Applications
D.O. Industries, operating under the Navitar brand, produced zoom projection lenses primarily for use with slide projectors, overhead projectors, and other optical projection systems. The LNS1530 series with a 6"-9" zoom range was designed to allow flexible throw-distance adjustment without physically repositioning the projector — a common requirement in conference rooms, auditoriums, and educational settings from the 1970s through the 1990s. D.O. Industries and Navitar lenses from this era were widely used with carousel slide projectors and overhead transparency projectors. Today this type of vintage projection optic is sought by collectors, optical hobbyists, and technicians sourcing parts for legacy projection equipment. Due to the chip damage in this unit's elements, it is best suited as a parts source or for optical experimentation rather than active projection use.
This D.O. Industries Navitar LNS1530 3727 6"-9" zoom projection lens is being sold for parts or repair. The exterior barrel is in decent cosmetic shape with some light scuffing and wear consistent with age, and the zoom ring turns. However, there are visible chips in the lens elements — clearly shown in the close-up photos of both the front and rear interior elements. Because of this optical damage, the lens cannot be guaranteed functional for projection use and is being sold strictly as-is. Please view our photo set carefully and contact us if you have any questions.
