This question is not specific enough. Do you want to know who invented the kaleidoscope? Do you want a list of companies that make them today? Do you want to know if aliens or super intelligent monkeys make them? I really don't know how to answer this.
Cheap kaleidoscopes made from plastic, cardboard, and other similar materials are made by all kinds of toy and novelty companies. However, high end kaleidoscopes, sometimes costing thousands of dollars, are generally made by artisans and not corporations. You can find these in specialty stores, artsy stores, and craft stores (not Arts and Crafts, a crafts store that sells high-end, hand made goods).
So, if you want a more specific answer you will have to ask a more specific question.
Kaleidoscopes has four syllables (ka-lei-do-scopes).

Periscopes and kaleidoscopes both use multiple mirrors to reflect and create unique visual effects or views. Periscopes are designed for viewing objects from a hidden or elevated position, while kaleidoscopes create intricate patterns by reflecting colorful objects inside.
Kaleidoscopes are used by people of all ages for enjoyment and artistic inspiration. They are popular among children for play and exploration of patterns and colors, as well as among adults for relaxation and creative stimulation. Artists and designers also use kaleidoscopes as a tool for generating ideas and patterns for their work.
