- 50mm F/1.8 objective lens
- 6.5-26x magnification
- 5.8° field of view
- 10.2m field of view at 100m
This dual-channel design gives users additional flexibility by combining thermal observation with high-resolution digital imaging.
Integrated 1,500-Meter Laser Rangefinder
The built-in 905 nm laser rangefinder allows users to measure distance without carrying a separate rangefinding device.
Rangefinder specifications include:
- Maximum measuring range: 1,500m
- Measurement accuracy: ±1m
- Wavelength: 905nm
