WebAug 2, 2024 · Field Lens Design Considerations. 1.-. When designing a field lens for a microscope, be aware that most optical sensors (CCD, CMOS) are rectangular. Meaning that the camera FOV needs to fit inside the objective lens FOV. A way to do this is to make the diagonal of the camera sensor equal to the diameter of the FOV of the objective lens. WebA wider field of view will have a larger field size; a narrower field of view will have a smaller field size. Wide-angle lenses will expand a perspective, providing a larger field size. Telephoto lenses will compress a perspective, thereby magnifying the subject. For example, a 200mm lens will enlarge objects 2x more than a 100mm lens does and ...
