KLLLBB - Klinger Laser's Laser Line Box Blue

KLLLBB - Klinger Laser's Laser Line Box Red Blue Laser Line Box provides a clearly visible red (635 nm) line light trace. It effectively demonstrates the transmission of ray through a combination of optical elements. Blue LLB (wavelength 450 nm). The Line is visible even under extreme conditions; therefore the laser is very effective in the demonstration of light trace. In principle, very similar device to the Red Laser Ray Box, but it emits one green laser beam because it contains one independent laser module. The beam is stretched by cylindrical lens to a clearly visible light source. The device is taped with magnetized foil, allowing intuitive attachment to a magnetic board or use in conjunction with sheets and models from the Ray Optics Demonstration Set. It also effectively demonstrates the transmission of rays through a combination of optical elements. By attaching multiple Line Boxes, a multi-beam source can be created. The set also includes a power supply, battery box (2x1,5V, AA size) and connecting cables for creating of multi-ray Line Box system. Specification: Laser type: YVO4 Wavelength: 450 nm Output Power/laser class: Pmax < 1 mW / 2 Dimensions: 80 x 25 x 24 mm Power Supply requirements: 3V DC / 500 mA
