General Binocular and Telescope repairs, etc.

All makes of binoculars and telescopes can be repaired in our workshop including Zeiss, Leitz, Leica, Nikon, Opticron, Avimo, Optolyth, Swarovski, Fujinon, etc. etc.

Straightforward correction of assembly, collimation and test can be carried out or a full strip- down for cleaning of mechanical components, renewal of lubricants with correct types, repairs, destaining and cleaning of optics, reassembly, adjustment for smooth operation, collimation, testing and external cleaning.
Roof prism types cost more to work on than porro prism types.

Nitrogen purging of water-proof or sealed instruments is carried out as part of the overhaul. Eyecups and other parts can be replaced or made if necessary. Also, optics can be recemented and often replaced when necessary./p>

Many of the instruments we receive, especially the older ones, have been tampered with by inexperienced people but usually they can be restored to serviceability by Optrep.

The photos that follow give an overview of Optrep's extensive work.

One of the oldest binoculars serviced by Optrep was this Carl Zeiss 8x ‘Feld stecher’ . First produced in 1894, this remarkable, benchmark binocular, still a pleasure to use today, was a sensation in its time. Of course, we also service the most modern binoculars. Examples of the more modern equipment that we repair and service: Leica 8x32 BN ‘Trinovid’ binoculars and a Leica APO-Televid 62 prismatic spotting scope.   Binoculars can be modified to focus closer, this being of special interest to birdwatchers. Older, but excellent, Leitz Trinovid and Zeiss Dialyt binoculars (10x40 examples illustrated) are particular candidates for this modification. A pair of Zeiss 10x40 BGA/T* 'Dialyt' binoculars stripped down for servicing in the Optrep workshop. The object lenses and the eyepieces lenses still have to be dismantled.   A typical 2-draw wood/brass telescope, this one by A. J. Natali of London and having a 40mm objective lens. This design continued with little change from about 1800, one being used by the Duke of Wellington at the Battle of Waterloo. The one illustrated was repaired by Optrep but it is often difficult or impossible to find lenses for these old telescopes because modern lenses are of a different specification. However, success is often achieved by Optrep.   Below are some modern prismatic telescopes recently repaired by Optrep, namely: Kowa TSN-773 ‘Prominar’ Opticron GS665GA Hawke ‘Endurance’ ED 65 Each one had suffered a fall and their damage included broken 2-speed focusing mechanisms. Once repaired, each was purged with nitrogen. All other makes are handled by Optrep including Leica, Nikon, Zeiss, etc.   The Carl Zeiss 'Diascope 65T*FL' prismatic spotting scope with zoom eyepiece above had a big fall and was badly damaged. Happily, Optrep were able to put it together again, making it as good as new.   Helios 100 B (90 degrees) binoculars.  Astronomical eyepieces can be fitted, including 22x, 33x and 40x.  Made in China.   A Russian “Cyclops 90” bi-ocular 90mm telescope. The angled prism housing appears to be based on that utilised on Russian microscopes and the eyepieces can take 1.25” astronomical eyepieces. The side focusing knob operates a rack and pinion inside to move one of the prisms. This telescope had a very bad fall but was restored by Optrep.
