LWIR Dual Field-of-view (FOV) Lens

The LWIR Dual Field-of-view (FOV) Lens is designed for thermal imaging systems that need to switch between wide-area observation and detailed target viewing. Operating in the 8–12 µm long-wave infrared range, this lens configuration gives users two selectable fields of view within one optical system.

A wide field of view helps operators observe a larger scene and locate potential targets quickly. When more detail is required, the system can switch to the narrow field of view for improved target identification and inspection.

This combination makes dual FOV optics well suited to surveillance, perimeter security, industrial monitoring, and other thermal imaging applications where both coverage and detail are important.

LWIR Dual FOV Lens Overview

Wide and Narrow View Selection

A dual field-of-view design provides two optical viewing modes. The wide view supports general observation and scene awareness, while the narrow view provides a closer view of a selected area or target.

Instead of changing lenses manually, the imaging system can switch between the two views according to operational requirements.

Improved Situational Awareness

Using two selectable viewing angles allows thermal imaging systems to cover a broad area while maintaining the ability to examine specific targets in greater detail.

This is particularly useful for applications where an operator needs to detect an object first and then perform closer observation without changing the complete optical assembly.

Suitable for Dynamic Applications

Dual FOV thermal lenses are commonly considered for systems that require flexible observation at different distances. Typical applications may include: Perimeter and facility surveillance, Security and monitoring systems, Industrial thermal inspection, Long-distance target observation, Thermal imaging equipment or Custom infrared imaging systems.

Designed for LWIR Thermal Imaging

The LWIR Dual Field-of-view (FOV) Lens works with long-wave infrared thermal imaging systems operating around the 8–12 µm spectral range.

When selecting a suitable model, important parameters include detector resolution, pixel size, required field of view, focal length, working distance, environmental conditions, and system integration requirements.
