Did We Really Need Another Collimator? Yes- it’s an Ultra-Rare Genuine Navy Mark V!

In 2013, Oberwerk’s Kevin Busarow was trained in “Tail of the Arc” binocular collimation (alignment) on a Navy Mark V collimator by retired Navy Opticalman Cory Suddarth, of Suddarth Optical Repair. Shortly after returning from training in Oklahoma, Kevin built a working collimator from a surplus spy plane camera lens. The other necessary component- an auxiliary telescope- was supplied by Cory, with an extra-tall rhomboid prism for getting a direct view of the collimator image over the top of the larger binoculars that Oberwerk typically sells.
In August of 2018, when an ultra-rare genuine Navy Mark V collimator was put on the market by an optics collector in San Diego, Cory notified Kevin- and he jumped on it! With it’s massive 5-foot-long iron rail and solid copper housing, it was a beauty! Rather than risk trying to ship such a large, heavy, delicate, and irreplaceable piece of equipment, Kevin bought a one-way ticket to San Diego, rented a station wagon, and drove it back to Dayton, Ohio. Oberwerk has always been proud to say we’re the only binocular retailer on the planet (that we know of) with an in-house collimator- and now we have two at our disposal!

  1. More proof of your love of binoculars and caring customer support. Suddarth collimated a few of my binoculars – perfectly – over the years and anyone trained by him is truly an expert in this specialized field.
    My BT-82XL-ED is truly an amazing bino, BTW. Always comforting to know that when I order an Oberwerk product, it arrives in excellent condition.

  2. I am so glad these devices are still in operation. I had the pleasure of working with and overhauling no fewer than 12 MK V collimators. 2 while on USS Jason AR-8 as a 2nd Class petty officer. 2 while shop sup as a 1st class petty officer on USS Prairie AD-15. 4 at OM A School as the lead Navigation Instructor while still at Great Lakes, IL 2 on USS Orion AS-18 as a Chief Opticalman and shop supervisor. Then 2 more on USS Vulcan AR-5 as a Chief/Senior Chief Petty Officer and Shop supervisor. My overhauls included a total tear down. New paint of the frame and mounting mechanism, clean optics, reticle, new brass metal for the tube and overhaul or manufacture of the light fixture. I truly enjoyed this work and miss it greatly.
