DNT Optics Thermnight 4K Thermal (256x192) & Night Vision Multispectral Riflescope - 50mm w/LRF

DNT ThermNight 4K Thermal & Night Vision Multispectral Scope Imaging System

The ThermNight 4K uses Picture-in-Picture functionality to display the primary view alongside a secondary zoomed window, allowing thermal detection and detailed digital imagery to be viewed together. Digital and thermal channels can also be swapped between the main display and PIP window at the press of a button.

Thermal Detection

The uncooled thermal detector offers a 256 × 192 resolution, 12 × 12 μm pixel size and NETD rating of ≤18 mK. Its 19 mm f/1.0 objective lens provides a 9.2° × 6.9° thermal field of view, with a linear field of view of 16.2 × 12.1 yards at 100 yards.

Thermal magnification starts at 2× and extends digitally through 3×, 4×, 5×, 6×, 7× and 8×, supporting both close-to-mid-range scanning and more detailed observation.

4K Digital Day & Night Imaging

A 3840 × 2160 CMOS sensor provides high-resolution digital day and night imagery through a 50 mm f/1.8 objective lens. The digital channel has 3× base magnification, with digital magnification options of 3×, 4.5×, 6×, 9×, 12×, 18× and 24×.

The detachable IR illuminator is designed to assist visibility in low-light conditions and is stated to provide visibility at up to 450 yards.

Rangefinding & Ballistic Support

The integrated laser rangefinder provides a ranging distance of 5–2000 metres / 5–2100 yards. The DNT Ballistic Engine is built into the system to support calculated shooting solutions using the measured range.

DNT ThermNight 4K Thermal & Night Vision Multispectral Scope Review

The DNT ThermNight 4K is a multispectral riflescope designed to combine rapid thermal detection with detailed digital day and night identification. Its dual-sensor arrangement, integrated rangefinder and ballistic functionality make it particularly suited to users who want thermal and digital capability within a single optic.

The combination of a wide thermal view, high-resolution 4K digital channel and Picture-in-Picture display is the defining feature, allowing both detection and identification information to remain readily accessible.

DNT ThermNight 4K Performance & Key Features

The thermal channel uses a 256 × 192 sensor with ≤18 mK sensitivity, while the digital system uses a 3840 × 2160 CMOS sensor. The two imaging systems complement one another: thermal imaging provides rapid target detection, while the 4K digital channel is intended to provide greater visual detail for identification.

• 2× base thermal magnification with up to 8× digital magnification
• 3× digital base magnification with up to 24× digital magnification
• Integrated laser rangefinder with up to 2100-yard range
• Picture-in-Picture multispectral viewing
• Detachable IR illuminator for low-light digital use

Build Quality & Handling

At 737 g and 196 mm long, the ThermNight 4K integrates thermal, digital, ranging and recording technology into a single housing. An IP67 ingress protection rating and recoil rating of 800Gs / .50 BMG provide clear indicators of its suitability for demanding field use.
