LRB-3ELEC-KL Klinger Laser's 3 Beam Electric Ray Box

Klinger Laser's 3 Beam Electric Ray Box Economic version of Laser Ray Box Electronic, but with 3 red rays 3-Beam Laser Ray Box Electronic represents an economic version of Laser Ray Box Electronic but contains only 3 red laser beams. It also includes the mode switch which increases the comfort of geometric optics education. The 3-Beam Laser Ray Box Electronic consists of 3 independent red laser modules producing 3 parallel lines that are collimated by cylindrical lenses to be highly visible. The on/mode/off switch provides the following light source modes in the option: three rays (1,2,3) two rays (1,3) single ray (2) The 3-Beam Laser Ray Box Electronic is a complementary product for the Ray Optics Sudents Set therefore it is not taped with magnetic foil on the bottom. The laser is very effective in the demonstration of light traces. It also effectively demonstrates the transmission of rays through a combination of optical elements. Five clearly visible parallel line rays can be seen easily due to collimation by cylindrical lenses. The set also includes a battery box (2x1,5V, AA size) but does not include a power supply. Specification: Laser type: Diode Wavelength: 635nm Output power/laser class: Pmax < 1mW / II. Ray distance: 18 mm Dimensions: 112 x 63 x 32 mm Power supply requirements: 3V DC / 500 mA
