Optics and Lasers in Medicine

One of the most prevalent applications of fiber optics in medicine are in the imaging and illumination components of endoscopes. Doctors use endoscopes to investigate symptoms such as nausea and abdominal pain, confirm diagnoses by performing biopsies, or give medical treatment. The flexible, yet rigid multi fibers enable visualization of internal organs and tissue via bodily orifices.

Examples of Medical Device Optics:

 ·   Disposable biomedical optics.

·    Endoscopes.

·    Fluorescence Imaging Systems.

·    Medical laser.

·    Ophthalmic lenses.

·    Automated refractors.

·     Portable ultrasound systems.

Lasers: 

Presently lasers are being widely used for numerous medical applications. These include surgery, ophthalmology, dermatology, angioplasty, cancer treatment, urology, cosmetic applications such as laser hair removal, tattoo removal and liposuction etc. When laser radiation falls on human tissues, different phenomenon may take place like reflection, transmission, scattering, re-emission and absorption

 Types of lasers used in Medicine:

 ·  Excimer laser

·   Yttrium aluminium garnet

·   Laser diode

·   Nd:YAG laser
