Main Page Products Company Contact Us Support Information
Overview
The HOLOgraphic Diffraction Sight (HDS) is the 1st electro-optic sighting system to apply holographic technology to small arms. When used in Close Quarter Battle (CQB) environments, this revolutionary optic delivers amazing speed and accuracy gains, un-compromised peripheral vision, and leaves no muzzle side operator signature. The HDS has been designed and tested to provide consistent, reliable performance even in the most hostile operational environments. The HDS is Waterproof (submersible), fogproof, shockproof, and withstands extreme temperature variations.
Durability
The HDS has been designed to withstand MIL-SPEC drop tests and still remain fully operational and hold zero
Waterproof
Designed to provide consistent, reliable performance. It is waterproof, fogproof, shockproof, and temperature proof.
Brightness Control
20 (twenty) brightness levels ensure proper brightness control in either low light or very bright sunlight.
Automatic Battery Check
An on-board microprocessor provides automatic battery check indicator, up/down brightness scrolling and programmable auto-shut down features.
No Revealing Signature
The HDS does not emit any muzzle side, position revealing light signature. The projected reticle pattern is visible only to the operator. Even Gen III night vision equipment cannot detect muzzle side signature.
Night Vision Compatibility
The HDS can be used in conjunction with Gen III Night Vision Systems. It can be operated with either head mounted or weapon mounted systems without causing “blooming” of the intensifier tubes. The HDS has 10 settings within the night vision mode.
Mounting Solutions
The HDS mounts to any 1” Weaver Dovetail Mounting Rail (supports Picatinny Interface) with a proprietary integral mounting platform adaptation to user preferred eye relief.
Batteries
The HDS operates on 2 (two) standard AA Alkaline Batteries.
