[0002] When observing images through a binocular telescope, the human eye can fuse the images of the two eyepieces into one image. The relative image tilt is the angular difference between the left and right side barrel images. The national requirements for this project are relatively high. The national standard stipulates that the relative image tilt of the two side barrels of Class I is ≤30 minutes, and the relative image tilt of the two side barrels of Class II is ≤40 minutes; the debugging range of the eyepiece is generally 56~74mm for Class I and 58~70mm for Class II.
