Abstract
A lightweight holographic sighting system is provided that is designed to minimize optical aberrations common with earlier holographic sighting systems. The system has a modular construction that is more economic and conducive to high volume production, in terms of complexity of required fixturing and availability of materials, than earlier systems. The system is lighter and more compact, while providing a larger field of view than existing systems, and can be used on small hand guns, standard size firearms, bows, telescopes, and other devices without adding significant weight or space constraints. The system utilizes an upper housing assembly containing a high efficiency holographic optical element, an anti-reflective glass viewing window, and a red diode laser light source driven by a high efficiency microcontroller circuit designed for increased battery life, and a lower housing assembly containing two dielectric folding mirrors, an on-axis collimating lens, and a high efficiency achromatizing holographic optical element.
