• Apparatus Contains: (1) Sheet metal outer case, (1) Halogen Bulb, (1) Fixed Lens, (1) Wall plug, (1) Skit card with multiple options
• Ray box produces parallel convergent rays across a horizontal plane
• Perfect for use with acrylic or glass demonstration optics to teach geometrical optics
• Ray box has various configurations to create different ray patterns
• Works off of standard 100-240V wall power, no power supply required (although one can be used for more power)

This new EISCO Ray Box is a simple, safe and sturdy source of projected light for many classic optics experiments-best of all, you dont need a completely dark room to conduct optic experiments due to high intensity light used. It produces parallel convergent rays across a plane horizontal surface and the rays are intense enough to be traced in natural light. Built in solid aluminum extrusion casing. Is supplied with a multi slit that produces either a single wide beam or choice of one , three or five pencil thin rays. It is supplies with a power adapter with all international safety certifications which can be plugged into the mains source 100-240V 50/60 Hz, or an external power supply may be used in the lab. It comes with a fixed lens, a slit with multiple sides and an adaptor.
