Perfect for exploring the science of wavelengths, refraction, and diffraction.

• Three pen-style laser pointers: violet (approx. 445 nm), green (approx. 532 nm), and red (approx. 650 nm)
• Class 3B lasers, 8.5 mW
• Each laser is powered by 2 AAA batteries, included

This set is a handy tool for anyone interested in physics or optics. With three distinct wavelengths - violet, green, and red - you can explore the properties of different types of light. While laser pointers can be fun, it's crucial to use caution and avoid direct eye exposure.

The included batteries make this set ready to use right out of the box. Whether you're a student, teacher, or just curious about the science of light, this affordable laser pointer set is a great addition to your collection.
