1. The maximum object dimensions shown in the table are 90% of the theoretical maximum dimensions for a 9.2 mm x 9.2 mm (Kodak MegaPlus) format sensor;
providing a safety factor of magnification and alignment errors. For larger arrays, contact Navitar.
2. Lenses operated at smaller f/# may show reduced resolution, especially near the edge of the field of view.
3. Depth of field is calculated for a 30-µm allowable blur at the image (camera) plane at f/11 (for lenses with minimum operating f-number <f/16) or f/22 (for all others).
Note: Distortion is less than 2% for all lenses. Contact Navitar for distortion characteristics for a specific lens.
An accessory C-mount adaptor (59 LGT 101) is required for coupling F-mount Invaritar™ base lenses to a C-mount camera.
