In complex and dynamic application scenarios, ranging from a few kilometers to tens of kilometers, from broad-area search to detailed identification, a single observation device often proves inadequate. To address this, we offer a series of mature medium-wave infrared zoom lenses, represented by models such as 15-315mm, 21-460mm, 30-550mm, and 30-660mm. They are not merely optical components but systematic solutions tailored for different distances and scenarios, already widely applied in national defense, industry, and cutting-edge scientific research.

Solution One: Wide-Area Patrol & Mid-Range Precision Identification Solution (Covering 1-10 km Level)

Core Products: 15-315mm, 21-460mm, and other medium-wave infrared zoom lenses.

Problem Solved: Addresses the contradiction in traditional monitoring where "wide view compromises distance, and long-range view compromises width," enabling seamless surveillance of key areas and rapid response.

Distance & Scenarios:
Wide-Angle End (15mm/21mm): Provides a broad field of view up to several tens of degrees horizontally, suitable for panoramic surveillance of borders, coastlines, airport perimeters, and large facility compounds within a 3-5 km range, achieving gap-free patrol.
Zoom to Mid/Long Focal Length (e.g., 315mm/460mm): Can bring suspected targets (such as vehicles, vessels, personnel) from 5-10 km away into the center of the frame within seconds for feature identification and behavioral assessment to confirm potential threats.

Typical Solution Value: A single system integrating a 15-315mm or 21-460mm lens can replace multiple fixed-focal-length devices, significantly enhancing monitoring efficiency and situational awareness while reducing costs.

Solution Two: Ultra-Long-Range Precision Observation & Persistent Monitoring Solution (Covering 10-30+ km Level)

Core Products: 30-550mm, 30-660mm, and other medium-wave infrared zoom lenses.

Problem Solved: Breaks through the observation limits of the naked eye and conventional electro-optical equipment, enabling stable identification, continuous tracking, and detailed analysis of critical targets at extreme distances.

Distance & Scenarios:
Starting Focal Length (30mm): Provides a moderate field of view for capturing and locking onto large targets such as ships, wind turbine arrays, or high-voltage transmission corridors at 10-20 km.
Full Focal Range Extension (to 550mm/660mm): Enables detailed observation of targets at 20-30 km or even farther. Examples include identifying ship types, observing details of high-voltage tower insulators, or precisely locating distant mountain fire points.

Typical Solution Value: The 30-550mm and 30-660mm medium-wave infrared zoom lenses form the optical cornerstone for building long-range early warning systems, conducting advanced scientific observations (e.g., astronomy, atmospheric research), and ensuring ultra-long-distance security monitoring for critical infrastructure.

Solution Three: All-Weather Insight Solution for Complex Environments (Addressing Fog, Haze, Darkness)

All Series Products (15-315mm, 21-460mm, 30-550mm, 30-660mm) possess this capability.

Problem Solved: Overcomes the failure of visible light systems under low-visibility conditions such as night, haze, and dust, providing reliable 24/7 intelligence.

Scenarios & Capabilities:
Night Reconnaissance: Imaging relies entirely on the target's own thermal radiation, unaffected by complete darkness.
Penetrating Light Fog/Smoke/Dust: Medium-wave infrared wavelengths offer better penetration through atmospheric particulates, maintaining effective observation range in adverse weather—an advantage unmatched by visible light and short-wave infrared devices.
Detecting Camouflage: Directly detects hidden vehicles, equipment, or personnel through temperature differences.
