Originally designed as enlarging lenses, these high-resolution lenses can accommodate 1" format sensors and larger, which makes them a great choice for line scan cameras. This unmatched adaptability, combined with low distortion and constant resolution over the entire viewable field, makes Rodagon lenses optimal for close focus applications for which they consistently yield higher magnifications and better resolution than standard fixed focal length lenses. This makes them ideal for use with high-resolution cameras. Lenses have M39 x 1/26" base threading, except the 28mm focal length model, which has M32.5 x 0.5mm threads. Each lens comes with a separate base-mounting ring (replacement rings also available separately) to allow attachment to the Modular Focus Tube (MFT). The MFT is required for focusing the lens and for connection to standard camera mounts. The MFT ships with the C-mount adapter but camera adapters for F-mount, T-Mount (M42 x 0.75mm), SLR-mount (M42 x1.0mm), and M72 x 0.75mm are available (each sold separately). For closer working distances, additional extension tubes can be added (see "Working With Spacers" specification table); values should be used for reference only; choose #57-791 for M72 cameras and #56-965 for all others.
To use with a camera, attach either C-Mount adapter (included) to Focus Tube or use an F-Mount, T-Mount, SLR, or M72 adapter (each purchased separately). Extended range (25mm full stroke) accommodates range of working distances, without requiring spacers. Precision design allows lens to remain centered and unrotatable during focusing. Locking screw included.
