Exactly what you need!
Excellent quality. The glass is transparent, without any defects. A good red box for storage, it protects the product well.
Good quality prism in nice box.
Prisma de cristal bien pulido y acabado. Es una excelente oportunidad para enseñar conceptos básicos de óptica o para experimentar con la luz. Muy bien protegido, en caja de cartón rígido y acolchado en su interior, y a un precio ridículo.
Muy buena la calidad de este prisma, funciona correctamente, se presenta en una practica cajita. 100% recomendable
Very well packaged, and fast delivery. It should be noted that these are not a perfect equilateral triangle, and the length dose vary between the 3 I ordered. They do however break light into its component colours and show the rainbow effect. They come in a magnetically latched lined presentation box, a great gift for someone who likes experimenting with light and laser defraction.
The prism comes in a typical Chinese box, which protects it from breaking. The prism allows the breakup of sunlight in the wide spectrum of colors. Tip: orientate the beam of light horizontal to one of the three sides. This will cast rainbow colors at the ceiling. A distance of several meters from the prism to the surface is required for the colors to be visible. Disadvantage: it could be a little cheaper. Quality is good.
