laser pointer is uninterrupted even there are many laser pointer users.
Fused is the two (or two above) to remove the coating fiber rely on a certain method of interference, heated to high temperatures, melting, while stretching to both sides, ultimately in the heating zone to form a double-cone form of the special waveguide structure, obtained through the control of fiber-optic torsion angle and the length of the stretch, the different spectroscopic ratio. Tapered curing adhesive curing on quartz substrates inserted into the stainless steel brass, this is the optical splitter. This production process due to the curing adhesive, thermal expansion coefficient and quartz substrates, stainless steel pipe is inconsistent, the degree of thermal expansion and contraction in the ambient temperature changes are inconsistent, such a situation easily lead to damage to the optical splitter, in particular, the optical splitter The situation is even worse on the field. laser pointer can be remotely controlled in a wireless way within 15 meters.
This is also the optical splitter is easy to damage the most important reason. The splitter can be produced more large ones with more than one splitter. Insertion loss of the optical splitter means each output me relative to input the number of dB of optical loss, and its mathematical expression is: Ai = the-10lg Pouti / Pin, where Ai is the i-th output port insertion loss; Pouti is the optical power of the i-th output port; Pin is the input optical power value. The additional loss is defined as the sum of the optical power of all output ports for the number of input optical power loss DB. It is worth mentioning that, for fiber-optic coupler, excess loss is to reflect the device manufacturing process quality indicators reflect the inherent loss of the device fabrication process, this loss as small as possible, making the quality of the merits of the assessment indicators. Insertion loss is only that the output power status of each output port. laser pointer has the energy-saving and battery leakage-proofing.The cladding is to provide a cylindrical interface, so that the light trapped in the core being, and reduce the scattering loss caused by the discontinuity of dielectric constant on the core surface. The overlayer wear an elastic plastic material, it enhances the strength of the fiber in the mechanical isolation or buffer external forces on the fiber-fiber ring. Therefore, only light in optical fibers, mainly the common role of the core and the cladding. There are two typical distribution of the cross section of the core and the cladding refractive index, a core and the cladding refractive index is uniformly distributed along the fiber radial, while the boundary surface in the core and the cladding refractive index into a ladder-like mutation, this fiber is called step-index optical fiber; another core refractive index of the radial coordinate with the core to increase gradually decreases, has been gradual change to equal the cladding refractive index.
