One standard.
Every tube.

Core is the image intensification platform in every Proton system. Every tube has to clear a guaranteed performance floor before it earns the name — that floor is the number you see in it.

Core II — Gen 2+ Core III — Gen 3 GaAs
Nomenclature FOM floor, guaranteed
Interface 3-pin, manual-gain ready
Warranty 2 years

Set apart on purpose.

Core III steps into Gen 3 GaAs territory — the sensitivity we reserve for conditions where seeing first isn't optional. Two tiers, held to the same guaranteed-floor naming as the rest of Core, and to nothing else.

Core III tube

[Why Gen 3]

GaAs Photocathode material — Gen 2+ runs a multialkali cathode instead
≥ 2000µA/Lm Peak sensitivity — roughly double Core II-2000's floor
≥ 32SNR Signal-to-noise ratio — the highest in the entire Core lineup
Core II tube

Five tiers. One family.

Core II is the main family of the Core platform: a Gen 2+ multialkali photocathode across five performance tiers, covering everything from a first deployment to serious low-light work. Each tier is named after its own guaranteed floor FOM — the number is a spec, not a marketing ceiling.

1200 Core II-1200 Entry tier — versatile use, training, and reserve units.
1400 Core II-1400 Strong performance-to-cost ratio for regular low-light use.
1600 Core II-1600 Mid tier — stronger sensitivity and resolution for mixed environments.
1800 Core II-1800 Demanding professional use — low noise, steady in heavy darkness.
2000 Core II-2000 The top of the Gen 2+ line — the sharpest Core II gets.

18 mm format, Ø36.75 × 30.4 mm, MX10160-compatible across the full lineup. Every tube ships 3-pin and manual-gain ready — upgrade any Proton Lite system to Omni Bridges and manual gain comes standard, no tube swap.

[Where Core lives]

One platform, every system.

Proton Lite Compatible with Core II and Core III with fixed gain. Proton Omni Same Core tubes, with manual gain unlocked through the Omni Bridge.

Every Core tube ships 3-pin, manual-gain ready — day one. Upgrade any Proton Lite system to Omni Bridges and manual gain comes standard. No tube swap. It was already built for it.
