Optical Light Source(HK-20)


Optical Light Source(HK-20)

HK20 is a handheld optical light source, this optical light source can provide 1 to 4 wavelengths output to satisfy specific requirements including the 650nm visible light source and the 1310/1550nm wavelengths for single mode fiber or the 850/1300nm wavelengths for multimode fiber, as well as other wavelengths according to customer's needs. Together with the HK30 optical power meter, it is a perfect solution for fiber optic network applications.


Provides 1~4 wavelengths output which can be optional according to customers' needs

CW, 2Hz modulation output at 650nm, and CW, 270Hz, 1kHz, 2kHz modulation output at other wavelengths.
