Laser Ray Box ELECTRONIC w/o Power Supply One of our best products ever! 5 - beams Laser Ray Box - electronic (21-0311)- increases comfort of geometric optics education. It uses all the advantages of Laser Ray Box and extra - for shading the beams it doesn't need the mechanical shade. The electronic switching enables it. With the help of ON/mode/OFF key on the Laser Ray Box - electronic - you can switch the modes in this order: A. sleep mode, B. all 5 beams emited, C. beams 1,3,5 emited, D. beams 2,3,4, emited -, E. only beam 3 emited. After 60 minutes it automatically switches into sleep mode, Battery box is included. Art. num.: 21-0311 Unit price: 255.00€   012345678910

Laser Ray Box ELECTRONIC with Power Supply The Laser Ray Box Electronic (the same as 21-0311) supplied with Power Supply. Art. num.: 21-0312 Unit price: 269.00€   012345678910

Laser Ray Box w/o Power Supply The Laser Ray Box consists of five independent laser modules with a wavelength of 635 nm. Five clearly visible parallel line light traces can be seen when they are collimated by cylindrical lenses. It effectively demonstrates the transmission of rays through a combination of optical elements. The laser has magnetic back which enables it  to be easily used with Ray Optics Demo Sets (21-0401 or 21-0402). Battery box and mechanical shade is included.
