In present embodiment, first adjustment part the 246, second adjustment part 248 and the 3rd adjustment part 249 are screw, and it wears three screws 254 of loading plate 252 respectively and is connected with installing plate 240.Therefore, three adjustment parts adjust point triangular shape distribution as three so that one plane of 3 definition, by rotating the adjustment part of correspondence, more obtain installing plate 240 and reflecting mirror 234 position also changes, and then the reflection light that have adjusted reflecting mirror 234 enters the position of second camera 212.
Further, ginseng Fig. 8, this eyeglass adjusts structure 236 and also includes elastomeric pad 262, this elastomeric pad 262 is between this installing plate 240 and this loading plate 252, therefore, the vibrations passing to reflecting mirror 234 in adjustment process are reduced as far as, and are conducive to the reflection light alignment at second camera 212 image space of reflecting mirror 234.The material of elastomeric pad 262 is selected from gum elastic or other elastomeric material.
This locating piece 244 is fixed on this plummer 202 and for positioning this support 238.Locating piece 244 offers positioning through hole 264 and is fixed by screws on plummer 202.Specifically, locating piece 244 is T-shaped, and it includes two lateral mass 266, and each lateral mass 266 offers positioning through hole 264, plummer 202 offers the screw communicated with this positioning through hole 264, and screw wears positioning through hole 264 and is spirally connected with corresponding screw and is fixed on plummer 202 by locating piece 244.
Second camera 212 is fixed on plummer 202 and offers the position of the second groove 216, and specifically, second camera 212 includes this second pedestal 268 of the second pedestal 268 and is fixed in this second groove 216.By arranging groove 216 so that second camera 212 is easier to mate with the reflection light of reflecting mirror 234 on horizontal level.
This second pedestal 268 is provided with the second guidance part 270, and this second guidance part 270 offers strip the second guide hole 272 that Y extends in a second direction.Second camera 212 receives the reflection light of reflecting mirror 234 and to these photoimagings, and then realizes the detection of the fluorescence information to sample chip.
This optical system 20 also includes photosurface adjustment part 274, and this photosurface adjustment part 274 is arranged on the reflected light path of this reflecting mirror 234 and for adjusting the position of the photosurface reflected light path of this reflecting mirror 234 relatively of this second camera 212.
Specifically, second camera 212 also includes adjustment block 276, this adjustment block 276 is positioned on this second pedestal 268 and fixes with photosurface and is connected, and this photosurface adjustment part 274 includes adjusting screw 278 and elastic component (not shown), and this elastic component is positioned between this adjustment block 276 and second pedestal 268.
When adjusting the screw 278 direction to close plummer 202 and screwing in, adjusting screw 278 can will drive adjustment block 276 and the photosensitive direction towards close plummer 202 to move, adjustment block 276 compression elastic piece simultaneously.When adjusting screw 278 and screwing out to the direction away from plummer 202, elastic component promotes adjustment block 276 and the photosensitive direction away from plummer 202 to move because of the effect of restoring force.Therefore, the relative position of the photosurface of screw 278 also adjustable second camera 212 and the reflection light of reflecting mirror 234 is adjusted.
Optical system 20 is when adjusting, first imaging lens 204 and dichroic mirror 206 are adjusted, the imaging of the reflection light of dichroic mirror 206 is mixed up by first camera 208, then with first camera 208 for reference, adjusts second camera 212 and make both align the image space of the transmission light of dichroic mirror 206.Specifically, dichroic mirror 206 can pass through to translate in the first direction on plummer 202, makes the reflection light of dichroic mirror 206 and then in first camera 208, afterwards, utilizes screw lock dichroic mirror 206 by dichroic mirror pedestal 220 and tighten dichroic mirror locating piece 222.
Afterwards, translatable mirror assembly 210 in the first direction, the reflection light making reflecting mirror 234 is roughly the same with the image space of first camera 208 at the image space of second camera 212, utilizes screw lock support 238 by support guidance part 256, and tightens locating piece 244.
Then, finely tune by adjusting first adjustment part the 246, second adjustment part 248 and/or the 3rd adjustment part 249 reflection light image space in second camera 212 to reflecting mirror 234, certainly, above-mentioned adjustment can be combined with photosurface adjustment part 274 and adjusts together so that adjust more flexible.
In above-mentioned optical system 20, adjust the some reflected light path to adjust illuminator 234 by three adjustment parts 246,248,249 as three, it is achieved that high-precision camera imaging position alignment, and improve the convenience of debugging and shorten the debugging time of system.
Further, in the fluorescence photo that each camera of optical system 20 of gene sequencer photographed, the image space of each camera is more accurate to obtaining the more accurate fluorescence photo analysis to the later stage, so the accurate alignment of the image space of each camera, it is possible to improve the accuracy of order-checking very well, reduce the loss of quantity of information.
The image space of each camera of optical system 20 of gene sequencer alignment request is high, so in the debugging process of optical system 20, the debugging in this stage need to spend the result that bigger manpower and time carries out debugging and being not readily available.After adopting above-mentioned eyeglass to adjust structure 236, it is possible to more convenient debugging more efficiently to desired effect, make producers can the debugging of completion system in shorter time, shorten the debugging time of system, improve the production efficiency of system.
It is to be noted, the optical system of the present invention is not limited to the image space alignment of two cameras, when optical system demand or when increasing more imaging band, as shown in Figure 9, this optical system increases dichroic mirror and the image camera of correspondence respectively, dichroic mirror or reflecting mirror before the camera increased use above eyeglass adjustment structure 236 to install equally, and then fine setting makes the image space of each camera be directed at reference position one by one, thus reaching the effect that all camera imaging positions are accurately directed at.It is understood that reference camera is also not necessarily first camera near imaging lens, it is possible to be some of last or centre, then finely tune the reflecting mirror before other camera or dichroic mirror angle is directed at.
