A wonderful, easy to use kit with study activity book suitable for high school students. Teacher friend wanted to order class set but more were not available. Hopefully m,more will become available.

This is a very nice starter kit for introducing young students to geometric optics, qualitatively as well as quantitatively. Diaphragms in front of the lightbox allow selecting one, two, or three beams to be used in conjunction with lenses, prisms, and rectangular bars. On the back side, optical filters and mirrors can be used to study the additive mixing of colors, the reflection of colored light from differently colored slides, etc. The instruction manual is well done and provides guidance to a number of experiments. Altogether a very useful lab for the basics.

This is a nice set for the sub 70 price with a few caveats.Pros:Nice assortment of lenses, and they are opaque enough that the students can see the light rays traveling through the lens as well as entering and exiting.Light color mixing is acceptable, enough for students to see the general idea.Ray portion of box works well.Comes with a nice assortment of colored slides.Cost/teaching value is high. My students not only could see what was happening in the lenses but also experimented with different combinations of the lenses.Cons:Using the specified 2amp 12 volt power one of the colored filters warped after about an hour of use.The two curved mirrors are not high quality, it was more difficult for student to see the focal point on these than on an older set I have.The leads get in the way as they plug in the top.Note:It would be nice if this came with some worksheets, even in pdf form. I ended up tracing around the lenses to make sheets the students could use to report results and to investigate nearsighted/farsighted issues. I also made some worksheets with “blank” spots for lenses to go and the rays traced so they had to figure out which lenses to use to get the light to bend in that manner.I gave them a pretest after they had read about ray tracing and then again after the lab. The lab made a difference in comprehension.
