Reflective Surface Technology
Light has always been a human fascination. The discovery of new methods of harnessing and manipulating light helps us to better understand, control, and transform the world around us.
We at PCH asked ourselves how we could further this mastery, and create a technology that transforms light into poetry.
A brilliant canvas.
Mira is a surface treatment technology that empowers us to tell stories with light. It employs a set of algorithms to generate precise and controlled reflections, thereby transforming a plain surface into a shimmering canvas.
Hidden beauty is revealed upon the introduction of an external light source. The images produced are delicate and fleeting, flowing into view as easily as they ebb away.
Taking personalization to the micro-level.
Mira introduces an unprecedented degree of personalization to reflective surfaces – down to a precision of 0.5mm. This level of detail enables the creation of truly bespoke pieces, encoded with desired meaning.
We achieve up to 15x light amplification by redirecting light from multiple mirrors to the same light pixel. The size of a single light pixel corresponds to the size of an individual mirror, and can therefore be a minimum of 0.5 mm x 0.5 mm.
Minimum surface mirror size is 0.5 mm x 0.5 mm, although 0.75 mm is our standard. We use a custom made mirror drawing tool to ‘engrave’ patterns into the mirror surface, made visible through their varying reflective angles. There is no theoretical limit to the pixel size, and it is constrained only by the the size of available milling machines.
We can adapt the Z-contour of the mirror shape to any organic surface by ‘scanning’ it with our mirror cube grid. Concave shapes are not ideal, as they tend to block the reflected light and restrict access to the arm of the milling machine during manufacture. X and Y contours can be freely designed with the use of a custom made drawing tool.

The surfaces of our early pieces were optimized for parallel sunlight. Now, we focus on use with point light sources (e.g. smartphone flashlight). In the latest products, we aimed for best results with very close proximity light sources of just a few centimeters away (Buddha and ‘One Love’).
For optimal reflection quality, we use a special aluminum alloy containing a small percentage of copper (AlZn5, 5MgCu). However, we have also successfully milled copper, brass, steel, sterling silver, and pure aluminum.
“Any sufficiently advanced technology is indistinguishable from magic.” – Arthur C. Clarke
The technology behind Mira aims at blurring the boundaries between physical and digital, the material and the immaterial.
