Slotted screen for use with Eisco's wall-powered Ray Box (RBX14). This screen measures 55 x 55 x 1.5 mm. It produces a variety of beams and rays, including one single wide beam, one single thin ray, three thin rays, or five thin rays. The wide beam is 19mm, and the thin rays are 1.5mm. This is a great tool for physics optics experimentation.
