Physics Optical Experiment Set Multifunction Reflector Refraction Triangular Prism Convex Lens Concave Mirror Dial Linear Light Source Teaching Demonstration Equipment for Teacher Student Education

The lenses were good quality and worked just as described. The investigations/activities that were included were easy to follow and the price was great! The highschoolers were intrigued by the lenses and spent quite some time investigating the differences in each lens and their light path, even after our activities were complete!Plan to perform these activities in a darkened room, for best results. The pictures don’t sufficiently capture how well this worked.One of my students said she was creating art with the light path. Super cute!

This is a super educational optics toy, and comes with a decent variety of positive and negative lenses and a mirror tool to illustrate key concepts about reflection, refraction, and focus. You can even demonstrate total internal reflection with the prism, if you aim it just right. It doesn't have a right angle prism, which would have really made this set complete.It comes with decent enough instructions and explanations, but it doesn’t come with batteries (you need 2 AAA). Note that you can adjust the lasers to be perfectly parallel with a small screwdriver, if needed, and you can turn each laser on or off individually. These are a lot of fun to teach with, and really help illustrate ray tracing concepts well.The box has a pattern and scale on it that you can supposedly use. But my box was kind of beat up, and I thought it was easier to just demonstrate on a plain paper. The power level of the lasers is not noted, so I would be careful and treat it as a class III laser, and exercise appropriate safety practices, and teach your kids appropriate safety practices. I’m guessing it’s probably class II, but you just never know, and it’s not labeled. I am going to subtract one star for the lack of any laser label, or safety warning, because this really is important. It has a "small parts choking hazard" and "don't mix old and new batteries" warning, but nothing abouty laser safety.Final Rating: 4 stars! Lost a star for not having laser safety warning -- otherwise an excellent educational toy. It should probably also come with a right angle prism to better illustrate TIR.

My 10 yr old is learning about light and prism. This kit is helping a lot

This was a good kit. We used it for the optics unit for AP Physics

Poor build quality

The set does work as advertised; however, it is very cheaply made. Not sure it would survive many classes with students.

Cheaply made.

Physics Optical Experiment Set Multifunction Reflector Refraction Triangular Prism Convex LensMany STEM college degrees require a college physics or engineering physics, and this product is going to help out with some of the later chapters.This product is an excellent tool when you get to the chapter on optics. Sometimes it can be difficult to visualize reflection, refraction, and diffusion. It becomes especially difficult when you are giving angles and the index of refraction. This product takes your study to the next level by showing you exactly how light behaves when entering a medium at different angles.I love how the product provides 3 beams that drive home the point on this topic. Not only does it drive the point, but it gets you thinking creatively about convex and concave designs. Think of a magnifying lens.The beams are adjustable by a screwdriver, so you may offset them a little for your experiment, or you can make them as straight as possible.I have to knock this product a star because I was not too excited about the construction or the color used for the light box. The box uses a thin plastic that is not going to be very durable. You should take care not to damage the case. It is pretty flimsy. I also do not like that they used orange. Because of the flimsy material and the orange color, the laser can be seen through the box and it is bright. It actually hurts my eyes to look at it. You may want to consider wearing protective eyewear when handling this product.Overall, I am excited about this product because it provides some very valuable lessons in optics. I highly recommend this product as a teaching aid.
