Abstract
The present invention relates to a laser guiding focusing device for a telescope, which is mainly composed of a left connecting jaw, a right connecting jaw, a cross bar, a vertical bar, a semiconductor laser, etc., wherein the semiconductor laser is placed on the front end of an eyepiece of the telescope, which can regulate the laser beam generated by the semiconductor laser, and the laser beam is reflected to a scale after jetting a remote plane mirror of through the telescope; then, a light spot is regulated for forming a small spot on the scale; thereby, the laser guidance and a focusing function of the telescope are realized. The present invention the operations that the plane mirror aligning, the scale (imagery) aligning, focal length regulation, etc. of an optical shaft of the telescope are in direct viewing under the condition of the guide of visible laser beam; the regulation is easy.
Description
Affiliated technical field
The present invention is used for optical lever micro-displacement measurement field.
Background technology
Measure in the Young's modulus of elasticity experiment of steel wire at pulling method, the invar silk is subjected to pulling force and the elongation that produces is very little, be difficult to measure with the general measure instrument, existing measuring method is to measure with the light lever method, but there are two problems here, the one, telescope optic axis aiming at a distance level crossing and in the level crossing leaf sight (as), the 2nd, telescopical focal length to be adjusted to this scale (as), because telescope optic axis is an abstract learning concept, the whether bad judgement of alignment surface mirror, even aimed at level crossing, focal length do not regulate put in place also can't see scale (as).This is for people who lacks experimental skill such as university student, and it is very difficult to regulate optical lever system, and the several hrs that has also be can not be completed this work.
Summary of the invention
Regulate the problem of difficulty in order to solve existing optical lever system, the invention provides a kind of laser guiding focusing device for telescope.Visible laser beam is passed telescope and is shone on the level crossing, and back reflection is to scale, and Here it is laser guide is focused again, and these processes are directly perceived because of moving, and also are very easy to finish even lack the people of experimental skill.
The present invention solves technical scheme that its technical matters adopts, and described laser guiding focusing device is installed outside telescope tube.Laser guiding focusing device for telescope mainly connects pawl, right connection pawl, cross bar, montant and semiconductor laser by a left side and forms.Described semiconductor laser (≤3mw) be placed on the telescope ocular front end, the laser beam that the adjusting laser instrument sends overlaps with telescope optic axis, and pass telescope directive level crossing at a distance along telescope optic axis, because of laser beam is visible, point to level crossing so can regulate laser beam easily, its reflected light also can point to the other scale of telescope easily, and this has just realized the laser guide function.Laser beam has been pointed to scale behind telescopical eyepiece, object lens, but the function of focusing that also is unrealized, as long as rotate the object lens adjustable screw, scale place spot size will change, explanation focusing end-of-job when laser facula on the scale becomes the point of a minimum.
At last laser instrument is rotated to other places, with human eye from telescope, observe scale (as), in general should be able to observe more clearly scale (as), if clearly inadequately remake suitable adjusting (generally only need finely tune) and get final product.
Advantage of the present invention is: under the guiding of visible laser beam, telescope optic axis alignment surface mirror, alignment scale (as) and focus and wait operation all to become very directly perceived, adjusting gets up to be easy to.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing and example:
Fig. 1 is a structural representation of the present invention.
Among the figure 1, the cross bar trip bolt, 2, cross bar, 3, the cross bar groove, 4, montant groove, 5, montant, 6, the montant trip bolt, 7, a left side connects pawl, and 8, the right pawl that connects, 9, packing ring, 10, pawl trip bolt, 11, telescope foresight, 12, telescopic sight, 13, telescope tube, 14, telescope ocular, 15, semiconductor laser.
Specific embodiments:
In Fig. 1, semiconductor laser (15), montant (5), cross bar (2), a left side connects pawl (7), right pawl (8) and the telescope tube critical piece mechanical connections such as (13) of connecting, the effect of montant groove (4) cross bar groove (3) is to be convenient to regulate up and down the position of semiconductor laser (15) and the direction of laser beam, the relative position of montant trip bolt (6) scalable cross bar (2) and montant (5), turning to and move left and right of cross bar trip bolt (1) scalable cross bar (2), pawl trip bolt (10) connects pawl (7) with a left side and is connected pawl (8) and is fixed on the telescope tube (13) with right.Semiconductor laser during use (15) places telescope ocular (14) front end, and laser beam is passed telescope directive level crossing back reflection to scale along telescope optic axis, regulates laser beam and become a fleck on scale, has just realized guiding and focusing work.Unclamp cross bar trip bolt (1) and turn to the top also can move semiconductor laser (15), do not influence operator's use and get final product to the telescope objective direction.
Claims (1)
1. laser guiding focusing device for telescope, it be by semiconductor laser, montant, cross bar and about connect pawl and the respective screws mechanical connection constitutes, it is characterized in that semiconductor laser places the telescope ocular front end, with the montant mechanical connection, montant can be shifted and be connected by the montant trip bolt relatively up and down with cross bar, cross bar can connect rotation or slip and fastening by the cross bar trip bolt in the pawl hole on a left side, about connect pawl and clamp telescope tube and fastening by the pawl trip bolt, laser beam is passed directive scale behind the telescope directive level crossing at a distance.
