Assembly, it may have the structure design of monitoring light source, feature be to have lensed component body,
Filler is needed to remove the air between interface, to keep away completely between the second assembly and flat board filter disc three
Exempt from optical total-reflection.When needing to reduce light signal energy, as long as changing the flat board of specific standard
Filter disc, improves that aforementioned single type optical module is bad with two-piece type optical module plated film to be made
Become the problem of loss.But this design is when making, by internal for the colloid facing filling interface or
Outside residual bubble is difficult to the situation avoiding completely, once light signal runs into bubble, except reducing
The energy of light signal, is produced unnecessary spurious rays it is also possible to form communication in bubble interface
In noise, impact signal transmission.
