How It Works
The X-Cube uses a set of internal dichroic coated surfaces arranged in a cross pattern inside the glass cube. When light enters any face, these coatings selectively reflect and transmit specific wavelengths — separating white light into its RGB components or combining coloured beams into white light. It's the same optical principle used in professional camera systems and projectors, now in a beautifully compact display piece.

Frequently Asked Questions
Q: What is a dichroic X-Cube prism and how does it split light?
A: A dichroic X-Cube prism contains internal glass surfaces coated with thin dichroic films arranged in a cross (X) pattern. These coatings selectively reflect certain wavelengths of light while transmitting others, effectively splitting a single white light beam into red, green, and blue components — or combining separate colour beams into one. It's a real-world demonstration of wave optics and colour theory.
Q: Is this suitable as an educational tool for children?
A: Yes! The X-Cube is an excellent hands-on learning aid for students of all ages. It visually demonstrates light refraction, the visible spectrum, and RGB colour mixing in a way that's both engaging and easy to understand. Adult supervision is recommended for younger children due to the glass construction.
Q: What light source works best with this prism?
A: The cube works beautifully with any focused white light source — a torch/flashlight, a desk lamp, or even direct sunlight. LED flashlights with a tight beam produce the most vivid and defined colour separation, making the effect especially striking in a dimly lit room.
Q: Is the crystal prone to scratching or clouding over time?
A: The optical crystal used in this cube is designed to resist clouding and fading. While like all glass it can scratch if handled roughly, normal use and gentle handling will keep it looking brilliant for years. We recommend storing it in a soft pouch when not on display.
