes (IIT) are 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.

Elbit MX-11769 (F9415) & MX-10160 (F9400) White Phosphor IIT

The F9415 and F9400 image intensifiers consists of a high efficiency GaAs photocathode bonded to a glass input window, a microchannel plate (MCP) current amplifier, and a white phosphor screen deposited on an inverting fiber optic output window. The Gen 3 photocathode is very sensitive to low radiation levels of visible and, especially, near infrared light. Tube lifespan is an average of 12,000 hours continuous use.

The F9415 IIT incorporates a variable gain power supply which gives the user the ability to adjust the tube gain or brightness in the field. This can be extremely helpful under high or low light conditions.

The F9415 and F9400 Tubes are available in several grades/FOMs based upon performance and blemishes (imperfections in the image). Currently we have FOM 2200+ and FOM 1400 to 1600 grades available. Only FOM 1600 or below IIT can be exported outside of the USA.  All F9415 and F9400 tubes come with a tube data sheet listing the following specifications: Signal to Noise Ratio (S/N), Resolution, EBI (electronic background input), HALO, Photocathode Response (PR). These specifications are the most critical to the actual tube performance, as no two tubes are exactly alike.
