This embodiment adopts first kind of mode that light is cut apart, in order to realize accurately cutting apart light, and guarantee the quality of monochromator bright dipping, prior art need be debugged monochromator usually, and this embodiment adopts after the technical scheme of summary of the invention part under the situation that does not need to debug, guarantee the light quality that of monochromator, improved the technique effect of detection efficiency when adopting following two kinds of technical schemes can realize at least guaranteeing out light quality on above basis again, first kind of technical scheme is:
Described light reflecting device comprises light-management members and the light partition member that will cut apart in proportion through the light that light-management members is handled;
Referring to Fig. 3, described light reflection box frame 47 comprises that the first box frame 49 reaches the second box frame 7 coplanar with the first box frame, 49 parts, described light-management members is positioned at the first box frame 49, the light partition member is positioned at the second box frame 7, see Fig. 7, the described second box frame 7 is provided with reception and disperses end through optical receiving end (this optical receiving end can be as the described light-receiving of this embodiment hole 47) and the dispersion of the light of light-management members processing through the light of the light of light partition member processing.See Fig. 4, the side of light partition member is provided with the light entrance port 9 relative with the described second box frame 7 light-receiving holes 47, and disperses the relative light of end to divide raw edge with the described second box frame, 7 light respectively.
It is a plurality of that described light disperses end to have, the dispersion direction that it arranges orientation and number after can handling according to the light partition member and be arranged on light in the light partition member and cut apart the type of mirror and decide, and the concrete form that described light disperses to hold also can be dispersion hole.
For example, for this embodiment, it can be that as shown in Figure 5 semi-permeable and semi-reflecting mirror 11 is (namely after this mirror is handled that described light is cut apart mirror, be divided into two kinds of light that disperse direction, half light reflection, half light transmission), at this moment, see Fig. 3, the light of the second box frame 7 disperses end to comprise light transmission end (being arranged on the second box frame 7 with respect to the light beam orifice 51 of the second box frame optical receiving end, one side) and light reflection end (being arranged on the second box frame 7 with respect to the light reflection hole 50 of Luminescent cases 2 one sides), see Fig. 4 equally, the side of light partition member is provided with respectively light-transmissive port 10 and the light reflex port 8 relative with the described second box frame, 7 smooth beam orifices 51 and light reflection hole 50.After light enters from light entrance port 9, will penetrate (referring to the dotted line of Fig. 5) from light-transmissive port 10 and light reflex port 8.
Second kind of technical scheme carried out further restriction to first kind of technical scheme, and namely the light partition member is a cavity; This dispersion direction that just means light can also be the cavity hatch direction except transmission direction and reflection direction.
