Armasight Sirius

The Armasight Sirius is an older device manufactured by Armasight by Flir.

When purchasing new, green phosphor or white phosphor (which Armasight calls "Quicksilver") can be chosen, but no spec sheet will be provided.

The device uses a 43mm non-inverting glass image intensifier tube, which has resulted in the device using an optical inverter in the eyepiece. This renders the device incredibly long, big and heavy - weighing in at 460 grams.

The optics used on the housing are of very poor quality, and as such the image has a blurry vignette around the edges, as well as very small eye-relief box, making it incredibly hard to look through.

The device is not ideal for head-mounting, but it does however contain two mini-rails on either side for accessories or mounting. The device also features a built-in IR illuminator, a power switch, and a low battery indicator. The device is MIL-STD-810F compliant.
