A set of three <5mW Green LASER Blox™ has more versatility and flexibility than three green laser pointers could ever hope to! This versatile and economical combination allows you to magnetically stack the 3 LASER Blox™, so you and your students can construct a green laser ray box to easily study geometric ray optics. Shine 3 beams through various lenses and mediums to easily view and measure focal length and then separate them so each student can use a single LASER Blox™ for another activity.Three bright green LASER Blox™ allow for maximum visibility and versatility in teaching and learning about light, lasers and optics. Use each laser separately, either as a point source or with the line generator, or stack all three to create a fantasitically simple way to teach and learn about geometric optics with a ray box - mounted to the white board, you can easily conduct hands free laser demonstrations in front of the whole class!
Comes with a durable snap foam case, AAA Batteries and a line generating lens for each LASER Blox™.
