It is placed in the second through-hole 411, lens 43 are set in the second through-hole 411, and face goes out light end 422.
That is, the second fixing seat 41 be set on pedestal 10 and the opposite position of the first fixing seat 21 on, also, its
On offer one for installing the second through-hole 411 of optically focused part 42 and lens 43.It is offered in the light inputting end 421 of optically focused part 42 more
A entering light slot being connected with multiple optical fiber 30, and optically focused part 42 go out light end 422 offer one and multiple entering light slots it is mutual
The light output groove of connection, light output groove and multiple entering light slots are interconnected, so that cavernous structure is formed, so that multiple optical fiber 30 were propagated
Light can form new light source, which can project with multiple and different waves after the convergence of the light inputting end 421 of optically focused part 42
The light of long range, and propagated outward after 43 optically focused of light end 422 out and lens, to be used as detection light source.
Advantageous, in some embodiments of the utility model, the outer end ecto-entad of the second through-hole 411 is formed with one
Two step surfaces and a third step surface, lens 43 are supported and are attached on second step face 4111, and optically focused part 42 goes out light end 422 and third
Step surface 4112 is flush.
That is, that second through-hole 411 is separated into three internal diameters is big for second step face 4111 and third step surface 4112
Small different part, wherein outer end that is to say that one end internal diameter far from optically focused part 42 is maximum, and interlude takes second place, inner end
It is one end internal diameter minimum for going out light end 422 for installing optically focused part 42, then, maximum one section of the internal diameter can mention for lens 43
