DNT ThermNight 4K Night Vision & Thermal Multi Spectral Scope with Ballistic LRF
The DNT Optics TNC4K219R ThermNight combines thermal imaging, 4K digital day and night vision, a laser rangefinder and ballistic calculator in a single multispectral rifle scope. Thermal and digital imagery can be viewed independently or together, giving you more flexibility as lighting and conditions change.
Thermal & 4K Digital Imaging
The thermal channel uses a 256 × 192 uncooled infrared sensor with a 12 μm pixel pitch and NETD of less than 18 mK. Its 19mm objective provides a 9.2° × 6.9° field of view, making it well suited to scanning and detection.
The thermal channel has a 2x base magnification with digital zoom from 2x to 8x.
The digital channel uses a 3840 × 2160 4K CMOS sensor, providing considerably more detail for daytime and low-light identification. It has a 3x base magnification and digital zoom through to 24x, with 3x, 4.5x and 6x lossless zoom options.
A detachable IR illuminator is included for digital night vision use, with a stated range of up to approximately 400 metres.
Multispectral Viewing
The ThermNight's dual-spectrum display allows thermal and digital imagery to be viewed together. Thermal can be used for detection while the higher-resolution digital channel helps with identification.
Thermal Zoom Lock keeps the thermal image at its wider base magnification while allowing the digital channel to zoom independently. This means you can maintain a broad thermal view while using the digital image for closer inspection.
Thermal Auto Zeroing & One-Shot Zero
Thermal Auto Zeroing automatically calculates the thermal reticle position after the digital day/night channel has been zeroed, simplifying setup between the two imaging systems.
There is also a one-shot zeroing function designed to reduce the time and ammunition required during zeroing.
Integrated Laser Rangefinder & Ballistics
The built-in laser rangefinder measures from approximately 1.5 to 1,920 metres.
The DNT Ballistic Engine uses range information to provide real-time ballistic solutions. Multiple custom ballistic profiles can be created for different rifles, calibres and ammunition and synchronised through the DNT Optics App.
As with any ballistic calculator, the results depend on the accuracy of the information entered into the profile. It can do the maths, but it cannot correct incorrect ballistic data.
Reticles, Recording & App Connectivity
The ThermNight provides nine reticle styles and five reticle colours.
Built-in photo and video recording is supported, with 64GB of internal storage. Recoil-activated recording can automatically capture footage when a shot is detected.
Wi-Fi connectivity and the DNT Optics App provide live-view streaming, recording management, content sharing and ballistic profile synchronisation. One Tap Connect simplifies pairing with a compatible mobile device, while wireless firmware updates allow the scope software to be updated without manually loading files.
High-Definition Micro-OLED Display
The scope uses a 1920 × 1080 Micro-OLED display running at 60 FPS, with 65mm of eye relief for a comfortable viewing position.
The controls are designed for practical field use, including when wearing gloves.
Built for Outdoor Use
The TNC4K219R has an IP67 ingress protection rating and 800G shock resistance. DNT specifies the scope for high-recoil platforms including rifles rated up to .50 BMG.
The operating temperature range is approximately -20°C to 50°C.
At approximately 737g, the scope packs a lot of equipment into one unit, although its weight should be considered when building a complete rifle setup.
Battery & Power
The ThermNight uses a 21700 flat-top battery and provides approximately 5.5 hours of operating time under the stated conditions. It also supports external power through 5V USB-C.
Important: The battery is NOT included.
As with all DNT scopes, the battery is not included in the box. The TNC4K219R requires a 21700 flat-top battery, so make sure you add a compatible battery if you want to use the scope straight away.
