Abstract
The utility model relates to a compensation device of a large-aperture Newton type optical system apparatus, which is an improvement of the compensation device of a large-aperture Newton type optical system apparatus, comprising a primary mirror, a main mandrel, a primary mirror counterweight, a secondary mirror reflector, a secondary mirror supporting seat, and a secondary mirror reflector counterweight. The secondary mirror reflector counterweight and the secondary mirror reflector are connected. The utility model solves the swing of the primary mirror of the system in the process of the following motion, using the secondary mirror reflector counterweight; a reverse swing is generated, so as to carry out the compensation of the swing of the primary mirror. After the compensation, the generated measurement error is small than 3.3'. The utility model provides an apparatus which can carry out the compensation of the large-aperture Newton type optical system, reduces the measurement error generated in the process of the measurement, and improves the measurement precision.
Description
The utility model belongs to optics, mechanical integrated technical field, relates to a kind of improvement to heavy caliber Newtonian optical system compensation system.
Prior art is as shown in Figure 1: it comprises that primary mirror 1, primary mirror axle 2, primary mirror counterweight 3, secondary mirror 4, secondary mirror catoptron 5, secondary mirror supporting seat 6 form.Be characterized in: primary mirror 1 comes support fixation by primary mirror axle 2, supports on the axle 2 being added with primary mirror counterweight 3 at primary mirror.
Heavy caliber Newtonian optical system in the past is when assembling, and in order to eliminate the measuring error of being brought of rocking of heavy caliber primary mirror, the mounting means that axle adds counterweight is worn at primary mirror employing center.Adopt aforesaid way can guarantee rocking between 0.02～0.1mm of primary mirror.
The purpose of this utility model is to solve the primary mirror of heavy caliber Newtonian optical system after assembling, because main system primary mirror in the pursuit movement process produces and rocks, make system in measuring process, produce measuring error, influence the problem of measuring accuracy, thereby a kind of device that can compensate heavy caliber Newtonian optical system is provided.
Detailed content of the present utility model: it comprises heavy caliber Newtonian primary mirror, primary mirror axle, primary mirror counterweight, secondary mirror, secondary mirror catoptron, secondary mirror supporting seat, secondary mirror catoptron counterweight, primary mirror is fixed on the primary mirror axle by its center pit, secondary mirror catoptron counterweight is connected with the secondary mirror catoptron, secondary mirror and secondary mirror catoptron are fixed on the secondary mirror supporting seat, and the weight of secondary mirror catoptron counterweight is determined according to the size that primary mirror rocks.
The course of work of the present utility model; Increased secondary mirror catoptron counter weight device at secondary mirror catoptron place, rocking of primary mirror generation compensated with this counterweight.Native system is installed on the transit, when system points to zenith, as the zero point of system, when the primary mirror of system when just putting or being inverted two horizontal levels, primary mirror changes and promptly rocks.This moment, the secondary mirror catoptron was because the effect of secondary mirror catoptron counterweight also and then produces rocks, and rock direction and primary mirror generation to rock direction opposite.
Good effect of the present utility model: rock because system's primary mirror in the pursuit movement process produces, opposite rocking of secondary mirror catoptron counterweight generation this moment compensates rocking of primary mirror, add counterweight on the secondary mirror catoptron, the influence of rocking measuring accuracy with the compensation principal reflection mirror has good effect.In engineering was used, when not adding secondary mirror catoptron counterweight, it was 5.5 "～27.3 " that primary mirror rocks the measuring error that is produced.After adding secondary mirror catoptron counterweight, rocking of primary mirror generation compensated, the measuring error that the compensation back produces is less than 3.3 ".The device that the utility model provides a kind of can reduce measuring error that measuring process produces, improve measuring accuracy, can compensate heavy caliber Newtonian optical system.
Fig. 1 is the structure principle chart of prior art.
Fig. 2 is the structural representation of a kind of embodiment of the utility model.
Embodiment of the present utility model is illustrated in figure 2 as: primary mirror 1, primary mirror axle 2, primary mirror counterweight 3, secondary mirror 4, secondary mirror catoptron 5, secondary mirror supporting seat 6, secondary mirror catoptron counterweight 7.Primary mirror 1 adopts K4 glass to make spherical mirror; Primary mirror axle 2 adopts the indium steel to make; Primary mirror counterweight 3 usefulness lead are made; Secondary mirror 4 adopts optical glass to make; Secondary mirror catoptron 5 adopts K9 glass to make; Secondary mirror supporting seat 6 usefulness steel pipes are made; Secondary mirror catoptron counterweight 7 usefulness leads are made.
