The Panel
One instrument.
Six wavelengths.
Seventy emitters behind a steel body, holding a measured output for the length of every session.
Why it exists
Most panels are assembled to a price. Components are chosen because they are available, and the specification is written afterwards to describe whatever was built.
minara was written first. The wavelengths were selected against clinical evidence, the irradiance was fixed as a requirement rather than a result, and the housing was drawn around the thermal load the emitters would actually produce. Everything that follows on this page is a consequence of that order of operations.
Industrial design
Drawn to be left
in the open
At 318 by 220 millimetres and 70 deep, the panel is sized to be handled by one person and mounted without hardware you would need to hide.
There is no branding on the face, no indicator ring, no decorative venting. The only visible detail is the emitter array itself, because that is the part doing the work.
Engineering
Four decisions
that shaped everything else
01
Why seventy emitters
Fewer, brighter emitters produce a hot centre and a dim edge. Seventy lower-driven LEDs spread the same delivered energy across the whole treatment area, which keeps the dose even and lets each emitter run well below its thermal limit. Running cool is the single largest factor in how long an LED holds its rated output.
02
Why thirty-degree optics
A bare LED throws light in a wide, uncontrolled cone. Most of it never reaches the body, and what does arrives at an angle that reduces absorption. A 30° lens holds the beam where it is aimed, so the figure measured at the panel surface is close to the figure delivered at the skin.
03
Why steel, not moulded plastic
Plastic housings insulate. Heat accumulates behind the array, output drifts downward during a session, and the emitters age faster than their rating suggests. Cold-rolled SPCC steel conducts that heat into the body of the panel and away, which is why the output at minute twenty matches the output at minute one.
04
Why zero EMF
A panel used for twenty minutes a day sits close to the body for thousands of hours across its life. Driver placement and shielding were treated as a design constraint from the beginning rather than a figure to measure afterwards. The result is no detectable electromagnetic emission at the treatment distance.
Wavelength selection
Six, because
six could be justified
Every wavelength on this panel had to earn its place in the literature before it earned a position in the array. Depth of penetration rises across the range, so the six together cover skin through to joint rather than concentrating on a single tissue depth.
630nm
Visible red
Absorbed at the surface. The band most closely associated with skin tone, texture and collagen activity.
660nm
Deep red
Reaches beyond the epidermis while remaining in the range where cellular absorption peaks.
810nm
Near-infrared
The deepest practical penetration for soft tissue. Central to the recovery literature.
850nm
Near-infrared
Carries into joints and denser tissue where shorter wavelengths cannot reach.
940nm
Far-infrared
Extends the delivered spectrum and contributes gentle thermal effect at depth.
1060nm
Far-infrared
The upper boundary of the panel. Broadens coverage rather than concentrating it.
Materials
Cold-rolled steel,
chosen for what it does
SPCC is a structural steel, not a finish. It was specified for conductivity and rigidity, and the surface treatment came afterwards. A panel weighing 4.5 kilograms is heavier than it needs to be to hold seventy LEDs. That mass is the cooling system.
