IR illuminator PULSAR Digex X850S 850nm range up to 100 m, model 79197

PULSAR Digex X850S is an IR illuminator operating at 850 nm with a specified effective range up to 100 m. Designed to supplement night-vision and thermal imaging devices, this compact unit provides additional near-infrared illumination to improve detection and identification of targets in low-light or no-light conditions. The model is mountable and intended for outdoor observation, surveillance, hunting and search tasks where extended infrared lighting is required.

Advantages

The PULSAR Digex X850S delivers concentrated 850 nm infrared output to increase contrast and recognition distances when used with compatible night-vision or imaging optics. Its compact design allows flexible mounting on tripods, rails or other supports while maintaining portability for field use. The device is tuned to provide a balance between beam range and power consumption, offering effective illumination up to the declared 100-meter range for common observation scenarios.

Suitable for

• Supplementing night-vision optics during low-light surveillance
• Outdoor observation and perimeter monitoring
• Hunting and tracking in conditions with limited visible light
• Search and rescue operations requiring extended near-infrared lighting

Key specifications

• Wavelength: 850 nm near-infrared
• Effective illumination range: up to 100 m (device-dependent and subject to environmental conditions)
• Form factor: compact, mountable housing suitable for tripod or rail attachment
• Primary use: supplemental IR illumination for night-vision and thermal devices
• Operating environment: designed for outdoor use in low-light conditions

How to use

Mount the IR illuminator securely on a compatible support such as a tripod, rail or dedicated bracket aligned with the optical axis of the night-vision or thermal device. Power the unit according to the manufacturer’s instructions and adjust aim so the beam overlaps the target area. Use the device in combination with your night-vision optic to evaluate beam coverage and intensity; reduce range or angle if backscatter occurs in fog, rain or dust. Routine checks of mounting and alignment will ensure consistent performance.

Recommendations

For best results, pair the PULSAR Digex X850S with night-vision or thermal imaging equipment rated for 850 nm sensitivity. Test illumination at shorter distances before extending to the maximum range, and avoid prolonged direct exposure of image sensors at close range. Consider environmental factors—such as fog, precipitation and vegetation—that can reduce effective range, and adjust mounting height and angle to optimise coverage while minimising unwanted reflections.
