Bausch & Lomb Optical Company Special Model D Balopticon for Large Plates For the benefit of those wishing to project plates larger than the standard size lantern slides we furnish the Model D Balopticon with 6-inch diametet condensing lenses in the regular triple system with patent, ventilated mount. It is particularly desirable for the projection of Lumiere autochrome plates, the binding of which generally leaves, even in the standard size plates, a larger opening than the ordinary lantern will cover fully. This outfit will project plates of any regular size up to 4 x 5 inches. It is supplied with two double slide carriers—one, our No. 4430, for standard size slides and the other for 4 x 5-inch plates. The latter is so constructed that one side will take the plate in a horizontal position and the other side in a vertical position. This will also be found a very attractive lantern for physicists who wish to have available an unusually large beam of light for projecting physical apparatus and the like. It can be very conveniently used for such work, since the bellows and different parts can be easi'y removed from the optical bed and other apparatus or materials adjusted as desired. To afford possibilities for a wide latitude of work this outfit is equipped with a 25-inch optical bed. 46
