Nitehog Viper Lite

• 1x clip-on format: The thermal unit mounts in front of a daytime riflescope, so the rifle can stay set up as usual while adding thermal capability for night hunting or observation.
• 320x240 sensor with 15 mK NETD: This combination helps the device separate small temperature differences more clearly, which makes animals and other heat sources easier to distinguish in difficult weather and cluttered backgrounds.
• 60 Hz refresh rate: A fast frame rate keeps movement looking smooth, which matters when scanning, tracking, or shooting at moving targets with less blur and delay.
• Ultra-compact magnesium housing: At 254.00 g and 133.00 mm long, the Viper Lite adds less bulk to the rifle, helping preserve balance and making the setup easier to carry for long periods.
• 1380.00 m detection range: The thermal system is built to detect heat signatures at extended distance, giving the user more time to identify movement and plan the next step before closing in.

About the Nitehog Viper Series

The Nitehog Viper series is built as a thermal clip-on family that attaches in front of a daytime riflescope, allowing the primary optic to remain in place while adding thermal imaging capability. This concept suits users who want a dedicated hunting optics or tactical optics setup without replacing their familiar day scope or changing the rifle’s handling more than necessary. A key part of the series is the ability to attach or remove the clip-on without re-zeroing, which makes the system practical for rifles that alternate between daylight and low-light use.

Within the lineup, Nitehog has offered models such as the Viper 35, Viper 50 Next, and newer Viper 35 Gen 2 and Viper Lite variants. The range is aimed at both hunting and tactical use, with the Gen 2 family also appearing in Hunter and TAC configurations. Across the series, the design philosophy centers on compact mounting, repeatable alignment, and thermal performance that works with an existing riflescope rather than replacing it. That makes the Viper line especially relevant for shooters who value a modular rifle setup and want thermal capability in a form that remains close to the feel of a conventional optic.

About the Nitehog Viper Lite

The Nitehog Viper Lite is a 1.00 x thermal clip-on made for shooters who want the advantages of thermal imaging in the smallest possible package ahead of a daytime riflescope. Because it works at true clip-on magnification, it is intended to preserve the sight picture and shooting position of the day optic rather than replace it. In practice, that makes it well suited to night hunting and other low-visibility work where a familiar rifle setup helps speed and consistency.

Its thermal core uses a 320x240 microbolometer with a 12.00 μm pixel pitch, 15.00 mK NETD, and a 60.00 Hz refresh rate. Together, these characteristics support a clear, responsive thermal image with good separation between small heat differences and less motion lag when scanning or following moving game. The 35.00 mm objective with F 1.2 aperture contributes to the device’s ability to gather thermal information efficiently, while the stated 1380.00 m detection range gives it useful reach for spotting heat sources well before they are close.

The viewing side uses an OLED display with 1024×768 resolution, helping the image appear crisp and easy to interpret through the host riflescope. Nitehog also equips the model with Image Razor processing, designed to improve image usability in fog, rain, snow, smoke, and complete darkness. The housing is made from magnesium, which keeps weight down to 254.00 g while maintaining field durability. Waterproof, fogproof, and shockproof construction, plus operation from - 25 / + 50 °C, make the Viper Lite a practical thermal clip-on for demanding outdoor use.

About Nitehog

Nitehog Europe GmbH is headquartered in Berlin, Germany. The company is a family business focused on developing, manufacturing, and distributing multipurpose thermal imaging devices. Nitehog describes its background as spanning both optics and military imaging, which helps explain the emphasis its products place on compact design, repeatable mounting, and dependable operation in difficult field conditions.

Its lineup covers several thermal categories, including VIPER thermal clip-on devices, PYTHON thermal spotters, GECKO thermal monoculars, and the BOOMSLANG thermal sight. The company also offers SPOT HOG red-dot sights and SPOT HAWK prism scopes. One of the notable technologies associated with the brand is Nitehog Image Razor, an image-processing system intended to improve thermal image clarity in conditions such as fog, rain, snow, and smoke. That focus on thermal image usability is especially relevant in products like the Viper Lite, where practical field visibility matters as much as raw sensor specifications.
