Interchangeable thermal camera lenses come in various types, including lenses with narrow fields of view (FOV). The field of view refers to the angle that the lens can capture. A narrow FOV lens has a smaller angle of view, resulting in a more focused and magnified image of a particular area or object. These lenses are suitable for applications that require capturing distant or smaller targets with greater detail and accuracy.
Here are a few common types of interchangeable thermal camera lenses, including those with narrow fields of view:
- Wide-angle lenses: These lenses have a broader field of view, capturing a larger area in a single image. They are useful for scanning large areas or monitoring spaces for general surveillance purposes.
- Medium-range lenses: These lenses offer a balanced field of view, suitable for moderate distances and providing a compromise between wide-angle and narrow lenses.
- Telephoto lenses (Narrow FOV): Telephoto lenses have a narrow field of view and are designed for capturing distant objects or specific areas with higher magnification. They’re ideal for applications requiring detailed imaging of smaller targets from a distance, such as in industrial inspections, perimeter security, or monitoring specific points within a larger area.
The choice of lens depends on the specific requirements of the thermal imaging application. Narrow FOV lenses, like telephoto lenses, are particularly beneficial for scenarios where precision and detail are crucial, but the target or area of interest is located at a distance. They allow for better magnification and clarity in capturing thermal data from distant or small-sized objects.
When using interchangeable lenses with thermal cameras, it’s essential to select the appropriate lens based on the desired field of view and the specific needs of the monitoring or inspection task at hand.
