The Duo Laser Ray Box - Electronic consists of five independent red laser modules producing five parallel lines that are collimated by cylindrical lenses to be highly visible. It is packed with the same features as the Laser Ray Box, but adds electronic shade control in the form of an on/mode/off switch, where the following light source modes are an option:
The Duo Laser Ray Box - Electronic is a complementary product for the Ray Optics Demonstration Set. It is taped with magnetic foil, allowing intuitive attachment to a magnetic board or use in conjunction with sheets and models from the Ray Optics Demonstration Set.
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) and a power supply (EU plug by default)..
