12X Lens Attachments

Lens attachments for the 12X Zoom system attach to the base of the system body tube and are available in a variety of magnifications. The nominall working distance of the zoom system is approximately 90mm. Lens attachments thread onto the bottom of the zoom system and can extend the working distance out to 350 mm or pull it in as close as 36 mm. The extending lenses (0.75X, 0.5X, and 0.25X) decrease the overall magnification, and increase the field of view. The shortening lenses (1.5X and 2.0X) increase the magnification and decrease the field of view. As the working distance goes from long to short, the "taking NA" of the system increases, resulting in an increase in resolving power.

Telecentric Attachments
There are three telecentric adapters available for use with the special 12X Zoom Lens, Straight (no coax), straight with coax, right angle folded. Each has a working distance of 188mm. Magnifications range from 0.16X to 1.94X with the upper 1X Adapter and 0.32X to 3.88X with the 2X Adapter. Maximum field of view is 50mm.

Right Angle (RA) Attachments
Navitar offers the object side right angle lens attachment for use with our 12X Zoom system. The attachment is added to the front of the 12XZoom and can be used with all lens attachments except for the 1-50015.
