    A discrete quality optical prism. It's ideal for reproduce Isaac Newton's prism experiment and show how sunlight is split into its separate colours. It's good science toys from Banggood.

    Awesome work, definitely! Came well packed and in a nice box. Absolutely transparent and homogenic glass, well cut and grinded. One of the corners has signs of additional polishing but does not make it bad, you got to be really picky to mention that.

    Das Prisma ist schön lang, so dass auch damit hantieren kann ohne es ganz zu verdecken. Mir ist mein Laser eingefallen und ich habe das Teil gleich mal damit beleuchtet. Beim Bestrahlend der angerauten Stirnfläche werden gleich alle optischen Unzulänglichkeiten sichtbar. Das waren zunächst meine Fingerabdrücke rundherum, die habe ich mit Microfasertuch beseitigt. Es bleiben ein paar Pünktchen, die von Einschlüssen im Glas herrühren. Ich tippe auf winzige Gasbläschen. Im normalen Sonnenlicht (da gibt es die bekannten Beugungs-Regenbögen) waren mir die Verunreinigungen nicht aufgefallen. Die sind wirklich sehr klein.
