#1404-20  Compact Optical Bench. This unique optical bench is completely self contained and extremely compact!  The anodized aluminum channel opens up to form a long two meter bench, allowing testing of longer than usual focal length lenses.  This bench can also be used as two individual one meter optical benches.  The exclusive design of the lens holders allows instant changing of lenses and accessories without fussing with clips or screws and the holders slide smoothly along grooves molded within the case.  Everything except the light source folds up quickly into a package of slightly over 1/2 inch thick and can be set up in under one minute!  Comes complete with two aluminum benches, six different 38mm lenses, two optical screens, two object markers, four lens holders, one mini flashlight with clips and one mini candle which are your light sources.  Instructions are provided.
