Aplications of Lens:

Because of optical stability, good thermal stability, good coupling effective, gather and imaging features,the lensed fibers are widely used, they are available for the type of endoscopy, fax machines, photocopiers, fiber optic connectors, couplers, optical switch, wavelength division multiplexing, laser pump coupling lens, etc

Laser diode Due to diffraction, the beam diverges (expands) rapidly after leaving the chip, typically at 30 degrees vertically by 10 degrees laterally. A lens must be used in order to form a collimated beam like that produced by a laser pointer. If a circular beam is required, cylindrical lenses and other optics are used. For single spatial mode lasers, using symmetrical lenses, the collimated beam ends up being elliptical in shape, due to the difference in the vertical and lateral divergences. This is easily observable with a red laser pointer.

Raysung Photonics Inc:

Raysung photonics located in the export processing zone of Xi'an, China, is specialized in manufacturing FBG, lensed fiber and FBG filter for FTTH. Besides those three main products, Raysung can also manufacture wavelength stabilizer, DWDM FBG filter, chirped fiber grating, long period grating, custom fiber grating and so on. In addition, Raysung has ability to develop and produce special gratings for sensor. The company is committed to the research, design and producing of those products and it is the only one manufacture which has the capacity to volume- producing all sorts of fiber grating in China. Moreover, Raysung is one of the only manufactures in the world who has the capacity to manufacture the type of optical fiber which incorporates FBG and lensed fiber. Raysung's products are widely used in aerospace, construction industry, coal industry etc. The company's professional teams have rich experience in photoelectric area and we have advanced technology and equipment.
