Evaluate depth of field limits of fixed focus lens arrangements in thermal infrared

Electro-Optic Materials

The full text of this paper is available at the SPIE Digital Library.

The desire to implement lens arrangements without a focusing mechanism demands a deeper quantification of the Depth of Field problem. A new approach avoids the classic “accepted image blur circle”.

Very often, basic functions like recognition or detection of specified targets are tested for a certain lens. But what is the impact of changing the lens for one with a more detailed field of view? The necessary narrow field lenses tighten the Depth of Field problem. A calculation methodology will be presented to transfer depth of field results from an approved lens with a certain focal length and F/number to another lens.
