The Armasight Sirius is a high-tech, tough and durable multi-use monocular that delivers great Gen 2+ performance, but at the lowest possible cost. Packed with features, the Sirius is a unit that is equally at home with the hunter as it is with the professional security officer or law enforcement professional. Mission configurable, the Armasight Sirius can be hand-held, head/helmet mounted; it can be mounted onto a rifle with a variety of different mounts, or it can be mounted in front of a camcorder or camera for night photography. Optional 3, 5 or 8X lenses can turn it into a long range night viewing device in seconds.
Incredibly for such a low cost unit, the Sirius features manual brightness control, bright light shut-off circuitry and a spot/flood built-in IR illuminator. The Armasight Sirius is a night vision work-horse that will satisfy the requirements of the most demanding professional or casual night vision user with room to spare.

What do the different types of generation mean?
A Night Vision Device can be either a 1st, 2nd, 3rd or 4th generation unit. What this stands for is what type of image intensifier tube is used for that particular device; the image intensifier tube is the heart and soul of a night vision unit.
1st generation is currently the most popular type of night vision in the world. Utilizing the basic principles described earlier, a 1st generation unit will amplify the existing light several thousand times letting you clearly see in the dark. These units provide a bright and sharp image at a low cost, which is perfect, whether you are boating, observing wildlife, or providing security for your home. You may notice the following when you are looking through a 1st generation unit.
- A slight high-pitched whine when the unit is on.
- The image you see may be slightly blurry around the edges. This is known as Geometric Distortion.
- When you turn a 1st Gen. unit off it may glow green for some time.
- These are inherent characteristics of a 1st Gen. unit and are normal.
2nd generation is primarily used by law enforcement or for professional applications. This is because the cost of a 2nd Gen. unit is approximately $500.00 to $1000.00 more then a 1st Gen. The main difference between a 1st and a 2nd generation unit is the addition of a micro-channel plate, commonly referred to as a MCP. The MCP works as an electron amplifier and is placed directly behind the photocathode. The MCP consists of millions of short parallel glass tubes. When the electrons pass through these short tubes, thousands more electrons are released. This extra process allows 2nd generation units to amplify the light many more times then 1st generation giving you a brighter and sharper image.
2nd Generation Features:
- Photo Cathode type: Multi-Alkali
- Resolution from 40 to 45 lp/mm
- Signal-to-Noise Ratio from 12 to 20
- 5,000+ hour tube life
3rd generation image intensifier tubes are of the highest quality. They have a micro channel plate, GaAs photocathode, and a completely self-contained integral high-voltage power supply. These 3rd Generation tubes provide a combined increase in resolution, signal to noise and photosensitivity over tubes with a multi-alkali photocathode. Generation 3 is the standard for the USA military.
3rd Generation Features:
- Photo Cathode type: Gallium Arsenide
- Resolution 64 lp/mm
- Signal-to-Noise Ratio 22 Typical
- 10,000-hour tube life
4TH GENERATION represents the biggest technological breakthrough in image intensification of the past 10 years. By removing the ion barrier film and “Gating” the system Generation 4 demonstrates substantial increases in target detection range and resolution, particularly at extremely low light levels.
The use of film less technology and auto-gated power supply in 4th generation image intensifiers result in:
- Up to 100% improvement in photo response
- Superb performance in extremely low light level (better S/N and EBI)
- At least triple high light level resolution (a minimum of 36 lp/mm compared to 12 lp/mm)
