LLI (Low Light Innovations) UH-1 Binocular

PLEASE INQUIRE FOR STOCK STATUS BEFORE PLACING YOUR ORDER

The Low Light Innovations UH-1 is a rugged articulating night vision binocular housing designed to deliver manual gain control, onboard IR illumination, and external power capability in a durable and field-proven platform.

Constructed from high-strength polymer with reinforced structural components, the UH-1 is built to withstand hard-use applications while maintaining a balanced weight profile for helmet-mounted use. The articulating pod design allows the user to operate with either one or both eyes while enabling a compact, low-profile stowed position against the helmet. Individual pods automatically power off when articulated, reducing light signature and conserving battery life.

The UH-1 features an intuitive control system with manual gain adjustment, onboard IR illumination with high and low modes, and simple “rotary-style” controls. This allows the user to quickly adapt to changing lighting conditions while maintaining consistent performance across varying environments.

The housing incorporates a friction-lock interpupillary distance (IPD) adjustment system along with user-adjustable pod tension, providing a secure and repeatable fit without tools. Power is supplied by a single CR123A battery, delivering extended runtime, while an integrated Fischer-style external power port allows connection to auxiliary battery packs for longer duration use.

The UH-1 is designed as a feature-rich, durable articulating system, offering a strong balance between performance, usability, and long-term reliability.

Image Intensifier Tube Options

Night Vision Outfitters offers several image intensifier options for this device, allowing customers to select the performance level and price point that best fit their needs.

All of our units are assembled using high-quality, meticulously-selected, brand-new tubes with strict cosmetic blemish and FOM tolerances to ensure excellent quality.

For L3Harris and Elbit tubes, key performance metrics will be provided via email for customer approval prior to shipment (FOM, EBI, HALO, Spots). Please note: L3Harris and Elbit tubes are manufactured in the USA, while NNVT tubes are manufactured in the PRC.

L3Harris Unfilmed White Phosphor

L3Harris unfilmed tubes represent the benchmark for Gen 3 night vision technology and excel in extremely dark environments with little or no ambient light. All L3 tubes we use are “UA” Aviation Grade, meaning they meet L3Harris’ most stringent cosmetic and performance tolerances.

L3Harris SuperGain Unfilmed White Phosphor

SuperGain tubes represent the most premium image intensifier technology currently available. While typical filmless tubes produce 40,000–80,000 fL/fc luminance gain, SuperGain tubes commonly reach 100,000–120,000 fL/fc, producing a brighter image and improved performance in the darkest conditions.

Elbit Systems USA Thin-Film White Phosphor

Elbit thin-film tubes deliver excellent Gen 3 performance at a slightly lower price point than L3 tubes. They perform particularly well in urban or mixed-light environments, making them a great option for users seeking a balance of performance and value.

North Night Vision Technology (NNVT) White Phosphor

NNVT tubes offer a more affordable entry point into night vision while still producing a strong image in moderate ambient light environments. NNVT tubes are a high-quality, high-FOM Gen 2+ technology and can be considered comparable to early Gen 3 performance levels. Please note: NNVT tubes are produced in the PRC, while L3Harris and Elbit tubes are produced in the USA.

Objective and Eyepiece Lens Options

Standard Mil-Spec Optics

High-quality Mil-Spec objective lenses and eyepiece optics are used as our standard optics and provide excellent image quality, clarity, and light transmission. These are typically manufactured by Noctis (Carson) or Night Vision Devices.

BrightPath Optics

These are high-quality optics that offer comparable performance to Noctis and Night Vision Devices but at a slightly lower price point than Mil-Spec optics.  They also provide a small weight reduction of approximately 0.5 ounces per optics set.

Rochester Precision Optics "RPO"

Rochester Precision Optics (RPO) ultralight objective lenses and eyepieces are available as an upgraded option. RPO optics are approximately 20% lighter than standard Mil-Spec optics while maintaining the same excellent optical performance.

Photonis Defense Boomslang Wide FOV

Photonis Defense Boomslang 50° wide-angle field-of-view (FOV) lenses increase the user’s viewable area by approximately 25% compared to standard Mil-Spec optics. Unlike earlier wide-FOV lenses, Boomslangs maintain no visible fisheye distortion with only minor chromatic aberration at the extreme edge of the image. Boomslang optics also reduce system weight by approximately 25–30 grams per eye compared to standard Mil-Spec optics.

ACT in Black Wide FOV

ACT in Black 50° wide-angle field-of-view (FOV) lenses increase the user’s viewable area by approximately 35% compared to standard Mil-Spec optics. These lenses maintain little to no fisheye distortion with only minor chromatic aberration at the edge of the image, while adding only approximately 20 grams per lens compared to standard Mil-Spec optics.

Warranty Information

The Low Light Innovations UH-1 is built to extremely rugged specifications and designed to withstand harsh professional use. These units carry a lifetime housing warranty along with a two-year warranty on the image intensifier tubes and overall system, so buy with confidence knowing you’ll be able to enjoy this unit for years to come.
