 This is a portable laser power meter. The measured laser wavelength range is 11nm~19000nm, and its measured laser power range is 10mW to 50W . The measurement accuracy is 1mW.  The Power button is the ON/OFF switch. The zero button on the left is for reset to zero. Then turn on the laser, wait for the laser to enter a stable working state, and read the laser power data. After installing the power meter, adjust the detector position so that the laser is irradiated to the center of the detector. Our laser power meter has the characteristics of stable operation, accurate measurement, small size and long service life. Based on the calorimetric principle, it not only has the advantages of good optical uniformity, extremely insensitive to the influence of the laser polarization state and incident angle, etc., but also has a relatively high ability to resist laser damage.

 The fiber ASE broadband light source is an incoherent light source, which is the spontaneous radiation generated by the semiconductor laser pumping erbium-doped silica fiber, and the spectral flattening technology is introduced to achieve a broadband flat spectrum. The wavelength of the light source covers the C-band, and the spectral flatness is better than 2dB. It is output through single-mode fiber or polarization-maintaining fiber, which is suitable for applications such as fiber sensing. This is a ASE broadband light source with single-mode fiber. The fiber plugging and unplugging can easily damage the interface. The fiber here is fixed and cannot pluggable. The power can be adjusted by the button, and the adjustment accuracy is 1mW. This is the broadband light source of C-Band, and the broadband light source of L-band can also be customized. The laser of C-Band is infrared light, which is invisible to the human eye. Here is the use of ir photosensitive film to observe the ...

 The filter-type polarization-maintaining coupler uses interference-type filters to not only split the light beam from the input PM fiber into two output PM fibers, but also combine the light of two PM fibers into one PM fiber. This device can be used to separate high-power linearly polarized light into multiple channels without changing the linear polarization. It can also be used as a power splitter to monitor the signal of the PM fiber system without changing the polarization state of the optical signal. power. This is a 1550nm 1x2 PM fiber coupler. 1x2, 2x2 polarization maintaining fiber coupler is optional. 1310nm working wavelength is optional. The FC/APC interface is used by default, other interfaces can be customized. The Test Data Sheet of 1550nm 1:2 PM Fiber Coupler .
