The AN/PSQ-20A SENVG combines an image intensifier (I2) and an infrared (IR) micrometer into a compact monocular. The SENVG system, including the helmet mount and battery, weighs less than 2 pounds. SENVG will mount on the ACH helmet and will provide: upright, flip up, tilt, front/rear adjustment; use left/right eye; and quickly disconnect from the helmet.

The AN/PSQ-20A can operate on three AA lithium batteries with a consolidated operating life of more than 7.5 hours. 3-battery pack provides power for helmet or handheld use.

The AN/PSQ-20A Enhanced Night Vision Goggles (ENVG) provide enhanced capabilities by combining image intensity and long-wave infrared sensors into a single passive device mounted on the helmet. ENVG combines the low-light image detail provided by image enhancement with the ability to see through fog, dust and foliage of a thermal sensor. This thermal capability makes the ENVG, unlike previous night vision devices, useful during the day as well as at night. The two variants are AN/PSQ-20A and AN/PSQ-20B.

• Better situational awareness due to improved threat detection in most battlefield environments; Compatible with traditional weapon system range
• Operates on 3 batteries reducing life cycle costs
• Visibility is expanded from bright conditions to complete darkness (no light) and through obscure objects on the battlefield. Increased ability to operate in urban areas
• Improved wearing comfort due to better weight balance, resulting in less fatigue.
• Easy-to-use controls
• The eyepiece forms a non-exit pupil allowing the soldier to maintain a full field of view even when the helmet changes during vigorous physical movements
• Micro-color display
