Triangular Prism,Crystal Optical Glass,Triple Triangular Prism Refractor for Physics Teaching Light Spectrum

I have one with me most of the time to make rainbows when the mood takes me, and surroundings allow of course, and have given several as gifts. Just one of those things that one should have for the beauty of it alone... but then there’s the scientific aspect as well, win-win object in my esteem 😁

Tiny, expected would be larger, check happy with the size before buying unlike me

Good for photography

Prism received seems like wrong type. This has a right angle cross section, not equilateral, and is more suitable for demonstrating total internal refraction. Disappointing.

This product arrived on time. It wasn't damaged and looks fine. I can't play with it yet as there's no sun, but will.

Arrived on time alot smaller than expected, (should maybe red measurements)

Good

Excelente comunicación con el vendedor.

It is not equilateral but right-angled. Wrong images!!! Doesn't fit my purpose. Returning.I am keeping a pencil in the picture for dimension reference for other customers.

Il prisma è semplicemente perfetto.Consegnato in una confezione ben protetta all'interno, è più piccolo di quello che si immagina, preciso che le dimensioni sono specificate, quindi tutto corrispondente alla descrizione.Acquistato per utilizzo didattico, i bambini di 5° elementare vedranno la magia della scomposizione della luce.Consigliato!

J'ai acheté ce prisme pour remplacer un autre que j'ai perdu. J'avais vu les dimensions, mais ça m'a quand même surpris en le recevant de voir à quel point il est tout petit. Par ailleurs, il semble avoir une coloration sur certaines faces que mon autre prisme n'avait pas, la lumière n'est pas renvoyée de la même manière
