How To Align Binoculars At Home

“Collimating” Binoculars - How To

The following is a list of articles, books and websites which in my opinion contains excellent resources for the study of binoculars especially vintage ones and has been of invaluable assistance to me in learning about binoculars and writing the descriptions of the binoculars in my collection. It is by no means comprehensive and, hopefully, will be updated frequently. Note: If you have a vintage binocular you either wish to sell or would just like some information about, I can be contacted at flagorio shaw. Bulletin of the Scientific Instrument Society, , No. Reid, William "Binoculars in the Air".


Binoculars or field glasses are two telescopes mounted side-by-side and aligned to point in the same direction, allowing the viewer to use both eyes binocular vision when viewing distant objects. Most are sized to be held using both hands, although sizes vary widely from opera glasses to large pedestal mounted military models. Unlike a monocular telescope, binoculars give users a three-dimensional 3D image: for nearer objects the two views, presented to each of the viewer's eyes from slightly different viewpoints, produce a merged view with an impression of depth. Almost from the invention of the telescope in the 17th century the advantages of mounting two of them side by side for binocular vision seems to have been explored. The Galilean design has the advantage of presenting an erect image but has a narrow field of view and is not capable of very high magnification. This type of construction is still used in very cheap models and in opera glasses or theater glasses. The Galilean design is also used in low magnification binocular surgical and jewelers' loupes because they can be very short and produce an upright image without extra or unusual erecting optics, reducing expense and overall weight.

I often get sent questions about peoples optics and one of the most common is "where can I get my binoculars repaired. As far as I have been able to find out pretty much any pair of binoculars can be repaired. You get some companies that specialise in niches like wartime and vintage binocular repairs and then obviously if you have a newer pair that is still under warranty you can get it repaired or even replaced by the manufacturer or distributor themselves. Again pretty much every problem can be repaired from collimation problems to even modifying some binoculars to focus closer. Once opened to be repaired, your waterproof binoculars can then even be re-sealed and purged again with zero grade nitrogen to ensure that they remain water and fogproof by some of the better repair companies. Binoculars can also be serviced, where they will be completely stripped down to be thoroughly cleaned both inside and out, new lubricants put on all moving parts and then sealed up once again.

Here is the path I took. Disassembly is not difficult if you work patiently, cautiously and gently. It is wise to make a written and or a photographic record that notes the correct placement and orientation of the components. Firmly grip and twist off the protective external guard rings. On occasion the gentle use of a strap wrench will aid.
