Laser line width, the full width at half maximum of the emission spectrum of the laser light source, that is, the half height of the peak (sometimes 1/e), which corresponds to the width between the two frequencies.
A device that converts the CO concentration variable in the air into a corresponding output signal.
Optical fiber temperature measurement technology is a new technology that has only been developed in recent years, and has gradually revealed some excellent characteristics. But just like other new technologies, optical fiber temperature measurement technology is not a panacea. It is not used to replace traditional methods, but to supplement and improve traditional temperature measurement methods. By giving full play to its strengths, new temperature measurement solutions and technical applications can be created.
Local Area Network (LAN for short) refers to a group of computers interconnected by multiple computers and other devices in a certain area. They are not far away from each other in physical locations to allow users to communicate with each other and share printers and storage. A system in which computing resources such as devices are interconnected together.
Let's take a look at which scenarios the DFB Butterfly Lasers is mainly used in.
A sensor is a detection device that can feel the information being measured, and can transform the sensed information into electrical signals or other required forms of information output according to a certain rule, so as to satisfy the transmission, processing, storage, and display of information , Recording and control requirements.
