Description
Technical field
This utility model relates in cage and cage/discrete mixed electrical optical system the fine adjustment of light beam and is directed at, and belongs to photoelectric field.
Background technology
The adjustment of light beam be directed at the element task being to build electro-optical system, be also optical system application precondition.Along with developing rapidly of photoelectric technology, electro-optical system becomes increasingly complex, not only comprise substantial amounts of Light Electrical element, and complex electro-optical system often includes multilamellar or multi-platform multiple photonicss, even has relative motion between multilamellar or multi-platform photonics.Now how to regulate and collimated light beam realized the optical registration between multilamellar or multi-platform upper photonics, common optical axis between each photonics inner member, the multivariant skew of element self, thus ensureing that the detection of whole system and control accuracy are very important.Systematic optical axis is generally adjusted to suitable position by integrated electro-optical system before dispatching from the factory, it is necessary to time return factory-run school standard；Discrete electro-optical system generally adopts the double-pore structure of distance or short-range diplopore diffraction effect the center of element or system is adjusted and is directed at, the material in hole mostly is metal such as aluminum, rustless steel etc., not there is transparent characteristic, adjustment for light beam brings difficulty, for this problem, offshore company is had to be proposed transparent mode light pore structure.
The cage released in recent years and cage/discrete mixed electrical optical system adopt modular design, not only there is the advantages such as the compact conformation of integrated system, system area occupied be little, the user with separate structure can build system according to application demand autonomous Design, there is the advantages such as secondary development is easy, being subject to very big attention after release, the example product based on cage framework engenders.Part adopts cage construction, part to adopt traditional separated structure, thus the cage formed/discrete mixed structure is also the Research Emphasis of current photoelectric field.But cage and cage/discrete mixed structure have the feature such as compact conformation, limited space, make traditional distance diplopore or short-range diplopore diffraction regulate and be difficult to；Secondly as the frame for movement of cage photoelectric cell or module is different from other discrete element, traditional beam alignment and regulate framework cannot compatible or directly transplanting；And it is difficult to accurately judge the degree at BEAM SQUINT center when space is extremely limited.To building and in R&D process, the beam center of system regulates, photoelectric cell or the optical axis center alignment of intermodule, the multivariant skew adjustment of optical element itself etc. bring very big difficulty, the alignment accuracy making cage and cage/discrete mixed electrical optical system beam is relatively low, and this is also other pure discretes of ratio of precision of current cage system, a major reason that integrated form system is low.
Utility model content
This utility model is directed at coarse problem to solve light beam regulation difficulty, center in current cage and cage/discrete mixed electrical optical system, it is provided that a kind of cage and cage/discrete mixed electrical optical system fine adjustment alignment dish.
Cage described in the utility model and cage/discrete mixed electrical optical system fine adjustment alignment dish, including clouded glass and the aluminum ring after oxidizing blackening.Described clouded glass is provided with a through hole.In order to enable more closely to carry out the alignment of light beam and the analysis of optical quality, described clouded glass is carved with around this through hole donut groove.Described aluminum ring, its medial surface contains a step, and medial surface part except step is carved with screw thread.Clouded glass is embedded in ring by described aluminum ring, and the through hole on clouded glass is placed exactly in the center of aluminum ring, is used for being directed at visible light beam.
Described through hole, its center axis and aluminum Ring current distribution dead in line.
Described annulus groove, all centered by through hole.
The diameter of described clouded glass is more than the diameter of aluminum ring medial surface step place annulus.
The diameter of described clouded glass is identical with the diameter of aluminum ring medial surface screw thread place annulus.
Described step, is positioned at aluminum ring edge placement.Coordinated with the inside thread of externally threaded annulus with aluminum ring by one, together with step, clouded glass is fixed in aluminum ring.
This utility model and the difference of current existing procucts: on market, current existing alignment is taken inventory two shortcomings, first, it is impossible to compatible with cage electro-optical system, and clouded glass does not have annulus groove, light beam can not be carried out accurate adjustment and be directed at, and carry out the analysis of optical quality.Second, compatible with cage electro-optical system it be directed at dish and can not be precisely fixed in cage electro-optical system, bring certain error to the fine adjustment of light beam with being directed at.
Advantage of the present utility model: regulate for the accurate of light beam in cage and cage/discrete mixed electrical optical system and be directed at the instrument provided convenience, this fine adjustment alignment dish can pass through clouded glass and observe the position of lens sleeve pipe outgoing beam, annulus groove around small through hole makes the alignment of light beam be easier to make for, and increase the degree of accuracy of alignment, additionally, the analysis of optical quality also can be carried out on clouded glass.This fine adjustment alignment dish with adjust frame with the use of, can accurately alignment dish be fixed in cage electro-optical system, after light beam regulation is directed at, fine adjustment can being directed at dish and change other required optical elements into, this utility model achieves the service efficiency adjusting frame and maximizes.Additionally, this utility model also can be applicable in other non-cage optical systems.
