Lindsey 138mm +3 Diopter Brilliant Slot Close-Up Lens 30mm Slot

+3 diopters with a 30mm gap (air gap) between two 138mm +3 diopters "split" lenses cut to 39% of diameter.

Brilliant Rota-Slot close-up lenses are mounted in a geared turntable for quick and easy alignment. They are equipped with our Rota-Lock to lock the lens rotation at the desired angle.

Created for deep focus cinematography, slit diopters are used to create dramatic shots with near and far objects perfectly focused in a scene. Two lenses with cut edges are arranged with an air "slit" between them. The edges of the lens slit are usually aligned with the edges of the scene, like a door frame. Aligning the cut edges of the lens with the edges of the stage can obscure the trick. Because our slit diopters are mounted in a geared rotary filter plate, the slits can be quickly aligned with the appropriate stage elements and then locked in place with our Rota-Lock.
