One of the aspects that is appealing about these binoculars is the seemingly endless variety of fanciful brand names. It is a fun exercise (and insight into marketing strategy) to group some according to their themes. |

Why A Coat On My Binoculars ? Überzug (coat) auf Meinen Fernglas? Pourquoi mes Jumelles ont-elles Besoin d’un Couche (coat)? Почему бинокль помечены как " coated " ? ¿Por qué un Recubrimiento por Mis Prismáticos. Perché un Cappotto sul mio Binocolo? |
One encounters some binoculars marked “ coated ”; “ coated lens ”; “ coated optics ”; or “ fully coated ”. Or Verg ϋ tete (German for “coated”), Mehrfach Verg ϋ tete (German for “multi coated”), Voll Verg ϋ tete (German for “Fully Coated”), or Verg ϋ tete Optik (German for “coated optics”) . Or Optique Traitée (French for “coated optics” or Traitement Multicouche (French for”multicoated”). Or I.F.C . (“Independent Focus Coated”)or M.L.C (“Multi Layer Coated” . Inside a binocular when light encounters any air to glass interface, around 5% of the light is reflected. Binoculars may have up to 16 such interfaces, so this can result in up to half of the light (image) not being transmitted to your eye (hazy washed out image). Big objective lenses do compensate for light loss. Hence the use of huge military binoculars like my Flakfernrohr anti aircraft binoculars, and the giant “big eye” binoculars often used on ships. The principles of anti-reflective coatings were discovered by John William Strutt, 3rd Baron Rayleigh, in 1886. Naval warfare confers great advantage to whichever party that has the first sighting and identification. So commencing during wartime in the 1940’s, magnesium fluoride (MGF2)and other anti reflective lens coatings like Lithium Flouride were used to reduce light loss. Magnesium Fluoride is relatively hard wearing, has a decent refractive index, and is fairly easily applied by physical vapor deposition, so it is often used. Coated lenses were a deluxe feature during the time that both coated and uncoated lenses were first being sold. And so it was more likely that binoculars were marked as such and that binoculars advertisement touted that “deluxe” advancement. MGF2 applied to crown glass gives a reflectance of about 1%, compared to bare crown glass at 4% and that is just one surface. The thickness of the coating is directly related to the light wavelength it will pass. Coatings are usually configured in a compromise to pass light near the center of the visible spectrum (550 nanometers) which means more reflection at say 475 or 650. The very best binoculars these days use multiple different coatings, often 2 to 3 and potentially as many as 7, and may pass up to around 95% of the light. “Fully coated” means every optical surface is claimed to be coated, “coated optics” or “coated lens” means some are. The terms “AR”, “Anti Reflection”, “Anti Reflex” and “Antireflective” are sometimes terms encountered and they mean the same thing as “coated” but may have more modern consumer connotations. |
Big lenses, like those on my WWII military Flakfernrohr anti aircraft spotting binoculars on the left or my WWII Japanese naval military optics on the right pass more light, even though they may not be anti-reflective coated. That is why binoculars on WWII and earlier combat ships and those used for aircraft spotting tended to be large prior to the advent of coated lenses, to give the brightest most defined image, and to allow the earliest spotting and identification of potential enemies. So the tiny lenses in miniature binoculars can benefit from being coated. |

Corporate promotional items (called advertising specialties) have long been a popular form of marketing (think key chains and pens). You can walk away from a trade show with a whole bag overflowing with the stuff. In the past they included pen knives, box cutters, cigarette lighters, ashtrays, coasters, pocket calculators, pen pockets, pencils, toys, clocks, & beer can and bottle keys. (These days corporate lawyers do get nervous about anything related to smoking or drinking or that you can cut yourself with). There was normally a hierarchy of goodies: better stuff for good customers (distributors and dealers) who actually bought lots of your product and made you money, and the junky cheap stuff for consumers (think key chains and pens). Miniature binoculars were in the highest tier of better give away goodies. They may also have figured as corporate Xmas gifts, as prizes in sales competitions, or as corporate souvenirs for important visitors. So in addition to any brand name and manufacturer name, promotional binoculars will also have the name of the entity handing the binoculars out, which makes them fun to acquire. Today most advertising specialty companies offer a choice of hundreds of binoculars available for corporate purchase and custom markings. |
