In the case of 45-degree polishing, the beam is emitted perpendicularly below the fiber, but the back-reflected light from the bottom of the fiber returns to the SMF and light source along the same optical path and at the same angle. In ...

The transmission efficiency is almost the same with or without reflective coating. We measured the reflectance of a SILICAGRIN "LEC" (Lateral Emitting Collimator) with and without a metallic (Au) reflective coating deposited on the tip, ...

Comparison in Single Mode Beam The diagram above illustrates the spread of the beam diameter of single-mode light emitted from the tip of an optical fiber and an optical fiber lens (wavelength = 1310 nm).The yellow-green light is the lig...

Selective treatment has become a global trend and theme in the medical world. Prioritize the patient's QOL and provide accurate treatment to the appropriate area. In the field of laser therapy using optical fibers, this is achieved throu...
