A Simple but Elegant Optical System No more electrical cords, and no more lamps to break!
Works great as a demonstration or student lab. The Introductory Optical System is designed as an improvement to mounted optical benches. Each acrylic component has a cut-out that allows it to securely rest on a familiar meter stick (not supplied). With this setup, students can easily make the common measurements of image and focal distance. The LED-illuminated object is self-contained, powered by 2 AAA batteries, and sufficiently bright to project an image on a unique semi-transparent screen (viewable from both sides); even with the lights on! Students will now have the freedom to perform all the requisite quantitative optical investigations.
