1) After the light enters the beam splitter, the ordinary light can be divided into the following three types according to the wavelength:
Near UV: 200-380nm.
Vacuum UV (vacuumUV): 10-200nm.
Extreme ultraviolet, extreme ultraviolet (Extreme UV): 1-10nm.
2) From the perspective of human health and environmental protection, it can also be divided into UVA (315 ~ 400nm), UVB (280 ~ 315nm), UVC (below 280nm).
3) Another classification method is unimodal and multimodal.
Single mode: 1310nm. Multimode: 850nm.
There are three common interfaces for optical splitters, one is LC, the other is FC, and the third is SC.
