Core II & Core III – image intensification tubes

Image intensification tubes for general observation, training, and demanding professional use.

The Core range offers seven performance levels. Core II models are based on Gen 2+ multi-alkali technology, while Core III models use Gen 3 gallium arsenide (GaAs) photocathodes.

The number in the model name indicates the guaranteed minimum FOM. Each tube supplied meets at least the stated value – it is not an average or typical performance.

Core II – Gen 2+ multi-alkali technology

Core II models feature a Na₂KSb(Cs) multi-alkali photocathode. Automatic gating (autogating) and external gain control are standard.

Core II 1200+
The entry-level model in the range for cost-effective device configurations, training, and backup systems. Suitable for general observation in low light. FOM at least 1,200 and SNR at least 20.

Core II 1400+
Higher FOM and SNR minimum values than the entry level for varying low-light conditions. FOM at least 1,400, SNR at least 22, and photocathode sensitivity at least 650 µA/lm.

Core II 1600+
An option for demanding observation and professional use. FOM at least 1,600, SNR at least 25, and photocathode sensitivity at least 800 µA/lm.

Core II 1800+
A high-performance option in the Gen 2+ range. FOM at least 1,800, SNR at least 28, and photocathode sensitivity at least 900 µA/lm.

Core II 2000+
The flagship model in the Core II range, with a minimum FOM equivalent to the Core III 2000+ model. FOM at least 2,000, SNR at least 28, and photocathode sensitivity at least 1,000 µA/lm.

Core III – Gen 3 GaAs technology

The Core III models' gallium arsenide photocathodes offer higher sensitivity than Core II models, based on the stated values.

Core III 2000+
For demanding professional use and low-light conditions. FOM at least 2,000, SNR at least 32, and photocathode sensitivity at least 1,900 µA/lm.

Core III 2200+
The highest FOM minimum value and photocathode sensitivity in the Core range. Suitable for demanding observation, such as on moonless nights and in dense forest cover. FOM at least 2,200, SNR at least 32, and photocathode sensitivity at least 2,000 µA/lm.

Technical Specifications Comparison

What do the performance values mean?

FOM (Figure of Merit) is the product of contrast and signal-to-noise ratio. It helps compare tube performance, but does not alone describe all the characteristics affecting image quality.

Signal-to-noise ratio (SNR) describes the ratio of the useful signal to noise. A higher value supports a cleaner image in low light.

Photocathode sensitivity (µA/lm) describes the electrical current produced by the photocathode per unit of incident light.
