EOTech 550 Series Holographic Sights

The Model 550 series of Holographic Sights, which includes the Model 553 Military Holographic Weapon Sights, Model 552 Holographic Sights, and Model 551 Holographic Weapon Sights, are fully compatible with all generation levels of night vision intensifier tubes.

A special night vision (NV) setting allows the operator to immediately drop the brightness intensity of the holographic reticle to eliminate any "halo" affect while viewing through an image intensifier tube. The Model 550 Series Holo Sights can be positioned in tandem behind night vision image intensifiers without any "bloom" of the target area. Now operators can combine the proven night vision technological advantage with a superior, close quarters weapon optic to achieve greatly enhanced weapon aiming – in complete darkness.

The Model 550 series' unique switches allow the operator to instantly drop the holographic sight reticle’s brightness to the NV mode of operation. The operator has the ability to toggle back and forth between the NV mode and the normal day/night operation within fractions of a second. The Model 550 Holo Weapon Sight has 10 distinct night vision settings to provide maximum flexibility to the operator. Typically, 3 to 4 brightness settings are not enough to support a host of constantly changing conditions including manufacturing variances in the sensitivities of the image intensifier tubes, varying ambient light environments, and varying light gathering sensitivities of the human eye across users. The Model 550 series still maintains the 20 normal brightness settings for normal day/night operations.
