The 31 Look, Re-engineered for Civilian Use
The 31-style night vision housing has become one of the most recognizable designs among night vision enthusiasts.
DTS-31L takes a different approach.
We developed an exclusive 18mm image intensifier configuration with a FOM range of 1200–1400, specifically for the civilian market.
Automatic Brightness Control & Bright-Light Protection

It supports:
- Flip-Up On/Off
- Side Flip-Up On/Off
- 50–80 mm eye distance adjustment
- ±5 diopter adjustment
