This wiki currently differentiates the following housing types: Bi-ocular, Binocular, Monocular, Scope, Panoramic, Panoramic Binocular.

Monocular

A monocular housing consists of one objective lens, one image intensifier, and one eyepiece. It is worn in front of one eye.

Advantages

  • Least expensive
  • Lowest weight
  • One eye free[Note 1]

Housings

The following monocular housings have been documented on this wiki:

Bi-ocular

A bi-ocular housing consist of one objective lens, one image intensifier, a beam splitter, and two eyepieces. It is worn in front of both eyes, however providing no depth perception to the user.

Housings

The following bi-ocular housings have been documented on this wiki:

Binocular

A binocular housing consists of a bridge (sometimes with articulation) connected to two pods. Each pod consists of one objective lens, one image intensifier, and one eyepiece. It is worn in front of both eyes and provides the most natural viewing experience with full depth perception to the user.

Housings

The following binocular housings have been documented on this wiki:

Notes

  1. Using the unaided eye without having to take off the device is advantageous in some situations:
    • Environments with dynamic lighting, where the brighter areas can be observed without restriction
    • Focusing on nearby objects, given enough light, requires no focus adjustment (maps, text, electronic devices, signs, ...)
    • Aiming a weapon is less cumbersome
