One clearly visible green (532 nm) line light trace can be seen when it is collimated by cylindrical lenses. It effectively demonstrates the transmission of ray through a combination of optical elements.
Green LLB is the updated version of Laser Line Box emitting the ray of a green color (wavelength 532 nm). The human eye is 3 times more sensitive to green light than red light. 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 Green Laser Ray Box, but emits one green laser beam, because it contains one independent laser module. The beam is stretched cylindrical lens - clearly visible bar light source. It is taped with magnetized foil, allowing intuitive attachment to a magnetic board or use in conjunction with sheets and models from Ray Optics Demonstration Set. It also effectively demonstrates the transmission of ray through a combination of optical elements. Via attaching multiple Line Boxes, multi-beam source can be created. Set includes also battery box (2x1,5V, AA size), power supply and connecting cable for multiple Line Boxes.
