By incorporating multiple chips, each being designed to emit a specific wavelength means a single device can emit light at multiple wavelengths simultaneously or sequentially.
By employing this technology, the multiwavelength VCSELs can be used for targeted treatment with minimal side effects. For example, in skin rejuvenation these VCSELs can target specific chromophores in the skin or tissue, allowing precise treatment without damaging surrounding healthy tissue.
Due to their small size they are easily integrated into handheld devises which make them compact, and ideal for various applications, including minimally invasive procedures.
This means there is also a cost saving as multiple wavelengths can be used in a single device. Other applications include hair removal, hair growth, scar rejuvenation, and ACNE treatment.
