This unique optical bench is constructed of an anodized aluminum channel that opens up to form a long two meter bench, thus allowing testing of longer than usual focal length lenses. Or, you can use the bench as two individual one meter optical benches. Everything except the light source folds up quickly into a package of slightly more than 1/2″ thick and can be set up in under one minute. It includes two aluminum benches, six different 38 mm lenses, two optical screens, two object markers, four lens holders, one mini flashlight with clips, one mini candle, and instructions.
