The Lumen Prismatica — an isosceles triangular optical prism made of high-clarity H-K9L optical glass. Dimensions: 25 × 25 × 80 mm. It diffracts white light into a cascade of crisp, vibrant rainbows. Used in photography, decoration, education, and visual art. A single ray of white light is enough for the effect.
Rainbow from the first ray
White light passing through the H-K9L prism breaks down into all its wavelengths — a crisp and vibrant colored dispersion, immediately visible with any natural or LED white light.
High-clarity H-K9L optical glass
High-quality polished optical glass (H-K9L grade), ensuring maximum light transmission and distortion-free dispersion — the professional quality of scientific instruments.
Photo & video accessory
Widely used in photography to create natural rainbow effects, artistic blurs, and refractions in portraits and still lifes.
Elegant design decoration
Its minimalist shape and crystalline transparency integrate into any interior — office, living room, shelf, collection setup or zen space.
25 × 25 × 80 mm — isosceles triangle
Compact and ergonomic format — easily held in hand, placed on a desk, or used in front of a camera lens.
Original & symbolic gift
For light, art, photography or physics enthusiasts — a magical effect that always surprises on the first demonstration.
Lumen Prismatica — H-K9L glass · 25×25×80mm · isosceles triangle · rainbow dispersion
White light appears uniform — it is not. It is the superposition of all colors of the visible spectrum, each with its own wavelength. The H-K9L prism separates them by deflecting each at a slightly different angle: red, orange, yellow, green, blue, violet — a crisp and vibrant chromatic cascade appears on any surface. This phenomenon of dispersion, described by Newton in 1666, is made everyday and accessible by the Lumen Prismatica.
Uses
Photography & video
Create natural rainbow effects, dispersion, or artistic blur in your portraits, product shots, and videos.
Physics education
Ideal demonstration tool to illustrate refraction, dispersion, and the light spectrum in physics classes.
Interior decoration
Placed near a sunny window, it projects changing rainbows onto walls and ceilings depending on the time of day.
Visual art & contemplation
Symbolic and meditative object for enthusiasts of light, optics, and scientific aesthetics.
| Material | High-clarity H-K9L optical glass |
| Dimensions | 25 × 25 × 80 mm |
| Shape | Isosceles triangular prism |
| Main function | White light dispersion — rainbow effect |
| Light required | Any white light — natural or LED |
| Uses | Decoration · photo · video · education · visual art |
| Box contents | 1 Lumen Prismatica optical prism (polished glass) |
For best effect: orient the prism at about 45° facing a direct white light source (sun, white LED, desk lamp). Project the dispersion onto a matte white surface to see the colors of the spectrum in their full saturation. In photography, place it in front of the lens halfway to the focal point for a partial dispersion effect.
🎁 A gift of light for curious minds: H-K9L glass, 25 × 25 × 80 mm, immediate rainbow dispersion. An original and elegant gift for a birthday, Christmas or photographer gift — for any light, art, design or physics enthusiast.
Frequently asked questions
Is this prism glass or plastic?
Made of high-quality H-K9L polished optical glass — not plastic or acrylic. Optical glass ensures maximum light transmission, distortion-free dispersion, and a high-end crystalline finish that plastic cannot replicate.
What type of light should I use to see the rainbow?
A single ray of white light is enough — natural light (sun, overcast sky), white LED lamp, or desk lamp. The more concentrated and directional the source, the crisper and more separated the colors of the spectrum will be.
Can it be used as an educational tool?
Absolutely — it is ideal for demonstrations in physics classes on light refraction and dispersion. It perfectly illustrates the decomposition of white light into the visible spectrum, the phenomenon described by Newton in 1666 and fundamental in optics.
How to use it in photography?
Hold the prism in front of your camera or smartphone lens halfway to the focal point. Orient it towards a white light source to create natural rainbows in the frame, or tilt it for artistic blur and partial refraction effects.
Is it a good gift?
Yes — the Lumen Prismatica is an original and elegant accessory that appeals to light, photography, art, and physics enthusiasts. Its visual effect always surprises on the first demonstration, and its minimalist design fits into any interior.

Our Pup Loves It
Size: 7" XL-Large
Our fur baby usually prefers toys that squeak, but she LOVES her pineapple 🍍 toy! It’s the perfect size, its hardness is strong enough for her to chew but soft enough to flex in her jaws , and doesn’t have a bad odor. For the money, it has been a great value with how it can handle her strong chewing and not break apart.

Great toy
Size: 7" XL-Large, Size: 7" XL-Large
My two dogs love to play with this. I bought the biggest size, I have 60lb boxer and 100lb malamute and it has been durable for them to play with. You can also stuff it with treats. If you bring it in the house make sure to rinse it off because it traps dirt in it.
