See Light Like Never Before — The X-Cube Dichroic Crystal Prism

The X-Cube Dichroic Glass Prism is a mesmerising optical instrument that splits white light into its full RGB spectrum, creating a stunning rainbow effect right in the palm of your hand. Whether you're a science enthusiast, a curious student, or looking for a unique gift, this trichroic combiner/splitter cube is equal parts educational and magical.

What Makes It Special?

Trichroic Dichroic Design: Functions as both a light combiner and splitter, separating white light into vivid red, green, and blue channels — ideal for exploring the physics of optics and colour theory.
Premium Crystal Glass: Crafted from high-quality optical crystal with advanced precision cutting and a surface quality rating of 80/50 for crisp, clear refraction and virtually no distortion.
Compact & Durable: Measures 20mm on each side — small enough to carry anywhere, yet solid and resistant to clouding or fading over time.
Hands-On Learning: An excellent classroom or home physics demonstration tool that makes abstract light and optics concepts tangible and visual.
Perfect Gift Idea: Beautifully transparent and decorative — a thoughtful gift for students, teachers, photographers, and anyone fascinated by light and science.

Frequently Asked Questions

Q: What does an X-Cube dichroic prism do?

A: An X-Cube dichroic prism (also called a trichroic prism) uses thin optical coatings to split a beam of white light into its three primary colour components — red, green, and blue. Conversely, it can also recombine those three colours back into white light, making it a versatile combiner/splitter for optics experiments, photography, and physics education.

Q: Is this suitable for children and classroom use?

A: Yes! The X-Cube prism is an excellent hands-on educational tool for students learning about light, optics, and colour theory. It is compact, durable, and makes abstract physics concepts immediately visible. Adult supervision is recommended for younger children due to the glass crystal material.

Q: Will the crystal cloud or fade over time?

A: No. The crystal is made with quality optical glass and advanced cutting technology that ensures the prism remains clear and vivid with regular, gentle care. It is highly resistant to clouding and fading under normal use conditions.

Q: What size is the X-Cube prism?

A: The X-Cube measures 20mm on each side, making it a compact, portable size perfect for desktop display, classroom demonstrations, or carrying in a bag or pocket for on-the-go light experiments.
