Description

Prismatic adjustment device in the telescopic system

Affiliated technical field

The utility model relates to optical instrument field, specifically the erecting prism adjusting gear of telescopic system.

Technical background

Erecting prism in the telescopic system (being Abbe prism) is that the inverted image that is used for that telescopic system is become transfers erect image to, meets people's the custom of watching.But increased a prism, can if that is to say the incorrect words of prism placement location, will influence the optical axis of optical system the optical axis generation effect of system.So the adjustment of Abbe prism is the key of telescope assembling.Fig. 1 is exactly the wiring layout of prior art Abbe prism and prism table, and its adjustment purpose is: Abbe prism 1 is installed on the prism table 2, is adjusted into the optical axis (dotted line among Fig. 1) of Abbe prism and the locating surface of prism table orthogonal.

Present method of adjustment such as Fig. 2: use comparison goniometer (a kind of standard measuring instruments), the plane (is gone up with the optical axis and cushion block 3 reference fields 102 of the autocollimation light pipe 4 of comparison goniometer by elder generation, with Abbe prism seat surface of contact) adjust vertical, then Abbe prism group reference field is placed on fast 3 reference fields of pad, watch the autocollimation picture of Abbe prism reflecting surface 104 reflections with autocollimation light pipe 4, observe the autocollimation picture while adjusting 1, up to the autocollimation picture with till the reference position overlaps.This method of adjustment can be very high with the precision of reflecting surface and reference field adjustment, reach 5 seconds levels, but this method is based on design under each operating angle of Abbe prism 1 self and the strict free from error supposed situation of physical dimension, if self has prismatic error prism, so reflecting surface is adjusted to the verticality that requirement can not guarantee the reference field of the optical axis of whole Abbe prism 1 and prism table 2, still can be influenced optical system imaging.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, and the device of the prismatic adjustment in a kind of telescopic system is provided, and realizes the method for adjustment with the whole logical light of Abbe prism.

In order to realize above purpose, the technical solution adopted in the utility model is: the prismatic adjustment device in the telescopic system, it is characterized in that: comprise and adjust seat 5, the vertical laser instrument 9 of placing in adjusting seat 5, installation catoptron 8 (can adorn on the wall or the roof by mirror support above adjusting seat 5, as long as can allow catoptron by direction as shown), receiving target 7 places adjusts seat 5 outer sides.

Principle of work: the assembly that will adjust---Abbe prism 1 and prism table 2 place on the adjustment seat 5 of prismatic adjustment device, pass through prism 1 to catoptron 8 by the laser instrument emitted laser, reflex on the receiving target 7 by catoptron 8, whether rotate 2 prism tables observes laser spots position on receiving target 7 and changes and (promptly draw circle, in other words when rotating prism seat 2, the track that forms a circle or elliptical shape is moved in the laser spots position), if not change, then workpiece meets the requirements; If draw circle, then need to adjust Abbe prism 1.

Compared with prior art, the beneficial effects of the utility model are: 1, and it is the integral body adjustment to light path system, it adjusts precision is effective accuracy.2, reduce the unnecessary high request of Abbe prism.3, method of adjustment is directly perceived.4, help pipeline system and produce in batches.

Description of drawings

Fig. 1 is the wiring layout of prior art Abbe prism and prism table: wherein, and 1 Abbe prism, 2 prism tables, 101 locating surfaces.

Fig. 2 is a prior art comparison goniometer application drawing: wherein, and 1 Abbe prism, 2 prism tables, 3 cushion blocks, the autocollimation light pipe of 4 comparison goniometers, 102 reference fields, 103 reflectings surface.

Fig. 3 is the utility model structural representation: wherein, 5 adjust seat, and 6 adjust screw, 7 receiving targets, 8 catoptrons, 9 laser instruments, 10 elastic washers, 104 laser beam, 105 reference fields, 106 cylinder cylindricals.

Fig. 4: be the utility model application drawing: wherein, 1 Abbe prism, 2 prism tables, 5 adjust seat, and 6 adjust screw, 7 receiving targets, 8 catoptrons, 9 laser instruments, 104 laser beam.

Embodiment

Referring to Fig. 3: the prismatic adjustment device in the telescopic system, comprise and adjust seat 5, in adjusting seat 5, install laser instrument 9, adjusting seat 5 upper fixed catoptrons 8, receiving target 7 places adjusts seat 5 outer sides.

Described receiving target 7 usefulness a piece of papers or flat board just print or draw cross mark on the target.

Add an elastic washer 10 between laser instrument 9 and adjustment seat 5, it is fixing to adjust screws 6 with three.

Receiving target 7 places adjusts the place that seat one side is easy to watch, and is 6 meters to the cumulative distance of receiving target again from adjusting seat to reflective mirror.

Adjust seat 3 meters, 5 tops and settle catoptron 8.

Referring to Fig. 4: the application of prismatic adjustment device: when Fig. 3 state, open laser instrument 9, observe laser spots on the receiving target 7, mobile receiving target makes laser spots overlap with cross curve center on the receiving target.Abbe prism 1 and prism table 2 are placed on the reference field, and laser spots can not be offset (position of laser spots when not putting prism), otherwise will adjust Abbe prism.While rotating prism seat, laser spots can not be drawn circle on the observation receiving target.Meet above two requirements then adjust qualified.This method is by passing Abbe prism with beam of laser, and whether the check prism reflects skew to laser beam, and this is a kind of method that can adjust whole Abbe prism optical axis.

Prismatic adjustment apparatus regulating method: referring to Fig. 3

A) at first adjusting seat 5 requires reference field 105 vertical with 106 strictnesses of cylinder cylindrical adding man-hour.

B) then laser instrument 9 is connected with adjustment seat 5, adds an elastic washer 10 between them, it is fixing to adjust screws 6 with three.

C) this device is placed on the v block, seat is adjusted in rotation, regulates three and adjusts screw, and laser spots is incident upon on 10 meters targets far away, can not draw circle.Like this, show that laser beam and cylinder periphery adjust to coaxial, concentric.

D) catoptron 8 is settled in 3 meters high place above frock, places a receiving target 7 on the frock next door, and cross mark is arranged on the target, adjusts mirror angle and makes laser beam reflex to the laser target mark center.
