Description
Technical field
The present invention relates to concentrating device technical field, more particularly, to a kind of multiple light courcess concentrating device and with its
Sequenator optical system.
Background technique
In using multiple light courcess excitation fluorescence concentrating device, for the consistency for guaranteeing different laser excitation regions, usually need
To be calculated by stringent light path, the fine adjustment of μm rank, come guarantee different laser reach optical axis height at targets it is identical,
Spot center point is overlapped.It is existing to apply in the technology of sequenator, generally on the basis of a light source, directly project, in addition
Light source by reflecting mirror change optical path and reference light source and close beam and realize purpose.
It in the related art, include two light sources a: reference light source and one in multiple light courcess excitation fluorescence concentrating device
Non-referenced light source.The light that reference light source projects is emitted directly toward dichroscope, and transmits away, and the light that non-referenced light source projects passes through
Directive dichroscope after the reflection of reflecting mirror, and reflect away.Two light beams for transmiting and reflecting by dichroscope are closed one
It rises and forms the further directive system light path of light beam.When in concentrating device including more than two light sources, the number of reflecting mirror
It can accordingly increase, the light beam eventually formed is the synthesis of light emitted by multiple light sources.
This kind of structure can have the following problem:
1, to guarantee the collimation of reflecting mirror and dichroscope when two light sources, the light after capable of just making conjunction beam does not have differential seat angle
Different, this, which is adjusted, needs higher accuracy.And when light source increases to three, reflecting mirror becomes two, two reflecting mirrors with
Dichroscope should keeping parallelism.If light source is more, need the component of keeping parallelism degree also more, calculate tune-up amount it is big and
Complexity, system adjustment can be fairly cumbersome time-consuming.
2, with the increase of light source, the usage amount of eyeglass also increases, then optical path takes up space and can also greatly increase.
3, since light refractive index in glass is different, then after dichroscope light have the offset of micron dimension
(dichroscope thickness is generally 1mm).In order to ensure the consistency for closing beam, non-referenced light source need to be translated in micron dimension, especially
For multiple light courcess system, reference light source needs repeatedly to pass through dichroscope, if the wavelength and process of the light beam that reference light source issues
When the wavelength difference of the light beam of the non-referenced light source after reflection, then the offset at dichroscope is also different, optical path meeting
It becomes more complicated, not only needs accurate calculating, more again increase adjusting difficulty.
