ApplicationsMedical & Health care

Light is needed everywhere to manage, maintain, improve, and monitor our health. Spectroscopic methods are often used to measure living organisms and samples (blood, urine, etc.), and precise measurements are realized through the complex combination of wavelengths across UV, visible, and IR.

• Medical visualization

  An endoscope that observes the inside of the body, such as the digestive system. The light that traditionally supports the observation of medical professionals is evolving into light that itself identifies even a small lesion. AI uses spectral image acquisition and fluorescence excitation in combination to identify lesions, and illumination is used in complex combinations of various wavelengths from UV to IR.

  • Optometry
  • Medical lighting

• Therapy

  When you hear about treatment using light, you may think of LASER scalpels or LASIK (keratotomy), but LED light is often used as well. For PDT (photodynamic therapy), in which a photosensitizer is administered, wavelengths such as 405 nm and 630 nm are used in accordance with the absorption characteristics of the substance, and that achieves the desired effect in treating tumors. Recently, cancer immunotherapy using the 690 nm band has become a hot topic. epitex LEDs contribute to the advancement of treatment in all wavelengths.

  • Acne treatment
  • Phototherapy
  • Cancer treatment
  • Hair growth

• Specimen inspection

  Optical measurements such as fluorescence measurement, absorbance measurement, and scatter measurement are often used for blood tests and urine tests, which are familiar in medical examinations.
  Light used for precise measurement requires precisely controlled wavelength, light distribution, and stability.

  • Cancer detection
  • Blood testing
  • Immunological test
  • Urinalysis
  • Fluorescent test

• Vital sensors

  Information on the amount of physical activity such as blood oxygen concentration (SpO2) and heart rate can now obtained easily and non-invasively with a wearable device, such as a wristwatch. These measurements use the wavelength characteristics of blood absorbance. This spectroscopic measurement has been further advanced and progress is being made at various development sites to non-invasively capture blood glucose and blood fat levels. In these measurements, IR with a long penetration depth into the body, especially the light of SWIR (1050 to 1750 nm), is optimally combined and used.
