You may find them more comfortable if there is slight convergence (this is also known as the eyepieces being “coned in”) because the experience is that the image we see is perceived by some people to be relatively close, at a distance at which their eyes would naturally converge.įor more detailed accounts of collimation see: Carl zeiss silvamar, which is a file listing the most likely dating carl zeiss jena 7x50. This is because the eyes are more sensitive to divergence than to convergence. so the optical paths from the binoculars are converging (see Chapter 2, footnote 3), and then to gradually collimate from there than it is to approach collimation from the other way. Note: It is usually better to set the binoculars so that there is a discernible amount of divergence, i.e. If there is not sufficient eccentricity in the rings, you will need to adjust the prisms. Repeat this until the images are aligned as well as possible. If it is not, slip the inner ring about 10º and repeat the rotation of the lens assembly. Rotate the objective lens assembly a small increment – say about 10 to 15º – at a time until it has made one revolution and see whether there is any movement of the image and, if so, if it is sufficient to bring the images into proper alignment. the narrowest part of the inner ring aligns with the widest part of the outer ring and vice-versa. ![]() Next, set the rings so that there is no eccentricity, i.e. It can be a tough test of perseverance and patience – you have been warned!įirst of all, mark the positions of the rings (see Fig 5-17) so that, if you do not manage to improve matters, you can at least set them to their original position. However, it is all but impossible to move an objective only either laterally or vertically, and collimation with eccentric rings can be monumentally frustrating until you get the hang of it. Moving the lens one way will move the image in the eyepiece the other way. Binoculars differ from telescopes in that collimation is achieved by lateral movement of the objectives, not by tilting them. From a certain book :-) (but note that the best you can get doing this is conditional alignment, not full collimation)Įccentric rings.
