Reading an NIR Photon Skincare Device Spec Sheet: The Numbers That Actually Matter
A spec sheet for an NIR device usually opens with a wavelength and a count of LEDs, and those two figures are the least informative numbers on the page. Peak wavelength describes the centre of an emission band, but emission spreads across a range, and the width of that range matters as much as the centre does.
Look for full width at half maximum, normally abbreviated to FWHM. A tightly binned 850 nanometre emitter may have a 30 nanometre FWHM, putting most of its output between 835 and 865. A loose bin can run twice that wide, pushing a substantial share of the output into wavelengths that penetrate less usefully and heat more superficially.
Irradiance is the second figure to verify, and it must be stated at a defined distance from the surface. Fifteen milliwatts per square centimetre measured against the lens is not the same as fifteen measured at the skin, because intensity falls quickly with distance. Suppliers who omit the measurement plane are usually quoting the flattering case.
Duty cycle and thermal limits are the honest constraints. LEDs driven continuously at high current shift wavelength as they warm, so a competent design either folds back drive current or pulses the array. A device quoting a maximum irradiance without a duty cycle is quoting an instantaneous peak the hardware cannot sustain.
Aolemon lists peak wavelength, FWHM, irradiance at a stated distance, duty cycle and the thermal foldback threshold on the datasheet for every NIR model, so a third-party test house can reproduce the figures before an order is placed.

Frequently asked questions
What does an EMS beauty device do?
EMS (Electrical Muscle Stimulation) sends low-frequency currents that contract facial muscles to improve tone and firmness, often paired with RF or LED for a multi-mode home spa device.
Are facial beauty devices CE and RoHS certified?
Export-ready units ship with CE and RoHS marks; RF/EMS models additionally need the relevant electrical-safety reports. Aolemon provides the test certificates for customs and marketplace compliance.
Do you offer OEM beauty-device manufacturing?
Yes — MOQ-friendly OEM/ODM with your logo, colour and gift-box customisation, plus engineering support for combined EMS+RF+LED platforms.
