IR diode lasers (typically 808 nm, 940 nm or 980 nm) are the gold standard in aesthetic dermatology, hair removal, surgery and physiotherapy. As the practitioner observes the treatment area at close quarters, 100 per cent protection of the retina against invisible radiation is essential, whilst ensuring that colour perception of the tissue is not distorted. Guaranteed certification and high visible light transmittance (VLT) ensure a comfortable clinical experience.
