NULL Lens – Target Optical Collimator Kit

This NULL lens is in fair condition. It has been rented out over the decades and has got a few minor scratches, but nothing major at all. Still works perfectly.

This NULL Lens is a perfect tool when you are outside and your subject is far. Anything over 150′ (50 meters) and you can set focus accurately to 5 microns. In some situations, however, such as setting up in a car at night, this can be difficult. That’s where the NULL Target can come in handy. It contains a backlit Siemen’s Star, a focusing target that makes it easy to judge focus accurately. Optics in the NULL Target bring the Siemen’s Star into clear focus at infinity. The NULL Target screws into the NULL Lens, and then that device is used to set back focus as usual – only now you don’t have to worry about pointing the camera, because everything is built into the NULL assembly.

The whole unit is small, lightweight, internally powered, reliably accurate and easy to use.
