LWIR Single FOV Lenses for Thermal Imaging Camera

Focal Length Range: From 4.8mm to 300mm, covering a broad spectrum of applications.

Compatibility: Fit for uncooled FPA detectors of various resolutions.

Design Variants:

  • Manual Focus Lenses: Allow manual adjustment of the focal length for precise focus control.
  • Motorized Lenses: Enable remote adjustment of the focal length for user convenience.
  • Fixed Focal Length Lenses: Provide a truly fixed focal length for applications requiring absolute stability.

Applications: Security and Surveillance, Industrial Inspection, Military and Defense, etc.

Field of View (FOV) for thermal cameras is defined as the maximum angle at which the device is sensitive to infrared electromagnetic radiation. The FOV is determined by the focal length of the thermal lens modules and the dimensions of the sensor/detector. Given a fixed detector dimension, the FOV is solely dependent on the focal length of the lenses. Single FOV lenses for LWIR thermal imaging cameras typically feature a fixed focal length, resulting in a fixed FOV.

Key Features and Adjustments:

In practice, although most single FOV thermal imaging lenses are designed with a fixed focal length, manufacturers often incorporate fine adjustment mechanisms to allow users to calibrate the focus. This ensures clear images whether the objects are near or distant, though the focal length remains nominally fixed. There are two primary mechanisms for adjusting focal length:

1.Manual Focusing Lenses:

  • Mechanism: Focal lengths are adjusted manually by hand.
  • Application: Suitable for scenarios where users can manually adjust the focus directly on the device.

2.Motorized Lenses:

  • Mechanism: Allows remote adjustment of the focal length without manual handling.
  • Application: Ideal for situations where remote focus adjustment is needed, enhancing convenience and safety.
