This Ray Box is a simple, safe, and sturdy source of projected light for many classic optics experiments. Best of all, you don't need a completely dark room to conduct optic experiments due to its high-intensity light!

• Bright enough to use in ambient light
• Produces one, three, or five parallel rays
• May be powered with the included adaptor, or by an external laboratory source

Built in solid aluminum extrusion casing, it is supplied with a multi slit that produces either a single wide beam, or choice of one, three, or five pencil-thin rays. It produces parallel rays across a plane horizontal surface, and the rays are intense enough to be traced in natural light. It is supplied with a power adapter with all international safety certifications, which can be plugged into the mains source 100 to 240 V 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.
